Safety and Maintenance Instructions, Warnings, and Notes

2. Safety and Maintenance Instructions, Warnings, and Notes

2.1 Safety Instructions

Safety regulations require that during a repair:

• Due to the chassis concept, a very large part of the circuitry (incl. deflection) is 'hot'. Therefore, connect the set to the mains via an isolation transformer.

• 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.

• Wear safety goggles when you replace the CRT.

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

• General repair instruction: as a strict precaution, we advise you to re-solder the solder connections through which the horizontal deflection current is flowing. In particular this is valid for the:

1. Pins of the line output transformer (LOT).

2. Fly-back capacitor(s).

3. S-correction capacitor(s).

4. Line output transistor.

5. Pins of the connector with wires to the deflection coil.

6. Other components through which the deflection current

flows.

Note: This re-soldering is advised to prevent bad connections due to metal fatigue in solder connections, and is therefore only necessary for television sets more than two years old.

• Check the insulation of the mains cord for external damage.

• Check the strain relief of the mains cord for proper function, to prevent the cord from touching the CRT, hot components, or heat sinks.

• Check the electrical DC resistance between the mains plug and the secondary side (only for sets that have an isolated power supply). Do this as follows:

1. Unplug the mains cord and connect a wire between the

two pins of the mains plug.

2. Turn on the main power switch (keep the mains cord

unplugged!).

3. Measure the resistance value between the pins of the

mains plug and the metal shielding of the tuner or the aerial connection of the set. The reading should be between 4.5 Mohm and 12 Mohm.

4. Switch the TV 'off' and remove the wire between the

two pins of the mains plug.

• Check the cabinet for defects, to prevent the possibility of the customer touching any internal parts.

2.3 Warnings

• In order to prevent damage to ICs and transistors, avoid all high voltage flashovers. In order to prevent damage to the picture tube, use the method shown in Fig. 2-1, to discharge the picture tube. Use a high voltage probe and a multi-meter (position V_dc). Discharge until the meter reading is 0 V (after approx. 30 s).

Figure 2-1 Discharge picture tube

• 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 potential. Available ESD protection equipment: – Complete kit ESD3 (small tablemat, wristband,

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

– Wristband tester 4822 344 13999.

• Together with the deflection unit and any multi-pole unit,

flat square picture tubes form an integrated unit. The deflection and the multi-pole units are set optimally at the factory. We do not recommend adjusting this unit during repair.

• Be careful during measurements in the high voltage section and on the picture tube.

• Never replace modules or other components while the unit is '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.

2.2 Maintenance Instructions

We recommend a maintenance inspection carried out by qualified service personnel. The interval depends on the usage conditions:

• When a customer uses the set under normal circumstances, for example in a living room, the recommended interval is three to five years.

• When a customer uses the set in an environment with higher dust, grease, or moisture levels, for example in a kitchen, the recommended interval is one year.

• The maintenance inspection includes the following actions:

1. Perform the 'general repair instruction' noted above.

2. Clean the power supply and deflection circuitry on the

chassis.

3. Clean the picture tube panel and the neck of the picture

tube.

• The picture tube panel has printed spark gaps. Each spark gap is connected between an electrode of the picture tube

2.4 Notes

2.4.1 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 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 (PAL) or 61.25 MHz (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 standby (F). These values are indicated by means of the appropriate symbols. and the Aquadag coating.

• The semiconductors indicated in the circuit diagram and in the parts lists, are interchangeable per position with the semiconductors in the unit, irrespective of the type indication on these semiconductors.

2.4.2 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 expressed in micro-farads (µ= x 10^-6), nano-farads (n= x 10^-9), or pico-farads (p= x 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 in the Electrical Replacement Parts List. Therefore, always check this list when there is any doubt.

To reflow the solder, apply a temperature profile according to the IC data sheet. So as not to damage neighbouring components, it may be necessary to reduce some temperatures and times

2.4.3 Rework on BGA (Ball Grid Array) ICs

General

Although (LF)BGA assembly yields are very high, there may still be a requirement for component rework. By rework, we mean the process of removing the component from the PWB and replacing it with a new component. If an (LF)BGA is removed from a PWB, the solder balls of the component are deformed drastically so the removed (LF)BGA has to be discarded.

