Power button blinks 8 times and no picture. Sony KP-57WS510 projection TV

You will have to install a convergence repair kit which will consist of both convergence ICs and the 8 associated pico fuses and the 4.7 ohm resistors will also need to be checked. Your model uses the Sony type 1 convergence kit. If you want to know where you get one they are available from www.tvrepairworld.com they do include the parts and the CD with repair instructions.

Try connecting the TV directly to a different wall outlet and check. If the issue persists, try power resetting the TV. Turn Off the TV and remove the power plug from the wall outlet for 1 minute and reconnect it and check the operation. If the issue persists, then the TV requires service.

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.

Sony KP-57WS510 has 3 layers front screen and I do not know what layer is broken. Part number of all 3 screens are as follows.. count it as front, middle and rear screen layers..

4-090-881-11 SCREEN (57), CONTRAST (KP-57WS510 ONLY)
4-095-924-11 PLATE (57WL), DIFFUSION (KP-57WS510 ONLY)
4-081-950-11 PLATE (57WFV), DIFFUSION (KP-57WS510 ONLY)

Also check HERE for your TV screen.

you will need to replace the two STK392-560 ICs and also check the 4.7 ohm 1/2 watt resistors and the six 3.5 amp pico fuses.

Replace Both STKs convergence ICs big black ics with number on them STK392-560.Parts 1-800-223-3205

Brain Freeze ! Sometimes the microprocessor locks up...
you may need reset = unplug ac cord, wait, then try again..

does the from led blink if so how mant times pause then blink again?

eight blinks means, "High-voltage error" and the probable cause location listed is, "T8005 is faulty (D board)". T8005 is the fly-back transformer assembly.

Most likely a bad flyback transformer....circuit board pull +
