Re: Sony KP-51WS500


I am not sure what you are asking by a blue video image. For the past yearish there had been a blue tint to the picture when viewing. Recently it got worse--as I stated in the problem, after 10 seconds, the screen starts tinting blue and by 20 seconds or so, the entire screen is blue (no visible picture at this point).

After this happened, I did take the back rectangular panel off to watch the projectors during this 20 second phenomena. When the tv is first turn on the green, red, and blue were on. After 10 seconds the red and green faded out leaving only the blue on (the red and green went dark). IE. the same time that the picture of course turns completely blue.

You have all three projection tubes that are failing. This was a common issue for this year. Depending on serial number 2 of the 3 CRT's (green and blue) are no longer available. They will have to be pulled and rebuilt.

Common issue on this set--locate the master screen / focus block and lower the BLUE screen control until the blue cast is gone, only a slight adjustment will be needed.

I have a Sony rear projection tv model KP-51WS500. It has had some fine green lines across the screen, but today it has started to fade to green after being on for a few seconds, then truns off. Any...

It sounds like the focus pack needs to be replaced (p/n 122392535) and re-adjusted. The re-adjusting could be the tricky part if you haven't done these before.

Sony kp-51ws500...i turn it on and get a blue screen..can hear audio..but the standby/power light flashes then turns off.. count 8 flashes please help..thanks

Sounds like from your description the Blue CRT ( picture tube ) is shorted. I believe they are no linger available. If in doubt, I would call a service company to verify this.
