Sony KDF-E55A20 55 in. LCD Television Logo

Posted on Mar 20, 2017

My sony KDF-E55A20 tv stopped working the other day. The stand-by light blinks green 6 times, then blinks red 6 times. After a while the 6 red blinks turn into 10 red blinks. I have figured out what the blinks mean but I need someone to translate them to me because I do not speak "tech". The 6 red blinks apparently mean: No horizontal (H stop), No Raster, Goes to the blinking self-diagnosis function immediately. Check C515 & C516 and the jungle IC, IC206 The 10 red blinks apparently mean: Check Q8014 & Q8013 for shorts, leakage, or bad solder connections on the "D" board. If the transistors are bad, check R8051 & IC8005, also on the "D" board. Any help would be greatly appreciated.

I'm not sure about the reliability of the information you got. According to the service manual, 6 blinks on this set (KP57WS500) indicates a low B+ condition, a short or load on the 5 volt line, probably on the A or B boards. Start by checking IC2 on the A board, this is the 5 volt regulator. If it is good, then you have to start disconnecting things to see what's loading the line. I would suggest the video driver IC's which are on the CRT pcbd's, you can disconnect them one at at time and monitor the 5 volt line to see if it comes up. Remember to rate this soltuion please. Thanks!

SOURCE: powers on only sometimes / red standby light blinks

If you actually have a flat panel set, then the "fix" you list is not applicable. Those are for a standard CRT based Sony set. Can you please post the make and model of your unit. We can then look up the diagnostic code and provide you with a proper diagnosis and solution.

Thanks,
Dan

SOURCE: TV will not turn on

Sounds like the thermal fuse has gone bad. Sony part# 191002393. Very enexpensive part. It is located near the lamp housing from the back of the set. Once you have the new part in your hand, it will be easy to find.

Sony KDF-E55A20 55 in. LCD... Problem red light flashes 5 times

A 5 blink error indicates a bad lamp driver. However a lamp may possibly cause this too. I suggest putting a new lamp in if you have one just to verify the lamp is not the problem. If it still fails with a new lamp then the lamp driver is the problem. This part should be replaced by a Sony authorized servicer. The lamp can be replaced easily by you. The lamp replacement instructions are in the TV's owners manual. Good Luck
