Sony KDS55A2000 Red Blinking Light Issue

After trying to power up for 15 seconds or so the red blinking Power LED, that I have read about several times on this site, kicks on. My red Power LED is blinking 9 times after trying to power up as opposed to 4, 5, or 6 times as I have read about on here. I have already put in a new lamp as that's what the certified technician told me to do when he came out. With the new lamp the set worked fine for about a week but now the problem has resurfaced.

After experiencing this problem this morning I completed a hard reset tand the set came back on for me. About an hour later the set shut off and the red LED blinked 9 times again an then the set successfully powered itself back up.

I am horribly frustrated with this nearly new $2,400 set. Unfortunately I made a bad decision and did not purchas the warranty from Best Buy. Any assistant will be very much appreciated.

    Might also be worth noting that after powering itself back up (after the shut down and subsequent 9 blinks) I can hear a fan working much much harder than normal.

    i'm having a sony certified tech come out on friday. after enough persistance on the phone with Sony this afternoon I convinced them to extend my manufacturers warranty so that this repair is covered. I'm in month 14 and the warranty was only for 12. I'll let ya know the official diagnosis.

Sounds like you have a system board issue. The fan only works when required, and something on the board, or perhaps the power supply board, is running too hot. That would explain the blinking red lamp, which indicates an 'unfavorable' operating condition. I'm assuming that with your extended warranty statement from BestBuy, you're saying that you are no longer covered by warranty? I thought that the warranty was at least a full year, no?

The resolution is to order one of two parts, the system board, or the power supply board. I just did one of those here on Hawaii, and the fellow was happy he had that service warranty. Maybe you can call them up, and extend it? Don't know their policies on that, actually. Sounds like you are not in 'hard failure' mode, yet, but you'll be there soon enough. When did the service tech come out last?

First off
For the KDS55A2000, 9 blinks, pause, 9 blinks means "Device error" and the probable cause locations listed are as follows:

1. Temperature sensors
2. Bus decoder ICs (IC2000, 3150, 3200, 8804)

These are starting points for qualified service technicians. There is a service bulletin for this issue, but it is intended for use by qualified service technicians.
I found that it refers to a problem in the "zero crossing detector" circuit on the "G" board. I resourced the part from an electronics warehouse and found out that the "G" board has a known weakness and high failure rate The part cost me $73+$47 fedex shipping
The "G" board may be the only "plug n' play" board in the whole set

No power to tv. When i press the power button i only get a blinking green light then it stops and the blinking red light for lamp flashes and keeps flashing


You need to replace your lamp. Also check power supply and ballast board. Most of the time if you replace the lamp it will come back up. After replacing the lamp you will need original remote to reset lamp hours.

I have a blinking red light with no picture


Blinking red light shows TV got some problem internally and need to be repaired.
Now important thing is how many times that red light blinking? There would be pause of 3 seconds in blinks so count pause to pause and let me know to find out possible cause of problem.
Is it Sony KDS-55A2000 model TV or any other model?

Kds55a2000 red light flashing


The SONY Owner's Manual for the KDS55A2000 does not state what the 4 times blinking Power LED means.

However, my Sony Extended Care Service support insists that the projection lamp is the cause for the 4X blinking LED
Power light.
I do not agree but am forced to buy a replacement lamp (not cheap) to prove that the problem is probably the fan, as the TV Technician states elsewhere in these FixYa support questions and answer

Slow blinking red light


Yes you can first try this:. Red status LED, self-diagnosis error 44, check for open F9A06 on the Power PCB part # 283P128050 on the Power PCB 2. Red lamp LED, self diagnosis error 34. Check for 5-volts DC at J-9 connector pin 1 and 2 on the Engine Driver PCB if missing replace the Power PCB part # 930B921002 3. LED stops blinking after 70 seconds of plug in but will not power on. This model is equipped with a keyboard lock feature, this can be mistaken as a no power condition. To unlock the keyboard press and hold the "menu" button on the front panel for 10 seconds 4. LED stops blinking after 70 seconds of plug in but will not power on. Check for 3.2 volts DC at connector LE pin 3 and 4 on the Control PCB, if low suspect problems with the switches/buttons on the Control PCB part # 935D776001 5. LED stops blinking after 70 seconds of plug in but will not power on. Keyboard is not locked and key inputs at connector LE pin 3 and 4 check good. Suspect the E2P PCB part # 934C121001 6. LED does not stop blinking after 70 seconds of plug in. Disconnect the USB connector from the card reader to the front from the Chassis, if the unit will then boot up replace the Card Reader part # 299P271010. 7. LED does not stop blinking after 70 seconds of plug in. Disconnecting the USB connector from the Card Reader did not help. Suspect the DM PCB part # 934C116002
