Question about Sony KP-57WV600 57" Rear Projection HDTV-Ready Television
I have a problem with Sony KP-57WV600: When I turn it on there is sound and a blue picture for about 10 seconds then the screen goes black, sound continues ok. There is a red light on the front panel that blinks 7 times. Any Idea what the problem is? I would appreciate any asisstance.
Thanks you so much for this info.
I had the same problem with my Sony KW-57wv600. Blue screen turns black after a few seconds, and then standby light flashes seven times.
I called a local TV technician, and described problem. I was told it would not be cost effective to fix. After reviewing the "simple" instructions given on www.somelifeblog.com/2007/06/sony-projection-tv-red-line-repair.html I figured I had nothing to lose.
10 minutes to remove front panel, a "very slight" turn of a screw, and TV worked again perfectly. I could not believe it!
Thank you so much for your help!
SHAME ON SONY FOR NOT POSTING THIS FIX ON THEIR WEBSITE! SHAME ON THE TECHNICIAN AT SONY WHICH INSISTED A SERVICE TECHNICIAN WAS REQUIRED.
I have always been a fan of Sony, swearing by Sony products exclusively. After this experience, I am now forced to consider some other options when purchasing electronics in the future.

I have a service manual for this TV with all the board layouts and lots of info. I am willing to share if someone can help with this problem. So far I have only been able to determine that I have the same problem, that either
1) a +B overcurrent is detected (IC5007), or
2) overheating is detected (Thermistor TH5002).