Device removal

As is the case with any component that, it is essential when removing an (LF)BGA, the board, tracks, solder lands, or surrounding components are not damaged. To remove an (LF)BGA, the board must be uniformly heated to a temperature close to the reflow soldering temperature. A uniform temperature reduces the chance of warping the PWB. To do this, we recommend that the board is heated until it is certain that all the joints are molten. Then carefully pull the component off the board with a vacuum nozzle. For the appropriate temperature profiles, see the IC data sheet.

Area preparation

When the component has been removed, the vacant IC area must be cleaned before replacing the (LF)BGA. Removing an IC often leaves varying amounts of solder on the mounting lands. This excessive solder can be removed with either a solder sucker or solder wick. The remaining flux can be removed with a brush and cleaning agent. After the board is properly cleaned and inspected, apply flux on the solder lands and on the connection balls of the (LF)BGA. Note: Do not apply solder paste, as this has shown to result in problems during re-soldering.

Device replacement

The last step in the repair process is to solder the new component on the board. Ideally, the (LF)BGA should be aligned under a microscope or magnifying glass. If this is not possible, try to align the (LF)BGA with any board markers.

5.2.3 Customer Service Mode (CSM)

Purpose

When a customer is having problems with his TV-set, he can call his dealer. The service technician can than ask the customer to activate the CSM, in order to identify the status of the set. Now, the service technician can judge the severness 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.

How to enter

The CSM will be turned on after pressing the MUTE key on the remote control transmitter and any of the control buttons on the TV for at least 4 seconds simultaneously. This activation only works if there is no menu on the screen.

After switching ON the Customer Service Mode, the following screen will appear:

5.3 ComPair

5.3.1 Introduction

ComPair (Computer Aided Repair) is a service tool for Philips Consumer Electronics products. ComPair is a further development on the European DST (service remote control), which allows faster and more accurate diagnostics. ComPair has three big advantages: ComPair helps you to quickly get an understanding on how to repair the chassis in a short time by guiding you systematically through the repair procedures. ComPair allows very detailed diagnostics (on I2C level) and is therefore capable of accurately indicating problem areas. You do not have to know anything about I2C commands yourself because ComPair takes care of this. ComPair speeds up the repair time since it can automatically communicate with the chassis (when the microprocessor is working) and all repair information is directly available. When ComPair is installed together with the SearchMan electronic manual of the defective chassis, schematics and PWBs are only a mouse click away.

5.3.2 Specifications

ComPair consists of a Windows based faultfinding program and an interface box between PC and the (defective) product. The ComPair interface box is connected to the PC via a serial or RS232 cable. In this chassis, the ComPair interface box and the TV communicate via a bi-directional service cable via the service connector.

The ComPair faultfinding program is able to determine the problem of the defective television. ComPair can gather diagnostic information in two ways:

• Automatic (by communication with the television): ComPair can automatically read out the contents of the entire error buffer. Diagnosis is done on I2C level. ComPair can access the I2C bus of the television. ComPair can send and receive I2C commands to the micro controller of the television. In this way, it is possible for ComPair to communicate (read and write) to devices on the I2C busses of the TV-set.

• Manually (by asking questions to you): Automatic diagnosis is only possible if the micro controller of the television is working correctly and only to a certain extend. When this is not the case, ComPair will guide you through the faultfinding tree by asking you questions (e.g. Does the

screen give a picture? Click on the correct answer: YES / NO) and showing you examples (e.g. Measure test-point I7 and click on the correct waveform you see on the oscilloscope). You can answer by clicking on a link (e.g.

text or a waveform picture) that will bring you to the next step in the faultfinding process.

By a combination of automatic diagnostics and an interactive question / answer procedure, ComPair will enable you to find most problems in a fast and effective way.

Beside fault finding, ComPair provides some additional

features like:

EN 20 A10E BB5.

