Sony KDF55XS955, 5X GREEN THEN 6X RED BLINKS, SCREEN BLACK

Hello,
power supply board is dead, u know basic electronics' and soldering? Most of the times, the power supply board just have dead leakages gases capacitors.These capacitors always bulges up on it top,or puff up on it top.Replaced these gases leakages capacitors will get your TV power stable,and work again.Or tries websites like Shopjimmy.com,Ebay.com to buy a whole refurbish power supply board for the replacement.


Take care.....

need to know how many time the red light is blinking there should be a pause. 4 blinks is a fan, 3 blinks is the lamp door is not closed 6 blinks is thermal sensor.

Its not the green light that you should be count but the red. How many times is it blinking? Here is a quick update of the errors that are most common.

3x - Lamp switch not engaged
4x - Fans issue
5x - Lamp
6x - Thermal fuse

5 times Red LED blinks means Lamp Driver Error. (KDF-55WF655)
2 possible reasons, either Lamp is gone or Ballast Supply got bad.
Replace lamp first, in most cases it solved the problem.
How old is this TV and did you replaced lamp recently?
Thanks.

Ths 5 blinks usually indicate an AKB problem. There is a break in the video path. I'll look up your specific model and post the results here. Please update this if you wish to attempt the repair yourself.

Thanks,

It is unusually to see BOTH of these flash codes together. I have never seen them at the same time. A 5 flash is a lamp driver error, which is possibly related to your lamp failure. You may have to replace the lamp driver or "ballast" to correct this problem. The 6 flash is a power supply problem and more serious, as it will likely take a technician to narrow down exactly where the fault lies. It may be a thermal fuse open OR a failure in the power supply itself. What was the original symptom that caused you to replace the lamp? Did you use an original Sony lamp as a replacement?

Green flashing is normal. Red flashes are error codes. Count the error flashes.

3x - Lamp cover position or cover detect switch bad.
4x - One or more fans failed RPM test
5x - Lamp power supply/ballast failure
6x - Thermal fuse failed (usually)

in this set 3 blinks means lamp cover not set properly but i think that your problem is your 6x red blinks that means you have a problem in the audio section in your set(missing a voltage) or a themal fuse open.

The problem you have is a failed thermal sensor. Depending on how tech savvy you are you can replace it.They have changed the way the thermal sensor looks but it isnt too bad too put in. Any repair shop should also be able to do this for you.

Part number is 1-910-006-44 Themal Fuse Sony Part.
