Sony KP-57WS510 red light blinking 5x

power light if it shuts down should blink a error code--count the blinks and a pause?


SD TECH

It is rear projection TV that use 3 picture tubes of red-green-blue to show color picture on tv front screen.
Do you see standby red light blinking when TV shuts off after showing blue image for a while?
If red standby light is blinking, please count it how many times it blinks, there would be 3 seconds pause between blinks so count pause to pause and post it here to find out possible solution.
Thanks.

hello. problem with the audio (AUDIO), unit goes to standby and blinks the self-diagnosis code. Check IC406 audio amp, PS401, and 402. On some projection models of Sony TV sets, this code means that T8005 (flyback transformer), or the associative components in the high voltage circuits are defective on the D board.

when it goes green, your green picture tube is shorting out, replaceing the green tube costs alot of money. these sony's had alot of bad tubes, the red and blue are probably going out too, it will cost alot to fix this, at least $500 even if you find good used picture tubes to put in it.

5 blinking lights IS the lamp board, part # 1-468-927-12

5 times blinks is error code for No Good White Balance and you said that picture is very green.
As you know TV is approx 7 years old so it needs RGB gain adjustments.
If you are TV tech person or know about TV repair, let me know to guide you further. Or contact local TV repair shop to fix it.

or a new lamp. you could first replace the lamp.
the screen might work fine for a couple of seconds, but then it fades away or deteriorates. This means the lamp is going bad.

tv comes on then turns blue at that time it shuts down. The power is on and then it blinks 5 times!!!

Sounds like bad tuner ( it is soldered in ).
I will research part numbers when i get to work today....T.
