Safety Instructions, Warnings, and Notes

2. Safety Instructions, Warnings, and Notes

Index of this chapter:

2.1 Safety Instructions

2.2 Warnings

2.3 Notes

2.1 Safety Instructions

Safety regulations require the following during a repair:

• Connect the set to the Mains/AC Power via an isolation transformer (> 800 VA).

• Replace safety components, indicated by the symbol h, only by components identical to the original ones. Any other component substitution (other than original type) may increase risk of fire or electrical shock hazard.

Safety regulations require that after a repair, the set must be returned in its original condition. Pay in particular attention to the following points:

• Route the wire trees correctly and fix them with the mounted cable clamps.

• Check the insulation of the Mains/AC Power lead for external damage.

• Check the strain relief of the Mains/AC Power cord for proper function.

• Check the electrical DC resistance between the Mains/AC Power plug and the secondary side (only for sets that have a Mains/AC Power isolated power supply):

1. Unplug the Mains/AC Power cord and connect a wire

between the two pins of the Mains/AC Power plug.

2. Set the Mains/AC Power switch to the "on" position

(keep the Mains/AC Power cord unplugged!).

3. Measure the resistance value between the pins of the

Mains/AC Power plug and the metal shielding of the tuner or the aerial connection on the set. The reading should be between 4.5 Mohm and 12 Mohm.

4. Switch "off" the set, and remove the wire between the

two pins of the Mains/AC Power plug.

• Check the cabinet for defects, to prevent touching of any inner parts by the customer.

Service Default Mode (see chapter 5) with a colour bar signal and stereo sound (L: 3 kHz, R: 1 kHz unless stated otherwise) and picture carrier at 475.25 MHz for PAL, or

61.25 MHz for NTSC (channel 3).

• Where necessary, measure the waveforms and voltages

with (D) and without (E) aerial signal. Measure the voltages in the power supply section both in normal operation (G) and in stand-by (F). These values are indicated by means of the appropriate symbols.

• Manufactured under license from Dolby Laboratories. “Dolby”, “Pro Logic” and the “double-D symbol”, are trademarks of Dolby Laboratories.

2.3.2 Schematic Notes

• All resistor values are in ohms, and the value multiplier is often used to indicate the decimal point location (e.g. 2K2 indicates 2.2 kohm).

• Resistor values with no multiplier may be indicated with either an "E" or an "R" (e.g. 220E or 220R indicates 220 ohm).

• All capacitor values are given in micro-farads (μ= x10 nano-farads (n= x10

• Capacitor values may also use the value multiplier as the decimal point indication (e.g. 2p2 indicates 2.2 pF).

• An "asterisk" (*) indicates component usage varies. Refer to the diversity tables for the correct values.

• The correct component values are listed in the Spare Parts List. Therefore, always check this list when there is any doubt.

2.3.3 BGA (Ball Grid Array) ICs

Introduction

For more information on how to handle BGA devices, visit this URL: www.atyourservice.ce.philips.com (needs subscription, not available for all regions). After login, select “Magazine”, then go to “Repair downloads”. Here you will find Information on how to deal with BGA-ICs.

), or pico-farads (p= x10

-12

2.2 Warnings

• All ICs and many other semiconductors are susceptible to

electrostatic discharges (ESD w). Careless handling during repair can reduce life drastically. Make sure that, during repair, you are connected with the same potential as the mass of the set by a wristband with resistance. Keep components and tools also at this same potential. Available ESD protection equipment: – Complete kit ESD3 (small tablemat, wristband,

connection box, extension cable and earth cable) 4822 310 10671.

– Wristband tester 4822 344 13999.

• Be careful during measurements in the high voltage section.

• Never replace modules or other components while the unit is switched "on".

• When you align the set, use plastic rather than metal tools. This will prevent any short circuits and the danger of a circuit becoming unstable.

2.3 Notes

2.3.1 General

• Measure the voltages and waveforms with regard to the chassis (= tuner) ground (H), or hot ground (I), depending on the tested area of circuitry. The voltages and waveforms shown in the diagrams are indicative. Measure them in the

BGA Temperature Profiles

For BGA-ICs, you must use the correct temperature-profile, which is coupled to the 12NC. For an overview of these profiles, visit the website www.atyourservice.ce.philips.com (needs subscription, but is not available for all regions) You will find this and more technical information within the "Magazine", chapter "Repair downloads". For additional questions please contact your local repair help desk.

