I have a 2002 Sony KP-57WS500 that occasionly (randomly?) flashes red lines and then goes to a full screen red while giving an electrical "cracking" sound before shutting down. Once shut down,...


Seems like your RED CRT is shorting out or failing. Do you notice any other colors besides just red having problems? The blinking of the red light eight times is a High voltage error. It could be your D board but I'm thinking it is more likely the red crt is probably shorting out.

The tv goes on stand by mode by itself. My 57' sony does not turn on but remains in stand by mode. Blinks 9x then stops, then starts all over again. What needs to be done?


9 blink in your Sony KP-57WS500 shows error / problem in Audio section.

1= +19 volts &-19 volts are shorted by any reason on A and B board.
2= IC708 is faulty on A board
3= PS701 & PS702 (fuse) are open on A board.

Above are possible reasons of 9 blinks.
If you have electronics knowledge and have tv repair skills then check as per above info. otherwise I recommend get help of TV tech person or contact nearest Sony service center.
Thank you.

did you check the huge resistors in front of the heat sinks? If so the next items to check would be the velocity boards that are attached to the convergence yokes on each tube the resistors on those boards could be open as well.

Blinking standby light (6 times)


Sounds like the blue CRT is failing. You might be able to squeeze a little more life out of it by adjusting the blue screen control, but it will fail again very soon and the blue tube will need replaced.
