Question about Sony KP-51WS500 51" Rear Projection Television

1 Answer

Three separate images about 4-5 inch apart on my TV

I turned my KP-51WS500 on and all of sudden I see three separate image. Seems the picture is out of sync with green shadow being more prominent. Could it be the problem with CRT tubes again. 2 years ago, I had to replace Red and Green CRT tubes but then the symptoms were quite different; the colors will start normally but would gradually turn green and after about 45 secs it would turn off. This time, I see three saparate images about 4-5 inch apart.
Would could be the problem this time? and how much would it cost me to repair. Can someone guide me

    it seems to be a recent common problem...i read some reviews off cnet.com and someone had said that to replace all 3 tubes, it would cost $1000! that's a bit much. we have a sears tech scheduled to come out in 2 weeks but i dont know if it's worth spending that much money to fix. anyone resolve the matter?

Sony rear projection tv kp-51ws500 no picture. Standby light blinking red 5 times. TV has sound but no picture. Before the picture went out TV was turning green then red and had curved lines going...


Blinking 5 times is a sign of at least one of the three video tubes overcurrenting, which will eventually shut off the image. It happened with me but with my red tube over-illuminating. The solution is to reduce the drive intensity on the offending tube. Remove the front speaker grill. Behind it you will find a panal with 6 pots, these are drive (brightness) and focus for each of the 3 colors. My fix was to turn down the red intensity to zero and (after a restart) bring it up slightly till the image was acceptable, colorwise. I did have to adjust all 3 intensities to get a decient color balance along with the focus's on all three tubes (the drive intensity adjustments will knock the focus out as you go). I used the auto-adjust patterns to focus on, and you may want to use a stationary image, such as a paused DVD scene or a video game, to focus on. I still haven't found a way to clear the error code, but I learned to ignore it. The result isn't perfect, but it's very acceptable and it'll do for awhile (and it didn't cost anything!). Good Luck.

Convergence problems w the color tubes


Press the Majic Focus button on the front. If that doesn't fix it then the convergence ICs may be bad.

The colors are separated. Images are blurry and


Try adjusting the convergence. If it won't move see below- (or hitting Magic Focus for some Hitachi’s)
This sounds like convergence output IC problem. convergence board would have to be removed - remove and replace 2 STK IC's and check the surrounding resistors. Shops usually charge between $200-$400 Be sure to vote/rate me if this helped Thanks!