2.3.4 Lead-free Soldering

Due to lead-free technology some rules have to be respected by the workshop during a repair:

• Use only lead-free soldering tin Philips SAC305 with order code 0622 149 00106. If lead-free solder paste is required, please contact the manufacturer of your soldering equipment. In general, use of solder paste within workshops should be avoided because paste is not easy to store and to handle.

• Use only adequate solder tools applicable for lead-free soldering tin. The solder tool must be able: – To reach a solder-tip temperature of at least 400°C. – To stabilize the adjusted temperature at the solder-tip. – To exchange solder-tips for different applications.

• Adjust your solder tool so that a temperature of around 360°C - 380°C is reached and stabilized at the solder joint. Heating time of the solder-joint should not exceed ~ 4 sec. Avoid temperatures above 400°C, otherwise wear-out of tips will increase drastically and flux-fluid will be destroyed.

Directions for Use

EN 7BJ3.1E LA 3.

To avoid wear-out of tips, switch “off” unused equipment or reduce heat.

• Mix of lead-free soldering tin/parts with leaded soldering tin/parts is possible but PHILIPS recommends strongly to avoid mixed regimes. If this cannot be avoided, carefully clear the solder-joint from old tin and re-solder with new tin.

2.3.5 Alternative BOM identification

The third digit in the serial number (example: AG2B0335000001) indicates the number of the alternative B.O.M. (Bill Of Materials) that has been used for producing the specific TV set. In general, it is possible that the same TV model on the market is produced with e.g. two different types of displays, coming from two different suppliers. This will then result in sets which have the same CTN (Commercial Type Number; e.g. 28PW9515/12) but which have a different B.O.M. number. By looking at the third digit of the serial number, one can identify which B.O.M. is used for the TV set he is working with. If the third digit of the serial number contains the number “1” (example: AG1B033500001), then the TV set has been manufactured according to B.O.M. number 1. If the third digit is a “2” (example: AG2B0335000001), then the set has been produced according to B.O.M. no. 2. This is important for

ordering the correct spare parts!

For the third digit, the numbers 1...9 and the characters A...Z can be used, so in total: 9 plus 26= 35 different B.O.M.s can be indicated by the third digit of the serial number.

Identification: The bottom line of a type plate gives a 14-digit serial number. Digits 1 and 2 refer to the production centre (e.g. AG is Bruges), digit 3 refers to the B.O.M. code, digit 4 refers to the Service version change code, digits 5 and 6 refer to the production year, and digits 7 and 8 refer to production week (in

example below it is 2006 week 17). The 6 last digits contain the serial number.

2.3.6 Board Level Repair (BLR) or Component Level Repair (CLR)

If a board is defective, consult your repair procedure to decide if the board has to be exchanged or if it should be repaired on component level. If your repair procedure says the board should be exchanged completely, do not solder on the defective board. Otherwise, it cannot be returned to the O.E.M. supplier for back charging!

2.3.7 Practical Service Precautions

• It makes sense to avoid exposure to electrical shock.

• Always respect voltages. While some may not be

AG 1A0617 000001

Figure 2-1 Serial number (example)

While some sources are expected to have a possible dangerous impact, others of quite high potential are of limited current and are sometimes held in less regard.

dangerous in themselves, they can cause unexpected reactions that are best avoided. Before reaching into a powered TV set, it is best to test the high voltage insulation. It is easy to do, and is a good service precaution.

5.1 Test Points

The chassis is equipped with test points (Fxxx) printed on the circuit board assemblies. As most signals are digital, it will be difficult to measure waveforms with a standard oscilloscope. Several key ICs are capable of generating test patterns, which can be controlled via ComPair. In this way it is possible to determine which part is defective.

Perform measurements under the following conditions:

• Service Default Mode.

• Video: Colour bar signal.

• Audio: 3 kHz left, 1 kHz right.

5.2 Service Modes

Service Default mode (SDM) and Service Alignment Mode (SAM) offers several features for the service technician, while the Customer Service Mode (CSM) is used for communication between the call centre and the customer. Also a service mode for servicing the AmbiLight units is foreseen.