Service Modes, Error Codes, and Fault Finding

• Up- or downloading of pre-sets.

• Managing of pre-set lists.

• Emulation of the Dealer Service Tool (DST).

• If both ComPair and SearchMan (Electronic Service

Manual) are installed, all the schematics and the PWBs of the set are available by clicking on the appropriate hyperlink.

Example: Measure the DC-voltage on capacitor C2568 (Schematic/Panel) at the Mono-carrier.

– Click on the 'Panel' hyperlink to automatically show the

PWB with a highlighted capacitor C2568.

– Click on the 'Schematic' hyperlink to automatically

show the position of the highlighted capacitor.

5.3.3 How To Connect

1. First, install the ComPair Browser software (see the Quick Reference Card for installation instructions).

2. Connect the RS232 interface cable between a free serial (COM) port of your PC and the PC connector (marked with 'PC') of the ComPair interface.

3. Connect the mains adapter to the supply connector (marked with 'POWER 9V DC') of the ComPair interface.

4. Switch the ComPair interface “off”.

5. Switch the television set “off” with the mains switch.

6. Connect the ComPair interface cable between the

connector on the rear side of the ComPair interface (marked with 'I2C') and the ComPair connector at the rear side of the TV (situated just below the main aerial input).

7. Plug the mains adapter in a mains outlet, and switch the interface “on”. The green and red LEDs light up together. The red LED extinguishes after approx. 1 second while the green LED remains lit.

8. Start the ComPair program and read the 'Introduction' chapter.

5.4 Errors

5.4.1 Error code buffer

The error code buffer contains all detected errors since the last time the buffer was erased. The buffer is written from left to right. When an error occurs that is not yet in the error code buffer, it is written at the left side and all other errors shift one position to the right.

Use one of the following methods:

• On screen via the SAM (only if you have a picture). Examples:

– ERROR: 0 0 0 0 0 : No errors detected – ERROR: 6 0 0 0 0 : Error code 6 is the last and only

detected error

– ERROR: 9 6 0 0 0 : Error code 6 was first detected and

error code 9 is the last detected (newest) error

• Via the blinking LED procedure (when you have no picture). See next paragraph.

• Via ComPair.

5.4.3 How to Clear the Error Buffer

The error code buffer is cleared in the following cases:

• By activation of the CLEAR command in the SAM menu:

• When you exit SDM / SAM with the STANDBY command

on the remote control (when leaving SDM / SAM, by disconnecting the set from Mains power, the error buffer is not reset).

• When you transmit the command DIAGNOSE-99-OK with ComPair.

• If the content of the error buffer has not changed for 50 hours, it resets automatically.

5.4.4 Error Codes

In case of non-intermittent faults, clear the error buffer before you begin the repair. These to ensure that old error codes are no longer present. If possible, check the entire contents of the error buffer. In some situations, an error code is only the result of another error code and not the actual cause (e.g., a fault in the protection detection circuitry can also lead to a protection).

Error 0 = No error

Error 1 = X-ray protection, E/W protection and/or IBeam.

The set is switched to protection; error code 1 is placed in the error buffer; the LED will blink 1 time (repeatedly). If this happens, isolate each circuit to determine the cause. These circuits are:

• X-Ray protection (PROTN). If this protection is active, the most likely cause is the LOT. Detection via pin 3 of the BOCMA (item 7301).

• EW protection (PROT-UP). If this protection is active, the causes could be one of the following; – Bad contacts of: horizontal deflection coil, linearity coil

5417, S-correction capacitor 2418/2419, flyback capacitor 2414/2416, or line output stage.

– Short circuit of: flyback diode 6414, EW transformer

(bridge coil) 5478/5479 or 5474/5475/5476 (version dependent), or EW driver 7470.

• High beam current protection (IBEAM). As the name implies, the cause of this protection is a too high beam current (bright screen with flyback lines). Check whether the +200 V supplies to the CRT panel is present. If the voltage is present, the most like cause is the CRT panel or the picture tube. Disconnect the CRT panel to determine the cause. If the +200 V voltage is not present, check R3840 at CRT-panel and R3445 / D6445 at main panel.

