    Ours is also a Sony wega (48"?), and just started cutting out completely every few minutes 30 minutes before the inauguration! It comes back on after about a minute, but the on/off cycle is growing shorter as the day progresses. Any other possible causes besides the circuit board as has been suggested?

    Sony Trinitron KV 32FS13 32" WEGA 2001 TV.About 2-3months ago it started out slow to warm up w/picture blinking on/off continually for approx 1-2 min. gradually took up to 8 min to warm-up, picture quality degraded in color/clairty and would periodically blink off/on until now-it blinks off/on every 1/2 to 1 second! HELP ME-it's like torture! Don't want to replace-what's up with Sony's quality? thanks-

My tv cuts off then it won't come back on when powered on the power button light just keeps flashing. After unplugging tv for 20-25 mins it will come back on


CRT screens use a vacuum tubes for displaying purposes. These tubes warn off through time and use, with symptoms like colours fading out, late responce on start and even quit doing what they suppose to do.
My solution is to replace the warn tube with a new one,if you really want to keep this screen properly functional, but this could get to much trouble and cost maybe.

Your TV needs to be repaired. The blinks are a self-diagnostic function built in to Sony TVs. Three blinks may indicate a power supply issue.

Why does my Sony 57" Hi-Scan 1080i? 16:9 Projection Television keep turning itself off. I turn it on and after 10 min it shuts itself off I can turn it back on but the longer it is on the quicker it shuts...


Sounds like a heat problem. Check to make sure that if it has a internal fan that it is working, and clean any dust build up, most projection tv's have fans, usually the number of flashes indicate a code that repeats.

The lamp light does not have to flash on this set for it to be the lamp, and most likely it is just that, the lamp. These sets when the lamps get weak they will do exactly what yours is doing.