This chassis also offers the option of using ComPair, a hardware interface between a computer and the TV chassis. It offers the abilities of structured troubleshooting, error code reading, and software version read-out for all chassis. Minimum requirements for ComPair: a Pentium processor, a Windows OS, and a CD-ROM drive (see also paragraph "ComPair").

5.2.1 Service Default Mode (SDM)

Purpose

• To create a pre-defined setting, to get the same measurement results as given in this manual.

• To override SW protections detected by stand-by processor and make the TV start up to the step just before protection (a sort of automatic stepwise start up). See paragraph “Stepwise Start Up”.

• To override SW protections detected by Viper (PNX8550). Depending on the SW version it is possible that this mechanism does not work correctly. See also paragraph “Error codes”.

• To start the blinking LED procedure (not valid in protection mode).

Specifications

Europe, AP(PAL/Multi) (analogue sets)

Europe, AP DVBT (digital sets)

• All picture settings at 50% (brightness, colour, contrast).

• All sound settings at 50%, except volume at 25%.

• All service-unfriendly modes (if present) are disabled, like: – (Sleep) timer. – Child/parental lock. – Picture mute (blue mute or black mute). – Automatic volume levelling (AVL). – Auto switch "off" (when no video signal was received

for 10 minutes). – Skip/blank of non-favourite pre-sets. – Smart modes. – Auto store of personal presets. – Auto user menu time-out.

How to Activate SDM

For DVBT TV’s there are two kinds of SDM: an analogue SDM and a digital SDM. Tuning will happen according table “SDM Default Settings”.

• Analogue SDM: use the standard RC-transmitter and key in the code “062596”, directly followed by the “MENU” button. Note: It is possible that, together with the SDM, the main menu will appear. To switch it "off", push the “MENU” button again.

• Digital SDM: use the standard RC-transmitter and key in the code “062593”, directly followed by the “MENU” button. Depending on the software version it is possible that the tuning will not work correctly. Note: It is possible that, together with the SDM, the main menu will appear. To switch it "off", push the “MENU” button again.

• Analogue SDM can also be activated by shorting for a moment the two solder pads [1] on the SSB, with the indication “SDM”. They are located outside the shielding. Activation can be performed in all modes, except when the set has a problem with the Stand-by Processor. See figure “Service mode pads”.

After activating this mode, “SDM” will appear in the upper right corner of the screen (if you have picture).

How to Navigate

When you press the “MENU” button on the RC transmitter, the set will toggle between the SDM and the normal user menu (with the SDM mode still active in the background).

How to Exit SDM

Use one of the following methods:

• Switch the set to STAND-BY via the RC-transmitter.

• Via a standard customer RC-transmitter: key in “00”sequence.

5.2.2 Service Alignment Mode (SAM)

Purpose

• To perform (software) alignments.

• To change option settings.

• To easily identify the used software version.

• To view operation hours.

• To display (or clear) the error code buffer.

How to Activate SAM

Via a standard RC transmitter: key in the code “062596” directly followed by the “INFO” button. After activating SAM with this method a service warning will appear on the screen, you can continue by pressing the red button on the RC.

Contents of SAM:

• Hardware Info. – A. SW Version. Displays the software version of the

VIPER software (main software) (example: BX31E-

1.2.3.4_12345 = AAAAB_X.Y.W.Z_NNNNN).

• AAAA= the software name.

• B= the region: A= AP, E= EU, L= LatAm, U = US. For AP sets it is possible that the Europe software version is used.

• X.Y.W.Z= the software version, where X is the main version number (different numbers are not compatible with one another) and Y.W.Z is the sub version number (a higher number is always compatible with a lower number).

• NNNNN= last five digits of 12nc code of the software.

– B. SBY PROC Version. Displays the software version

of the stand-by processor.

– C. Production Code. Displays the production code of

the TV, this is the serial number as printed on the back of the TV set. Note that if an NVM is replaced or is initialized after corruption, this production code has to

be re-written to NVM. ComPair will foresee in a possibility to do this.

• Operation Hours. Displays the accumulated total of operation hours (not the stand-by hours). Every time the TV is switched "on/off", 0.5 hours is added to this number.

• Errors. (Followed by maximal 10 errors). The most recent error is displayed at the upper left (for an error explanation see paragraph “Error Codes”).

• Defective Module. Here the module that generates the error is displayed. If there are multiple errors in the buffer, which are not all generated by a single module, there is probably another defect. It will then display the message “UNKNOWN” here. Not all errors will display a defective module name.

