1 Answer

32 inch sony trinitron wega

My 5 year old sony trinitron wega will have a difficult time turning on when shut off for more than an hour. It turns on fine when shutdown for a short period of time but if shut down for longer periods it seems to power up ( as in you hear a high voltage noise) but no video or audio and the standby light flashes 7 times. turnig it on and off about 8 times seems to get it to turn on. It has never not come on at all. The model # is KV-32HV600 The serial # is 8017348

    electrolytic capacitors slowly deteriorate with use and replacing them fixes most waning power supply problems. This is not really a job for someone with no high voltage experience, but if you are nimble enough with a soldering iron, I can get you the service manual and you could do this repair yourself. Just comment back here with what you want to do.

    1. Turn off the television.


    2. IMPORTANT: For a projection television that uses an internal lamp, wait 5 minutes after turning off the television to allow the lamp to cool before continuing with the following steps.

    3. Unplug the television power cord from the electrical outlet.
    4. Let the television remain without power for 60 seconds.
    5. Plug the power cord back into the electrical outlet.
      NOTE: If the television is plugged into a power strip or surge protector, remove it from the power strip or surge protector and plug it directly into the wall outlet. If the issue is resolved, the problem is with the power strip or surge protector and not the television.

    6. Turn on the television.



    Here is a procedure for doing a rest on the TV. Try it also to see if it helps.

Comes on and later goes blank


How much later? The Sony sets have a setting in the menu that turnes the TV off if there isnt' any input, Sometimes this feature gets messed up, and the feature has to be turned off, Check that out and see if that takes care of the problem.

My sony wega keeps cutting off then coming back .


a couple of years old can be a long time:

has the TV been on 24\7

It's the amount of hours that matters..

electrolytic capacitors typically last 3000 to 5000 hours....

Special "long life" caps last close to 7000
but the caps in most consumer electronics, even broadcast equipment 3-5K hours.

Blackout area on screen


Make sure the TEXT and CAPTION options are turned off.

I am not sure about the Sonny's, but on my Toshiba a black box appears when I inadvertently leave one of the close captioning (CC) on for text or captions on (such as CC1, CC2, etc.).