Error 2 = Vertical protection (VFB). If this protection is active, the cause could be one of the following (most likely in the vertical output stage):

• 7501 is faulty.

• Poor contact or open circuit of deflection coil.

• +13 V-VERT and/or -13 V not present.

Error 3 = Reserved

Error 4 = +5 V protection. If the 5 V protection is active, the set

is switched to protection, error code 4 is placed in the error buffer, and the LED will blink 4 times (repeatedly). A 5 V failure can cause a drop in the 5 V supply output, resulting in an undefined behaviour of the set. Therefore, all I2C devices connected to the 5 V supply are constantly monitored. When none of these devices respond to the micro controller for a prolonged time, the micro controller assumes that there is a failure in the 5 V supply. By starting up the set with the service jumpers shorted, the 5 V protection is disabled and it is easier to determine the cause.

+5 V protection will be activated when these I2C devices fail (no I2C communication):

• Main Tuner 1125 on main panel.

• ITT sound processor MSP34xx (7064) on the SSB.

The following tips are useful to isolate the problem area after overriding the +5V protection. Determine whether:

• The +5 V source is working properly; isolate coil 5430 and jumper 9044 and measure the +5V

• ITT sound processor circuit is loading the +5 V; isolate coil

5430.

• The tuner is loading the +5 V source; isolate jumper 9044.

• Main tuner circuit is loading the +5 V source; isolate coil

5261.

Caution: Overriding the 5 V protection when there is a 5 V failure can increase the temperature in the set and may cause permanent damage to components. Do not override the 5 V protection for a prolonged time.

Error 5 = Reserved.

Error 6 = General I2C error. This will occur in the following

cases:

• SCL or SDA is shorted to ground.

• SCL is shorted to SDA.

• SDA or SCL connection at the micro controller is open

circuit.

Error 7 = BC-loop not stabilised (BCF = 1) Black current loop instability protection. The possible cause could be a defect in one or more of the RGB amplifiers, RGB guns or RGB driving signals.

Error 8 = BOCMA IC TDA888xx I2C communication failure. BOCMA (item 7301 on SSB) is corrupted, or the I2C line to the BOCMA is low, or no supply voltage present at pin 14 and/or pin 60 (3V3).

Error 9 = BOCMA IC TDA888xx 8 V failure (SUP bit). No supply voltage at pin 53. Check NFR 3331 and coil 5333.

Error 10 = NVM I2C error. NV memory (item 7066) does not respond to the micro controller.

Error 11 = Micro controller / NV Memory identification error. During the last start-up, the NVM and the micro controller did not recognize each other (e.g. one of them was replaced or the NVM memory has been changed/adapted or lost); therefore, the NVM was loaded with default values.

Error 12 = Microprocessor (item 7064) internal RAM test failure.

Error 13 = Main Tuner I2C failure UV13xx. Tuner (item 1225) is corrupted, or the I2C line to the Tuner is low, or nosupply voltage at pin 9, pin 6 or 7 of the tuner.

Error 14 = Sound processor I2C error (MSP34xx). Sound controller MSP3400 or MSP3410 does not respond to the micro controller.

Error 15 = SRAM IC uPD431000A-B test failure (item 7070).

Error 24 = IO expander IC (IC7008 - PCF8574 on Dig. Interf.

panel) I2C communication failure.

Error 25 = IBO+ microprocessor (IC7100 - PNX8525) I2C communication failure.

Note: Error codes 1, 2, and 4 are protection codes and in this case, supply of some circuits will be switched “off”. In addition, in protection, the LED will blink the number of times equivalent to the most recent error code.

EN 22 A10E BB5.

Service Modes, Error Codes, and Fault Finding

5.5 The Blinking LED Procedure

Via this procedure, you can make the contents of the error buffer visible via the front LED. This is especially useful when there is no picture.