• Reset Error Buffer. When you press “cursor right” and then the “OK” button, the error buffer is reset.

• Alignments. This will activate the “ALIGNMENTS” submenu.

• Dealer Options. Extra features for the dealers.

• Options. regarding option codes, see chapter 8. Note that if you change the option code numbers, you have to confirm your changes with the “OK” button before you store the options. Otherwise you will lose your changes.

• Initialise NVM. When an NVM was corrupted (or replaced) in the former EMG based chassis, the microprocessor replaces the content with default data (to assure that the set can operate). However, all preferences and alignment values are gone now, and option numbers are not correct. Therefore, this was a very drastic way. In this chassis, the procedure is implemented in another way: The moment the processor recognizes a corrupted NVM, the “initialize NVM” line will be highlighted. Now, you can do two things (dependent of the service instructions at that moment): – Save the content of the NVM via ComPair for

– Initialize the NVM (same as in the past, however now it

Note: When you have a corrupted NVM, or you have replaced the NVM, there is a high possibility that you will not have picture any more because your display option is not correct. So, before you can initialize your NVM via the SAM, you need to have picture and therefore you need the correct display option. To adapt this option, you can use ComPair (the correct HEX values for the options can be found in the table below) or a method via a standard RC (described below). Changing the display option via a standard RC: Key in the code “062598” directly followed by the “MENU” button and “XXX”, where XXX is the 3 digit decimal display option code as mentioned in the first column of the next table. The decimal display option code can also be found on a sticker on the rear cover of the set. See figure “Display option code” for details. Make sure to key in all three digits, also the leading zero’s. If the above action is successful, the front LED will go out as an indication that the RC sequence was correct. After the display option is changed in the NVM, the TV will go to the Stand-by mode. If the NVM was corrupted or empty before this action, it will be initialised first (loaded with default values). This initialising can take up to 20 seconds.

• Store. All options and alignments are stored when pressing “cursor right” and then the “OK”-button

• SW Maintenance. – SW Events. Not useful for Service purposes. In case

of specific software problems, the development department can ask for this info.

– HW Events. Not useful for Service purposes. In case

of specific software problems, the development department can ask for this info.

• Operation hours PDP. Here you are able to reset the operations hours of the plasma display. This has to be done in case of replacement of the display. This option is not applicable for LCD sets.

• Upload to USB. Here you are able to upload several settings from the TV to a USB stick which is connected to the Side IO. The four items are “Channel list”, “Personal settings”, “Option codes” and “Display-related alignments”. First you have to create a directory “repair\” in the root of the USB stick.To upload the settings you have to select each item separately, press “cursor right”, confirm with “OK” and wait until “Done” appears. Now the settings are stored onto your USB stick and can be used to download onto another TV or other SSB. Uploading is of course only possible if the software is running and if you have picture. This method is created to be able to save the customer’s TV settings and to store them into another SSB.

• Download from USB. Here you are able to download several settings from the USB stick to the TV. Same way of working as with uploading. To make sure that the download of the channel list from USB to the TV is executed properly,

it is necessary to restart the TV and tune to a valid preset if necessary.

How to Navigate

• In SAM, you can select the menu items with the “CURSOR UP/DOWN” key on the RC-transmitter. The selected item will be highlighted. When not all menu items fit on the screen, move the “CURSOR UP/DOWN” key to display the next/previous menu items.

• With the “CURSOR LEFT/RIGHT” keys, it is possible to: – (De) activate the selected menu item. – (De) activate the selected sub menu.

• With the “OK” key, it is possible to activate the selected action.

How to Exit SAM

Use one of the following methods:

• Press the “MENU” button on the RC-transmitter.

• Switch the set to STAND-BY via the RC-transmitter.

Service Modes, Error Codes, and Fault Finding

5.2.3 Customer Service Mode (CSM)

Purpose

When a customer is having problems with his TV-set, he can call his dealer or the Customer Helpdesk. The service technician can then ask the customer to activate the CSM, in order to identify the status of the set. Now, the service technician can judge the severity of the complaint. In many cases, he can advise the customer how to solve the problem, or he can decide if it is necessary to visit the customer. The CSM is a read only mode; therefore, modifications in this mode are not possible.

