3.1 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 M and 12 M.

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.

• 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.

3.3.2 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 k).

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

• All capacitor values are given in micro-farads (10

-6

nano-farads (n 10

-9

), or pico-farads (p 10

-12

• 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 on the Philips Spare Parts Web Portal.

Precautions, Notes, and Abbreviation List

EN 6 Q552.2L LA3.

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. SN is Lysomice, RJ is Kobierzyce), 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 2010 week 10 / 2010 week 17). The 6 last digits contain the serial number.

5.1 Test Points

As most signals are digital, it will be difficult to measure waveforms with a standard oscilloscope. However, 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: Color 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.

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. (see also section “5.4.1 ComPair

”).

Note: For the new model range, a new remote control (RC) is

• 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). – Skip/blank of non-favorite pre-sets.

How to Activate SDM

For this chassis there are two kinds of SDM: an analogue SDM and a digital SDM. Tuning will happen according Table 5-1

• Analogue SDM: use the standard RC-transmitter and key in the code “062596”, directly followed by the “MENU” (or “HOME”) button. Note: It is possible that, together with the SDM, the main menu will appear. To switch it “off”, push the “MENU” (or "HOME") button again. Analogue SDM can also be activated by grounding for a moment the solder path on the SSB, with the indication “SDM” (see Service mode pad

• Digital SDM: use the standard RC-transmitter and key in the code “062593”, directly followed by the “MENU” (or "HOME") button. Note: It is possible that, together with the SDM, the main menu will appear. To switch it “off”, push the “MENU” (or "HOME") button again.

• In SAM, the menu items can be selected 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:

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

• Via a standard RC-transmitter, key in “00” sequence, or select the “BACK” key.

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 test pattern will be displayed during 5 seconds (1 second Blue, 1 second Green and 1 second Red, then again 1 second Blue and 1 second Green). This test pattern is generated by the PNX51X0 (located on the 200Hz board as part of the display). So if this test pattern is shown, it could be determined that the back end video chain (PNX51X0 and display) is working.For TV sets without the PNX51X0 inside, every menu from CSM will be used as check for the back end chain video.

When CSM is activated and there is a USB stick connected to the TV set, the software will dump the CSM content to the USB

How to Navigate

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

Contents of CSM

The contents are reduced to 3 pages: General, Software versions and Quality items. The group names itself are not shown anywhere in the CSM menu.

General

• 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 in a possibility to do this. The update can also be done via the NVM editor available in SAM.

• 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 in a possibility to do this. The update can also be done via the NVM editor available in SAM.

• Installed date. Indicates the date of the first installation of the TV. This date is acquired via time extraction.

• 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 in a possibility to do this. This identification number is the 12nc number of the SSB.

• 12NC display. Shows the 12NC of the display.

• 12NC supply. Shows the 12NC of the power supply.

• 12NC 200Hz board. Shows the 12NC of the 200Hz Panel (when present).

How to Exit CSM

5.3 Stepwise Start-up

When the TV is in a protection state due to an error detected by stand-by software (error blinking is displayed) and SDM is activated via shortcutting the SDM solder path 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. Caution: in case the start-up

in this mode with a faulty FET 7U0X is done, you can destroy all IC’s supplied by the +1V8 and +1v1, due to overvoltage (12V on XVX-line). It is recommended to measure first the FET 7U0X or others FET’s on shortcircuit before activating SDM via the service pads.

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 MIPS Main

Processor.

secondsago. (to prevent LCD display problems)

The assumption here is that a fast toggle (<2s) can

only happen during ON->SEMI ->ON. In these states,

the AVC is still active and can provide the 2s delay. A

transition ON->SEMI->STBY->SEMI->ON cannot be

made in less than 2s, because the standby state will

be maintained for at least 4s.

Constraints taken into account:

-Display may only be started when valid LVDS output clock can be delivered by the AVC.

-To have a reliable operation of the EEFL ba cklight, the backlight should be driven with a maximum PWM duty cycle during the first seconds. Only after this first one or two seconds, the PWM may be set to the required output level (Note that the PWM output should be present b

efore the backlight is switched on). To minimize the artefacts,

the picture should only be unblanked after these first seconds.

Wait until valid and stable audio and video, corresponding to the

requested output is delivered by the AVC

AND

the backlight has been switched on for at least the time which is

indicated in the display file as preheat time.

CPipe already generates a valid output clock in the semi-standby state: display
