Sony Trinitron experiences

My Sony Trinitron was manufactured in 1998. For the last couple of days, every minute or two, the picture goes black for 2 to 3 seconds, then comes back again. Since it is 9 years old, I dont want to invest a lot of money in it if it is something major like the picture tube, but I expected a TV that cost as much as this one is to last longer than 8 or 9 years.

My Serial number says it si a Sony Trinitron WEGA KV-36FV1. Any ideas?

The screen control inside the set may be on the highvoltage transformer or on the crt socket; either way if you can turn it up just a little clockwise and the picture comes up but doesn't look good you are likely to have a bad tube. Or try tapping lightly on the glass neck and watch the picture as you tap. If it reacts to the tap you have a bad tube. but the turning the screen control is the best test. Turn it the other way the picture goes off immediately. bad tube: too costly if it is available.

Screen goes black every few seconds but have a picture


Sony incorporates a video blanking circuit that blanks the picture out when the picture tube begins to get weak. sorry, but short of replacing the tube, there's no lasting solution to this problem. I used to have some success rejuvenating the crt, but I found that it didn't last but a few hours before the blanking circuit starts to activate again.

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.

What`s seems to be the porblem


IT SOUNDS LIKE THE VERTICAL I.C. NEEDS SOLDERING. WHEN IT LOOSES THE PICTURE DOES IT HAVE ERROR CODE 2 ? THE RED LED BLINKING 2 THEN 2 THEN 2. THAT IS LOSS OF VERTICAL. IF YOU SMACK THE SIDE OF THE SET.(NOT TO HARD) WITH OPEN PALM ON LOWER BACK IF THE PICTURE COMES BACK IT IS THE VERTICAL IC THAT NEEDS TO BEE SOLDERED.

Tv picture blinks off and on


The on and off conditions is repairable and is not the tube,you should have it check out for loose conections and try not to use it or it will go bad for good and the repair will become expensive,Check power supply,horizontal driver transformer and crt board,If you are not familiar with tv service be safe and call for help.
