Question about Sony KP-57WS510 57" Rear Projection HDTV

1 Answer

8 Flashes, Changed Flyback... still no good.

Ok, I was getting 8 flashes. When you power the tv on you would hear the sound for a second and it would power off and flash 8 times.

I unpluged the tripler and it still wouldnt come on. Since it wouldnt come on I assumed it was the flyback. I found a company locally that sold tv parts and bought the flyback. Came home and soldered that one on and it has the same 8 flashes. The only thing is that when I got home. I noticed the flyback he sold me had a different part number than the one that came off the board. New flyback is 1-453-285-21. The one that was in it originally was 8-598-955-32. The guy said it shouldnt matter. I am wondering if maybe the new flyback doesnt output the right voltage or maybe there is another problem. I am thinking of buying the whole d board... what do you think?

Try the High Voltage block first. Very common failure.

Sony kp-57ws500 flashes blue, green, red then turns off

Re-insering the flyback wire is usually very easy. Push in and give a slght turn and check to see if grabbed. It sounds as if there is more issues than flyback wire. TV should turn on without one crt connected

Sony KP-57WS500 cutting off

Since you get a picture for a while, it is unlikely to be either the flyback or the horizontal output transistor as those would not allow a picture for any amount of time. You would jsut get the 8 flashes. This sounds more like an over voltage problem that could be in the regulator circuit. I'll look up the service manual on this one and get you more details.

Green Flashes - Shuts off

Sounds like the green picture tube is defective. To confirm you can take the front grille and door off and tap the green tube lightly with something plastic, and not to touch any of the adjustment controls to confirm.

Power on for 5 seconds; can hear the sound; then power off; power light flashes

A 440.00 bill is not unusual for your repair,however, I would ask

some questions-- Why 40. for tax?? On what parts?? What are

the part numbers??  How much for a written estimate?? What

is the warranty?? Otherwise,pursue your solution on FIXYA.
