Re: blue screen.....

You have the classic sign of the failed Sony CRT. This was a VERY common issue with tese series of TV's. Just replacing the blue CRT alone isn't easy as they are no longer available and have to be pulled to be rebuilt. If you do that I highly suggest replacing the green and the red as they will follow. Maybe not now but trust me they will. You are looking over 1000.00 in repairs.

Screen turns blue on my sony KP-51WS500

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.

Blue Screen and TV shuts off

Here's a shortcut to what the blinking codes mean.
Strange how some people have 5 blinks. Most with this problem have 8 blinks (like myself)

I still have the blue-flash-then-shutting-off problem.. (8 blinks meaning voltage error) but I did fix the blue lines.. The lines across the screen can be very easily fixed whether they're blue green or red. . No, I mean REALLY easy. Took me longer to get the cover off. Once the front cover is off it takes 10 seconds. This link was also posted recently in one of the posts below as a solution..
(My lines didn't look like the ones in the picture mine were several evenly spaced blue arcs)

After some research I believe the flash/shutting off problem means the CRT is going. I've also read that it might be the D-board and I'm not even sure that that is... But If it is indeed the CRT then I'll let you know it's very difficult to find a replacement blue CRT as this part has been discontinued.. but I did eventually find an alternate to an alternate part (yes that's the 3rd alternate !)) online for $256. Here:

If you're bold enough to attempt that then good luck and please let us know if it worked.
Or another alternative is there's a whole lot of Boxing Day sales goin' on right now.
