Question about Projection Televisions

1 Answer

Sound stays on picture goes out

My tv is an sony vega kdfe55a20 this has been happening for about 5 weeks now. Out of 16 hours of running the TV, about 1 hour after turning it on the morning it goes out for about 30 seconds, when it comes back on, the picture comes on dimly and then brighter to full brightest of a normal picture. It does this 2 or 3 times at most and then 15 hours later it does this again. This problem is progressing in intervals throughout the day and duration length where now it is happening 15 times a day and for about 1 minute each time.

I want to make sure it is the tube before I purchase. How can I run diagnostics on this to be sure it is the tube and not a fan or other part that needs to be replaced? Also, if it is the bulb, can I purchase just the bulb or do I need to purchase the whole assembly?

    It is not possible to run diagnostics and troubleshoot the problem myself? I am an electrician and can check for voltage and ring things out.

  • lkcwinn Feb 14, 2009

    So, to your knowledge, there is no way to run diagnostics on this model? Is that correct?

  • lkcwinn Feb 14, 2009

    I need to find out the sony troubleshooting page that describes all the LED flashings for troubleshooting, being that my picture is getting darker all the time. So when my bulb does go out, the flashes will tell me something, hopefully.



    Thanks, Larry

It would probably be easier to have someone come out and take a look at it before you go buying parts you may not need to be spending money on. it may be a simple fix for a repairman and not so simple for you...

    you can check all the boards etc but it will be hard to narrow down the problem with so many circuits to check, you might call a repair shop and see if they might not tell you where to begin in any case,, sometimes they will tell you other times they wont

I have a sony Vega 55" kdf-e55a20, It is 3 years old, and now the picture and sound fade away for 10-15 sec every hour or so and comes back! Anyone knows what the problem is?


Hi,
Lamp is getting weak and TV shuts off and turns on itself because of weak lamp in TV that you see picture and sound fades away for some time until TV reboots.
Replace lamp in TV to solve this issue. Lamp replacement procedure is written in user manual and its an easy work.
Please buy Sony original lamp for your Tv safety.
Thanks.

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 LCD Projection TV turning OFF.....help!!!


Look carefully at the front lights. Usually when these sets shutdown they have a blink code on either the standby light or the lamp light. Update this with those counts. In the meantime, you may be seeing a problem with heat. If the lamp area gets too hot, the set will shutdown the lamp. Once the area is cool again, the lamp will fire.

Update this and we'll hopefully fix the both of them.

My TV pictures turns black afetr a few hours but I still can hear sound perfectly!!!


It sounds like your rptv lamp is going out. If this is an older DLP this is most likely the cause. You can get a replacement at www.laptopsforless.com part number BP96-00224J for $151. If the tv is still under warranty, I would have them do it, otherwise replace it yourself. If so here is a link to give you step by step instruction. Please give me a good rating. ;-)