When the SDM is entered, the LED will blink the contents of the error-buffer. Error-codes ≥ 10 are shown as follows:

• A long blink of 750 ms (which is an indication of the decimal digit),

• A pause of 1.5 s,

• n short blinks (n = 1 - 9),

• When all the error-codes are displayed, the sequence

finishes with a LED blink of 3 s,

• The sequence starts again.

Example of error buffer: 12 9 6 0 0 After entering SDM:

• 1 long blink of 750 ms followed by a pause of 1.5 s,

• 2 short blinks followed by a pause of 3 s,

• 9 short blinks followed by a pause of 3 s,

• 6 short blinks followed by a pause of 3 s,

• 1 long blink of 3 s to finish the sequence,

• The sequence starts again.

5.6 Protections

If a fault situation is detected an error code will be generated and if necessary, the set will be put in the protection mode. Blinking of the red LED at a frequency of 3 Hz indicates the protection mode. In some error cases, the microprocessor does not put the set in the protection mode. The error codes of the error buffer can be read via the service menu (SAM), the blinking LED procedure or via ComPair. The DST diagnose functionality will force the set into the Service-standby, which is similar to the usual standby mode, however the microprocessor has to remain in normal operation completely.

To get a quick diagnosis the chassis has three service modes implemented:

• The Customer Service Mode (CSM).

• The Service Default Mode (SDM). Start-up of the set in a

predefined way.

• The Service Alignment Mode (SAM). Adjustment of the set via a menu and with the help of test patterns.

See for a detailed description: Chapter 9 paragraphs “Deflection” and “Power Supply” of the A10E Service manual.

5.7 Troubleshooting Tips

In this paragraph, some troubleshooting tips for the deflection and power supply circuitry are described.

position numbers 9409 (in this case the EW protection is disabled). If the basic deflection is working (picture is parabolic distorted), then the fault is located in the EW circuit/panel. If there is no hor. deflection, the fault is present in the basic deflection circuitry.

• Also, take note of protection circuits in the line output stage. If any of these circuits are activated, the set will shut down. Depending on protections, the LED will blink according to the fault defined. In order to determine which protection circuit is active, isolation of circuits is necessary. These protection circuits are:

– High beam protection: See error “1”. – X-ray protection: See error “1”.

• If the high beam protection or the X-ray protection is active,

it will switch the set to protection and the SDM is activated. The service LED blinks repetitively 1 time. If this happen, isolate each circuit to determine the cause.

5.7.2 Power Supply

To trouble shoot the A10 SMPS, first check the +5 V_STBY voltage on IC7968, pin 3 / 4. If this voltage is not present, check fuse 1961 and D6961. If 1906 or D6917 is not open circuit, the problem might be caused on the primary side of the switching supply. Check the output of the bridge diodes at the cathode side of D6912/D6913 or D6915-pin 1 for approximately 300 V_dc. If this voltage is missing, check the bridge diodes and the fuse. If fuse F1900 is found open, check IC7921 (circuit A1) between pins 3 and 2 to make sure that there is no short circuit present. If the 300 V_dc is present on pin 3 of IC7902, check for a startup voltage of 16 V on pin 4 of IC7921. If this start-up voltage is not present, check if R3914 is open (a short circuit between pin 4 and 5 will also cause this problem). It is necessary to have a feedback signal from the hot secondary side of switch mode transformer T5912 at pin 8 and pin 9 for the power supply to oscillate. If this start-up voltage is present on pin 4 of IC7902 and the supply is not oscillating, check R3929 and D6929.

The A10 power supply has been designed with Over Voltage Protection (OVP). To determine whether OVP is active, check whether V_BAT (141 V) is present at IC7971 pin 1. If not, check the components D6938, C2939 and C2940 and L5941. If these components are o.k., then check voltage at pin 3 of IC 7942. If this voltage is not present check fuse 1941 and fuse 1942. Replace if necessary. If the dc-voltage is present at pin 3, replace opto-coupler 7929. Another way to confirm whether OVP is active is to measure the voltage with an oscilloscope at IC7902 pin 4. If the voltage is fluctuating between 11-14 V, then check the components as described in the above mentioned paragraph.