When in this chassis, CSM is activated, a colour bar test pattern will be visible for 5 seconds. This test pattern is generated by the Pacific3. So if you see this test pattern you can determine that the back end video chain (Pacific3, LVDS and display) is working. Also new in this chassis: when you activate CSM and there is a USB stick connected to the TV, the software will dump the complete CSM content to the USB stick. The file (Csm.txt) will be saved in the root of your USB stick. This info can be handy if you don’t have picture.

How to Activate CSM

Key in the code “123654” via the standard RC transmitter.

Note: Activation of the CSM is only possible if there is no (user) menu on the screen!

How to Navigate

By means of the “CURSOR-DOWN/UP” knob on the RCtransmitter, you can navigate through the menus.

Contents of CSM

• Set Type. This information is very helpful for a helpdesk/ workshop as reference for further diagnosis. In this way, it is not necessary for the customer to look at the rear of the TV-set. Note that if an NVM is replaced or is initialized after corruption, this set type has to be re-written to NVM. ComPair will foresee a possibility to do this.

• Production Code. Displays the production code (the serial number) of the TV. Note that if an NVM is replaced or is initialized after corruption, this production code has to be re-written to NVM. ComPair will foresee a possibility to do this.

• Code 1. Gives the latest five errors of the error buffer. As soon as the built-in diagnose software has detected an error the buffer is adapted. The last occurred error is displayed on the leftmost position. Each error code is displayed as a 2-digit number. When less than 10 errors occur, the rest of the buffer is empty (00). See also paragraph Error Codes for a description.

• Code 2. Gives the first five errors of the error buffer. See also paragraph Error Codes for a description.

• Options 1. Gives the option codes of option group 1 as set in SAM (Service Alignment Mode).

• Options 2. Gives the option codes of option group 2 as set in SAM (Service Alignment Mode).

• 12NC SSB. Gives an identification of the SSB as stored in NVM. Note that if an NVM is replaced or is initialized after corruption, this identification number has to be re-written to NVM. ComPair will foresee a possibility to do this. This identification number consists of 14 characters and is built up as follows:

- 8 last characters of the 12NC of the SSB itself.

- the serial number of the SSB, which consists of 6 digits. Both can be found on a sticker on the PWB of the SSB itself (not on the sticker on the outside of the shielding!). The format of the identification number is then as follows: <last 8 characters of 12NC of SSB><serial number of SSB> (total 14 characters).

• Digital Natural Motion. Gives the last status of the Digital Natural Motion setting, as set by the customer. Possible

values are “Off”, “Minimum” and “Maximum”. See DFU on how to change this item.

• Pixel Plus. Gives the last status of the Pixel Plus setting, as set by the customer. Possible values are “On” and “Off”. See DFU on how to change this item.

• DNR. Gives the last status of the DNR setting, as set by the customer. Possible values are “Off”, “Minimum”, “Medium” and “Maximum”. See DFU on how to change this item.

• Noise Figure. Gives the noise ratio for the selected transmitter. This value can vary from 0 (good signal) to 127 (average signal) and to 255 (bad signal). For some software versions, the noise figure will only be valid when “Active Control” is set to “medium” or “maximum” before activating CSM. Noise figure is not applicable for DVBT channels.

• Headphone Volume. Gives the last status of the headphone volume, as set by the customer. The value can vary from 0 (volume is minimum) to 100 (volume is maximum). See DFU on how to change this item.

• Dolby. Indicates whether the received transmitter transmits Dolby sound (“ON”) or not (“OFF”). Attention: The presence of Dolby can only be tested by the software on the Dolby Signalling bit. If a Dolby transmission is received without a Dolby Signalling bit, this indicator will show “OFF” even though a Dolby transmission is received.

• Surround Mode. Indicates the by the customer selected sound mode (or automatically chosen mode). Possible values are “STEREO” and “VIRTUAL DOLBY SURROUND”. It can also have been selected automatically by signalling bits (internal software). See DFU on how to change this item.

