T V blinks to black every few seconds otherwise works fine

My Sony Trinitron blinks to black every few seconds. Problem started a couple of weeks ago every 30 seconds and is know down to every few seconds.
Perfect picture and sound, turns on an off just fine. If its the tube is it cost effective to replace or just buy a new T.V..
Thanks for any assistance.

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.

Sound, but no picture. Standby light blinking 5 times


A few weeks ago my set started flashing to a black screen. Now a couple of weeks later, i have no picture, but the set turns on and i have sound. The standby light is flashing. I purchased the set in 2000 so it is seven years old. This is the first problem. Could it be all three of the bulbs? Could it be all three of the bulbs? no as you say that sound is ok that means your power supply &high voltage section is ok. please check chroma ic luminance section or system control section stand by ckt ihanks
