Question about Sony KV-32S45 32" TV
9 year old KV-32S45. The picture w/sound has begun to flash off and on when the TV is turned on. Does it on all inputs (line and tv). Picture with sound only, the set power is still turned on. At first it would last a minute or so then stop. It now flashes off and on for over 5 minutes and the flashing is fairly rapid at first, then slows in pace as the set warms. It will then stop for a period, 10 minutes?, and then do it again for a few times before taking another rest from flashing. The picture quality appears to me to be perfect. bright and vivid colors. Just won't hold on. A slight clicking sound goes with the cycling of the picture. Is this a old picture tube going? Worth getting even it looked at? Thanks!
It was the Screen control as I know understand these to be 99.995 of the time (Sorry to say in the first post that sound was on..it wasn't). Turned up the control, easy to get to...just rememeber to unscrew ALL the screws and not yank out the board and it's attached ribbon cables as you remove the back. Problem fixed for a short period (months?) as I understand. Sooner or later the tube gives out and you can't keep upping the power to offset. At that point it is plasma vs. LCD. And to think a TV tech would have wanted $125 for a 15 minute screw allright..LOL Somethings better to do yourself.

Try first to turn down the screen control on the high voltage transformer. If that does not work the picture tube is most likely going bad. Sorry to be the bearer of sad news. Good Luck

I am having the same problem. I took my set apart and cleaned it out real good and the problem seemed to get better. Now it only flashes for about 10-15 seconds and then stops. I am going to search for loose solder points in the next day or two. Hope it works!!! I'll let you know if it does!!

Probably the tv has a loose solder in the board. this is normal especially when tv is aging. most of the components inside are emitting heat resulting to loose the solder. try to inspect and resolder if possible. but if you dont have the proper tools and equipment and you're not inclined with this kind of job, better bring it to a qualified tv technician. good luck!
