Blue lines on screen...

You have two problems: blue lines is convergence problem and the blue screen and shutdown is Blue Screen control is up too high.

That model uses three CRTs ( Picture Tubes) one red, one green and one blue. You can get the replacment CRTs from www.tvrepairworld.com

Ur convergence it dead.Do u know how to solders? Tries these websites. Tv repair World.com or Tvrepairkits.com have it.Buy a convergence kit used what in that kit ur tv well get back to normal.The shop will cost u $300 for parts and labors.

First check what color of faint lines comes then reduce Screen Volts in TV of that CRT (tube)
Take off lower front cover, speaker grille of TV, there you will see focus control block that has 6 control knobs, upper 3 knobs are focus adjustment of red-green-blue CRTs and lower 3 knobs are screen volt controls for red-green-blue CRTs. Turn screen volt control knob CCW to reduce screen volts of desired CRT.
Put TV on any free AV input so screen will be dark enough to adjust screen volts.
Thanks.

Just fixed mine with the same problem you all described:

Can be 1 of 2 things. 1st the red tube just needs the voltage to it turned down. In the front of TV (you have to remove the lower front half of TV to access it) is a plastic square with 6 knobs. The from left to right top knobs control focus for blue,green red. The bottom knobs control voltage to each tube in same order (so lower right knob for red) turn SLOWLY to left to reduce voltage until excessive red and lines go away. If you over turn left or right set will turn off. If that does not fix it or if lines reappear then option 2 is that red picture tube is failing outright and needs replacement.

remove the front speaker assembly and the small access panel behind it and you will see a small square control assembly with 6 dials on it 3 control the color guns and 3 control the 3 gun focus. Try turning down the red control slightly they will be set up just like the CRTs red green and blue.

My tv too had a blue screen problem. Then it started to shut down after staying on for less than a minute. I thought that I would with a huge repair bill but I followed the directions at this link: http://www.somelifeblog.com/2007/06/sony-projection-tv-red-line-repair.html and now my tv works perfectly.

I got this Sony KP-57WS500 57 in TV for FREE from a guy posting it on craigslist because he saw "BLUE SWIRL LINES" also knows as "Retrace Line" on the screen and he went to several repair people and got high repair costs so he was giving it away for free, but i found a guide that tells you how to adjust the tv to make the blue or green or red lines go away, aparantly the line show up because the voltage on the color ray gun tubes that get out of adjustment. Here is the Link to the REPAIR GUIDE. http://www.somelifeblog.com/2007/06/sony-projection-tv-red-line-repair.html

Sounds like a conergence circuit failure, probably a couple of AMPs and a few discreet components. Probably 250-300 repair
