    I have a KP57WV600. After 10 seconds, the screen starts tinting blue. After about 20-30 seconds the entire screen is blue (no picture).

    When my rear projection tv is turned on, it appears to look fine...after about 10-20 minutes, the screen turns very blue. Is this fixable or is it not worth me hauling this big thing to the repair shop for an estimate?

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.

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.

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.
