Re: I have blue arched lines and blue screen
Your problem is the blue CRT or picture has gone bad, you will need to have the picture replaced, there are three tubes in this model rear projection television. Red, Green, and Blue. Replaceing the blue tube is the only option for normal operation to resume. It may be hard to find the tube, but you can try contacting this website for the part www.vdc.com, they manufacture and usually have stocks of sony picture tubes and rebuilt ones as well. The company's name is Video Display Corporation...

id check the blue screen control first its at the bottom of the set you will have to take the front panel off and behind it is another small black panel remove that one and to select any function those controls need to be attached so slide that front panel to the left there and take you remote put the tv on video input and there are sic controls on this little black screen control block look for the screen controls and turn the blue one just slightly clockwise and you will see the blue screen will light up and you will have little arched lines turn the control back slowly till the lines disaper and the screen goes black
and then cycle the set off give it five mins or so and restart it and see if every thing returns and your video is being displayed then switch it back to your input and view and reassemble
1.) You need to remove the entire plastic piece below the front of the screen. You most likely will find 3 screws on either side in back that you have to remove.
2.) The grill will not come out easy, pull from one side and then when it starts to come loose from the other side(there are several plastic pegs that hold it in.) Then from the bottom pull out( most of these sets have square plastic tabs at the top that tuck in.)
3.) With the grill removed locate the inspection plate behind it (it usually has 6 screws.) You will have to tilt the grill to the left and on its side as several cables are connected to it--they are held in place with trash bag like ties that you can release to get some room.
4.) With the inspection plate removed you will see a fairly small (about 3 inch square) BLACK PLASTIC BLOCK WITH SIX CONTROLS-usually they are marked with whiteout so someone can tell if they have been adjusted.
5.) You need to look very close at the block with a flashlight----usually the top three controls are FOCUS--don't touch those. The lower three are usually marked Screen and if you look very close you will see b, g, r(blue green red)
6.)Usually the blue will be on the bottom left--it does vary
7.) Once you locate the BLUE screen control have the set on and turn it down--if the set is shutting down you may have only a few seconds to try to turn it down---usually to the left with the Blue Screen control.
8.) Best way to do this if the set is on is on a video input with nothing connected--you turn the blue down until the set stays on and then very slowly turn it up until you see a slightly blue screen with or without diagonal trace lines----if you get it to turn on this way turn the blue screen back down slowly until the blue screen and trace lines just disappear.
Let me know if you get it to work--Like I said if it is shutting down you may have to slowly turn the blue screen down a few times to get it to stay on.
I do this here for free and if this helps you at all give me a vote here--it costs you nothing.
Open up the front of the set by removing the speaker screen and the black piece of particle board. on the bottom right you will see 4 knobs. Turn those knobs slowly till the arcs go away. The 3 knobs on the bottom are for color. the 3 on top are for the focus.
the problem, lies on the flyback ,, on the flyback there two adjustment, the screen and focus that was writtten , adjust only the screen slowly untill screen of your tv back to normal.....fading because over saturation of voltage, adjust the screen trimmer counterclocwise....
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
Now Degaussing and convergence are two different things, if you say its degaussing then you should have just a color differential in a certain area, meaning the color should not be arched, everything that passes through should pass throu only with the changing of color. Now if its a convergence the the color may lift upward in an arch, likely separated from the other colors, Red, Blue,or Green. So now which do you think you have? Deguassing usually give you a highish green color or yellow
sounds like bad CRT, some of these sonys have had defective CRT issues, usually all will come and go sooner or later (all 3 bad), you can pull the speaker grill off(either 2 1/4" screws on bottom or 6 1/4" on back sides) and pull off the Crt box cover (2'X3' piece) and lightly tap the CRT's with tv on, if they flare or get colored streaks in pix they are bad, CALL SONY 800 # and complain, also could adjust G2 (Screen control for color) for short patch. Will need new crts.
