Question about Sony KDF-E55A20 55 in. LCD Television

6 Answers

Tv shuts down (no visual or audio) then back on again

I have a Sony KDF-E55A20 LCD 55 in. It seems to turn itself off for about a minute or two, then visual is restored followed by audio a few seconds later. It has been slowly increasing to couple times an hour. The lamp light is not flashing, the light doesn't seem low, and we've had it for maybe two years with no problems.

    Same problem-Picture is fine otherwise

    I have had my Sony  Bravia for about five months.  I have noticed on several occasions that it goes completely black, and after ten to fifteen seconds, "wakes up" such as on a computer monitor that sleeps if not used for a period of time. 

  • dherrera968 Dec 09, 2008

    I have the same problem. It goes black and the audio goes away then it slowly comes back on its own. But the lamp indicator is not on, you still think it is the lamp. Others I have talked to state if it was then the light would be on? I would hate to spend so much and it was only the lamp.

    My kdfe55as20 looses picture for approx 20 seconds then comes back on for 30sec to 1 minute then repeats over and over...I never loose audio but it is so frustrating when trying to watch a show...

  • dsstep Dec 11, 2008

    Same problem. It has been geeting more and more frequent. The green power light still stays solid green with no other indicators lighting up to show a problem. Sony online tech support was less than helpful, after an hour of basic "trobleshooting for idiots" all they said was it needs service. No indication that it could be a weak lamp or anything.

  • sonygadgets Dec 20, 2008

    Exact same issue. Sony help was helpless. Service call is the next step. If any one has a fix please post.

    Tv shuts down (no visual or audio) then back on. Green power LED stays on constant throughout.



    Should I spend $200 on a new lamp?



  • hobes001 Jan 07, 2009

    I have the same issue with my TV turning off for about one min. and will make a soft weaning nose, then picture comes on and sound a few sec. later.  It does it after an hr or more of watching.  


    Is the new lamp the fix to this problem, I do not see a clear answer yet.

  • tlilrascal Jan 19, 2009

    I have the same problem. Has anyone changed out their lamp yet?

  • customstar Jan 20, 2009

    I have the same problem. The fan is working, light goes off and on every couple of minutes, It started doing it a few time every day or so. A red light did come on once and it was a steady light. After turning the TV on again, the light disappeared. Light has been in the TV for 2 years. It is dimmer than new bu no where near being dark.

  • bigbonana Jan 25, 2009

    I had the same problem. I installed the new bulb i got on EBAY for $125- original, not imitation and it came with a one year guarantee! It is an XL-2200. Sony sells them for twice as much. Anyway, haven't had a problem since, and noticed the difference immediately as far as brightness goes- i hadn't realized it was so dim...

  • wallass00 Feb 02, 2009

    My tv will work for about 5 minutes and shut itself down, with the green light staying on. I will then turn the tv off then back on again, will work for another minute and then shut itself off again. So you are thinking that this is the lamp??? Is it easy to install and come with instructions to install.

  • ilker9361 Feb 12, 2009

    I have had the same problem now for a few weeks, tv shuts off then gradually turns back on. Now it wont stay on for more than 1 min. I'm will try changing the lamp first and if that does not work, what else could it be?

I had the same problem. I found that the exhaust/cooling fan was not functioning. I clean it and pressure air clean it. This fan needs to be on when TV is ON and also stays on, for a few minutes after the TV is turn off.
