Question about Sony KDF-E55A20 55 in. LCD Television

1 Answer

Screen goes black, 5 blinking red lights, screen back on for 20 seconds....cycle continues

Set is two years old. After about a minute the screen will go black. If I leave it alone the picture will come back on after about a minute, but then it goes off again. When the picture goes off, if I hit power off then on again I get 5 blinking red lights on the power indicator and the fan becomes very loud. I don't know all that much about this tv but it doesn't seem like a lamp issue. When the screen is on the picture is fine but it seems like something is overheating.

HELP!! I bought a new thermal fuse hoping that is it. I have no idea how to replace it or where the thermal fuse is located in the set. Could it be the thermal fuse? something else?

Thank You in advance

    Thank you for your input. The only reason I wasn't thinking lamp was because the lamp symptoms people talk about on the board (screen becoming darker, popping sound etc) weren't happening to me. I'll take your advice and change it.



    Thanks again

    goes off but comes back on with picture first, but no sound, sound comes on 5-10 seconds later. Lamp shouldn't affect sound should it?

Let me first say that if you are getting 5 blinks its not the thermal fuse. Your problem is your Lamp. You have what we call an intermittent Lamp. The only way to fix this is to replace the lamp. Part Number A-1085-337-A. Average cost $217.00

Image goes black and then returns shortly after


Many sets that use lamps do this right before the lamp fails--average life is 2000 hours or 2 years of normal use--if no blinking lights suspect the lamp first.

Will not come on.


That's along time for an HD set. usual life spam is 3 yrs. The blinks are an error code. Check your manual or contact a service center to find out the cause of the problem. Usually a power supply issue.

My Sony comes on then both sound and picture goes black.


After being on a little while, the screen goes black (no audio as well) for 20 to 30 seconds. Green light stays on. Then, picture comes back on and takes a couple of seconds to get up to full brightness. About 5 seconds or so after the video comes back, the audio returns.

Until this morning, has only happened a couple of times a day, now happening more often. About 3 times in last 20 minutes.

KDF-E55A20 is about 3 years old.
