Most likely - the CCFL backlight is not getting the power it needs to come on. You can verify by shining a light on the front surface of the set - if you can just make out a dim image, then that is it. On some sets, the CCFL can be seen through the vents on the rear.

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.
