Question about Sony KDF-E55A20 55 in. LCD Television

Sony KDF-E55A20 shuts off for 30 seconds, then comes back on for 30 more

I have had this TV for almost 18 months now and about 10 months ago, it would shut off for about and I would turn it back on and it would be OK for the next hour or so. After about a month of this it went away until about 3 weeks ago.

Now it is shutting down every 30 - 45 seconds, staying off for about 25 seconds then coming back on, only to repeat the cycle. I tried to power it down, disconnect from wall etc. but the problem persists.

Help anybody?!

Do just as the others said pull out the bulb and clen the screens on top and bottom of bulb. BUT you can also prevent this from happening as soon the next time. You need to take off the back of your sony tv. On the right rear as you are looking at it there is a black blower on top that is on top of where your bulb fits in. you need a ninety degree phillups head screw driver. take the driver and take out the 3 screws... use a can of air to clean it out... You would not believe the holy hell dust stuck up in that blower!!!! Like I said, take the back of your tv off. If you are not sure where the bulb is once you get it off just turn it on. It's not going to hurt ya. If you are lazy about taking the blower off you can turn it on and shoot the can of air while the bulb is on but you are going to have to take the bulb out ALOT of times to get the dust out of the screens over and over until no more dust collects

The first thing I suspect is the projection lamp. If you haven't replaced it in the past year or two try that first. the part number is A-1085-447-A. Please take a few moments to rate my answer. Thanks...

Unit keeps turning itself off.Sound comes back on a little while after set turns itself back on. Sony LCD model #KDF-E55A20. Help it was just taken out of the factory box six months ago I had it and bought...

This Unit is a LCD Rear Projection and most likely the Lamp is causing the problem. I would replace it with a Sony Lamp only. You can order it from Sony at 1800-222-SONY.
I hope this helps,

TV screen shuts off but can still hear

I had the same problem with mine. I took the lamp out, comes out from the front, and cleaned the screens on the top and bottom of the lamp. If these are dirty, mine were, they are preventing the bulb from dissipating heat. This causes the tv to shut off the lamp to cool it down. Mine works like a champ now.