5.7.3 Other Problems (related to CSM)

Picture problems

5.7.1 Deflection Circuit

• Measure if the V_BAT (140 V) is present across 2939/2940 (A1 POWER SUPPLY). If the voltage is not present, disconnect jumper 9936 and 9937 (see A1 Power Supply). The whole Line Deflection stage is now disconnected. If the voltage is present, then the problem might be caused by the deflection circuit. Possibilities: – Transistor 7410 is defective.

Note: If the C and E of 7410 are shorted, hick-up noise can be heard from the power supply circuit

– The driver circuit around transistor 7481 is faulty – No horizontal drive signal coming from the BOCMA IC

7301 pin 56 on the SSB

• To determine whether the fault is present in the line deflection circuit (A2 LINE DEFLECTION) or in the EW circuit/panel (screen size above 21”), insert jumper into

TV switched off or changed channel without any user action

Set switches off after “TV SWITCHING OFF” was displayed: “Auto standby” switched the set off because:

5.8 Flash-card Handling For SW Downloading

5.8.1 General

You must NOT:

• Use Sony writers.

• Format the cards.

• Use a flash-card from Apacer.

• Use flash-cards > 256 MB

You must:

• Use USB writers. Use a PCMCIA card adapter and a laptop.

• Use brands Kingston and Sandisk for flash-cards.

• Use flash-card of sizes of 32 MB, 64 MB, 128 MB and 256

MB.

• Use a DOS box or Windows Explorer to copy the two images (FCL.IMG and IBOP.IMG) to the flash-card. Those two files form a pair. Always copy both images (from the same delivery!). Make very sure that the images, which you are trying to install, are made for that particular board model and that particular board version. In addition, the Software version or model should differ from the version or model, which is already on the board. If it does not differ, no download will take place (unless the software on the board was faulty).

• In order to make sure that the writing indeed has finished, you must do the following before removing the card: Software “Eject” or “Disconnect” the driver (should be a command of your flash-card writer, which you can see when you right-click on the flash-card drive from the explorer.) If you forget this, not all data is flashed to the card, resulting in incomplete files on the flash-card.

5.8.2 Solving problems

In case of any troubles, first do the following to check whether

the copy was good:

1. Remove the flash-card (so that the cache memory is cleared).

2. After 10 seconds, re-insert the flash-card.

3. Open a DOS box and type "fc /b <image on card> <image

on harddisk>". This command does compare the copy of the image with the original, which should not have any differences.

You put a flash-card in and the system does nothing. The flash-card loader is copying the image to flash. This can take up to 1.5 minutes (for large images).

Whenever you reset the board, an application is launched.

• Press the flash-card firmly into it's slot; if it is not inserted properly the available application will launch

• Check (with an PC / laptop) that the flash-card contains both a FCL.IMG and a IBOP.IMG.

• Always copy both images as the FCL.IMG and the IBOP.IMG form a pair.

The flash-card images do not download (board keeps on resetting or IBL is launched, or another application is launched from NAND-flash).

• Make sure the Software Version you try to download is different from the one in the box.

• Make sure the Hardware Version is set correctly. L0, L1, and L2 boards all use different flash-card images.

• Make sure the contents of the flash-card are readable (check with NT); try another flash-card and another flashcard writer on another PC to be 100% sure. Do not format the flash-card.

Flashing of NOR-image does not work. Remove the stream server (!).

Flashing of NAND-flash does not work. Check the size of the IBOP.IMG image. It should not exceed +/- 15 MB.

Tip: If it is possible, one can remove the shielding from the board. The IBO+ board usually contains two LEDs. During flashing, they are orange. If the flashing succeeded, then the LED will turn GREEN for 10 seconds. If the flashing did not work, then the LED will stay RED for 10 seconds. With these LEDS, you can see the difference between:

• Board does not even attempt to flash (images already in this board or are not acceptable for this board).

• Board fails the flash-card download (images corrupt; flashcard unreadable: FCL.IMG not consistent with IBOP.IMG).

• Board succeeds (no problem whatsoever)