• Audio System. Gives information about the audible audio system. Possible values are “Stereo”, ”Mono”, “Mono selected”, “Dual I”, “Dual II”, “Nicam Stereo”, “Nicam mono”, Nicam dual I”, “Nicam dual II”, “Nicam available”, “analogue In: No Dig. Audio”, “Dolby Digital 1+1”, “Dolby Digital 1/0”, “Dolby Digital 2/0”, “Dolby Digital 2/1”, “Dolby Digital 2/2”, “Dolby Digital 3/0”, “Dolby Digital 3/1”, “Dolby Digital 3/2”, “Dolby Digital Dual I”, “Dolby Digital Dual II”, “MPEG 1+1”, “MPEG 1/0”, “MPEG 2/0” and “Not supported signal”. This is the same info as you will see when pressing the “INFO” button in normal user mode (item “Sound”). When the audio is muted, there will be no info displayed.

• AVL. Indicates the last status of AVL (Automatic Volume Level) as set by the customer: See DFU on how to change this item.

• Delta Volume. Indicates the last status of the delta volume for the selected preset as set by the customer: from “-12” to “+12”. See DFU on how to change this item.

• Preset Lock. Indicates if the selected preset has a child lock: “LOCKED” or “UNLOCKED”. See DFU on how to change this item.

• Child lock. Indicates if “Child lock” is set to “UNLOCK”, “LOCKED” or “CUSTOM LOCK. See DFU on how to change this item.

• Lock after. Indicates at what time the channel lock is set: “OFF” or e.g. “18:45” (lock time). See DFU on how to change this item.

• Parental rating lock. Gives the last status of the parental rating lock as set by the customer. See DFU on how to change this item.

• Parental rating status. Gives the value of the parental rating status as sent by the current preset.

Service Modes, Error Codes, and Fault Finding

5.3 Stepwise Start-up

The stepwise start-up method, as known from FTL/FTP sets (EMG based sets) is not valid any more. There are two possible situation: one for protections detected by standby software and one for protections detected by main software. When the TV is in a protection state due to an error detected by standby software (and thus blinking an error) and SDM is activated via shortcutting the pins on the SSB, the TV starts up until it reaches the situation just before protection. So, this is a kind of automatic stepwise start-up. In combination with the start-up diagrams below, you can see which supplies are present at a certain moment. Important to know here is, that if e.g. the 3V3 detection fails (and thus error 11 is blinking) and the TV is restarted via SDM, the Stand-by Processor will enable the 3V3, but will not go to protection now. The TV will stay in this situation until it is reset (Mains/AC Power supply interrupted).

Mains

Off

Mains

When the TV is in protection state due to an error detected by main software (Viper protection) and SDM is activated via shortcutting the pins on the SSB, the TV starts up and ignores the error. Due to architectural reasons it is possible that the TV will end up in an undefined state (e.g. when the fast I

C bus is

blocked). In this case diagnose has to be done via ComPair.

The abbreviations “SP” and “MP” in the figures stand for:

• SP: protection or error detected by the Stand-by Processor.

• MP: protection or error detected by the VIPER Main Processor.

autonomous action

The audio protection circuit shuts down the supply autonomously. This triggers a set restart and during that restart (so at this check here), it will be observed t hat the audio protection line is high and the audio protection mode is entered. This condition is not valid for an SDI PDP. In this PDP set, the audio protection latch is not present and hence the HIGH condition here will never be observed. As a result, when an audio protection occurs, the set will restart and will enter a supply protection mode because of a missing power supply.

Switching on the power supply in an LPL scanning backlight set, also switches on the backlight supply. The display should not be used the first 5 seconds the backlight supply is running due to a pre-heat time of 4s and a 100% light output (not adjustable) the next second. This 5 second delay does not delay the startup of the display as this time is absorbed in the startup time of the rest of the system.

Audio Er ror

Switching the POD-MODE low in an FHP PDP set makes the CPUGO go high and starts the PDP CPU.

The availability of the supplies is checked through detect signals (delivered by

dedicated detect-IC's) going to the st-by µP. These signals are available for

+12V, +8V6, +5V, +1V2 and +2V5. A low to high transition of the signals should

occur within a certain time after toggling the standby line. If an observers is

detected before the time-out elapses, of course, the process should continue in

order to minimize start up time.

Switching the POD-MODE and the ON-mode low in an SDI PDP set makes the PDP supplies go to the ON mode.

- Only when the PDPGO is low, a retry should be considered (the PDP could have reset internally). If the PDPGO is already high, there is no use in trying to restart.

- PDPGO line is pulled high in all non FHP sets so this extra startup delay in case of a fault condition is not valid.

- Switching the PDPGO high will give a visual artefact and should only be done if really necessary.
