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?!

    When I power up my TV it come on as designed. But, after 30 to 45 seconds it shuts down, the power light blinks green for a wail then it powers back on. This happens for some time before I shut it completely down. Any suggestions?

    i had a problem with tv going black for 30 secs and coming back on about every 5 min. i solved the problem myself.

    remove bulb and vacuum top & bottom vents ( my top vent was clogged with dust not allowing fan to cool it down , therefore getting too hot and shutting down to cool by itself) i put bulb back and have'nt had prob. since

    The Wega turns off and on. Runs for a while and does it again. Is this the Lamp burn out ploblem they are talking about?

  • kenak Aug 31, 2008

    I had the same problem. The set would go off for 10 to 30 seconds and then start up again. The error codes indicated a temp problem. I took the bulb out, like another user suggested, and cleaned the vents on the top and bottom and this solved the problem. Thanks for the help.

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

How do you replace the ballast on a kdf e55a20

to change a ballast board its a bit of work and a tear down to get it in there . but first lets review your problem .
its cycling off every 30 seconds . id suspect a defective lamp or a power supply problem since it sounds as if the ballast board does fire . that's assuming that you do see something come up on the screen when it attempts to start if a ballast has failed it usually will make a noise or the set would almost go into a shut down . also how many blinks and what order are the events happening ?

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.

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 shuts off and then back on, power indicator stays on steady.

I JUST (2 minutes ago!) had the repair man leave for the EXACT same problem on the same model TV!! All he had to do was take the front panel off the TV (in the front) and clean the bulb and fan. He said that the dust gets trapped in there and makes the bulb power off! $100 service call to clean the bulb!! Now it is working GREAT and has not powered off since! 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.
