KP-57WS520 Sony Projector - No picture

Sony Color Rear Video Projector KP-57WS520. I cannot locate any online repair manuals for this model. I'm in a situation that I need to repair the TV myself. I just need to know what part I need and where to purchase this part. It is a Code 5 according to the "Standby Lite". Any help would be greatly appreciated.

Also, surprizingly, I have gotten picture to come on, but if I shut it down. No picture for a long time period. I have tried different outlets, took it apart to check for bad connections and cleaning. Nothing.

    After quite a few adjustments to the Focus Block. It didn't do the trick, every so often it would give me a code 10. Any information on a code 10?

Hi,
5 times blinks shows incorrect white balance (AKB) error. TV needs Screen Volts (G2) adjustment.
Take off lower front panel, find Focus Block that has 6 control knobs, adjust Screen volts of each CRT (red-green-blue) and problem will be solved.
Be Careful while working in TV.
Let me know if you have further question.
Thanks.

Testimonial: "Unfortantly didn't do the trick, during quite a few adjustments as you suggested, I would get a error code 10. Any feedback on this new code?"

    10 times led blink shows HV protection error that means over current consumption.
    Please adjust screen volts little bit as too much screen volts increase bright picture that shuts down TV with 10 blinks.
