No power or sound

Sony Kdf-E55a20: Sorry earlier I said that the light flashed 5 times, It's actually 4. the fan does come on when you hit the power button and the green power light comes on and blinks 7 times and then goes to 4 red flashes.

The blinking light signifies to a repair technician with capacitors or circuits are having an issue they can diagnose the problem via the amount of blinks in between pauses however it will require a technician and some specific tools and schematics to fix and it may be cheaper if its no longer under warranty to purchase a new one


Hope this helped

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.

Hopefully it's still under warranty or you purchased an extended warranty. My concern is that it is either a power supply issue or a lamp ballast issue. If it has overheating in the past then there may be other issues going on.
Would suggest bringing it into a good trusted service shop.

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
