    Video signal drops off, audio signal continues. Video goes black but can still hear the sound from the program. Video is out for about 30 seconds and comes back, first dim and then a second or two comes back to normal brightness. Talked with Sony customer service to helped me with the problem, they helped me reset tv to factory defaults and this did not solve problem. I specifically asked if it could be the lamp. my tv is also about 3 years old. The rep said if the lamp replacement light is not on, it couldn't be the lamp.

    I have the same problem - The black screen happens about every 30-45sec. I called Sony and they refered me to a repair shop. About a weeks wait, and 60 dollars to look at the t.v. There has to be an easier-self fix to this issue. It seems to be somewhat common. My lamp light is not comming on, so what's the issue here?

Thanks for updates.
Its time to replace Lamp. Please buy original Sony Lamp for Sony TV and avoid aftermarket or compatible parts for good performance of TV.

You can purchase original Lamp form Sony Accessories Store. Just type TV model in search box and see details by click search.
Good Luck

Sony KDF-E55A20 problem: picture goes intermittently black and no sound. Green light is still on. Just started to happen. Is increasing in frequency. Not sure if I hear the fan working or not.


Same thing happened to me. If you shut it right down and then start it back up do you get 5 red flashes? if so then what I did was replace the lamp as it was real old. This took care of it.

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.

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
