Question about Sony KP-57WS500 57" Rear Projection Television

1 Answer

Blue Flash, TV Turns off.

I have a 57" i got from a friend and it has worked perfect the last few weeks. However when i use the TV for more than 5 minutes, it will flash blue a few times and turn off. Sometimes it will just flash blue a few times and be fine for an hour. Any thoughts?

Whole Screen Turns Blue in seconds....


This could be a problem with the Blue CRT it archs or overdrives intermittently. I would have a technician test the set and give you an estimate - if it's the CRT it's usually not worth repair- but it could be video or a screen voltage related problem. It's worth the estimate.

52'' sony tv rear projection turns blue


it sounds like the blue crt is failing Pull the front off and turn the tv on
When it still has a good picture tap the blue crt
if it flashes blue with lines across the screen then you know it is a bad crt

It might not be worth fixing

Good luck

My tv too had a blue screen problem. Then it started to shut down after staying on for less than a minute. I thought that I would with a huge repair bill but I followed the directions at this link: http://www.somelifeblog.com/2007/06/sony-projection-tv-red-line-repair.html and now my tv works perfectly.
