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

1 Answer

TV does not turn on

Hi Techman, We noticed a "sparky" sound coming every 5 minutes from back of the TV yesterday, and then today when we were watching a show the TV turned off. Now when we try to turn it on, the standby light blinks 7 times, there is no picture but sound is okay, then the TV turns off and the light blinks 3 more times. Looks like it is a common problem with Sony TVs, is it fixable do-it-yourself or do I need a Pro? Thanks Fixy

* Most common would be a couple of capacitors in the power supply that are not letting the proper voltage to the lamp.
* The lamp itself is not working properly.

No Picture

Did you have color problems in past? Most of these sets have convergence problems. Amps goes out. But you should have seen some type of distortion from color, red,blue, green. If no color problems then maybe vertical ouput out or horizontal output bad.

Power light flashing/ no picture

I have the same problem. The only way to get the TV to come on is to unplug it, but once you get it back on it turns itself off again in a few minutes.

Hitachi 51F500 (Two separate problems?)

My guess is that the sound you heard was that of some High Voltage discharges that could have fed back and damaged some semiconductors including the microprocessor itself. Since it could be a very expensive repair, I would be very tempted to look around for a new HDTV by JVC or Toshiba. Hitachi has slipped a notch or two in recent years according to my experience.
