Sony kp-s4613/2 hie I dont seem to find any info on your site on the sony kp-s4613/2, im assume the kp-51 might be close. my sony shows a clear picture for 3 or so minutes then becomes wavey with what appears to be a picture moving diagonally fast to the right the switches itself off, then on again at times! a series of on/off sequences seem to reset it. before it gets wavey the picture starts to blank out while the two red leds in the front alternate on/off then switches off. please help alex

Sony kp-51ws520 when turned on just has standby light flashing . the rest is all dead, no picture or voice.

Standby flashing light shows that tv got some internal problem. How many times standby light is flashing is info that provide info about what section of tv got problem.
Count standby light blinks and let me know, there would be 3 seconds long pause in blinks so count pause to pause.
