I have a Sony KP57WV600 that I bought 4 years ago. It started just showing blue arched lines when the picture was dark. Now when you turn the TV on the picture is fine for about 2 seconds, then the whole picture turns blue and gradually the picture starts coming back in. When I contacted Soundtrack for their advice, they told me it does not sound like a bad tube b/c the picture would not come back in. What do you think? Would the repairs and labor cost be worth the repair? I paid approx. $2700 for the TV.
I had the same problem with the arched lines on my KP-57HW40 for a while. Then, slowly the screen turned blueish/pinkish and one day the set just shuts itself off. Sometimes, it's fine then gradually turned bad. I got it in '02 for $2,700. Some Sony licensed repair shop said it'd cost about $600 to replace the bulb if it's found to be necessary. I was just so tired of this chunky junk that I gave up and bought a Samsung LCD. Now, it's sitting in a room waiting for a willing taker.

Sony TVs has an Optical Block issue. If there is an issue with the optical block, then there will be green, blue patches or tint on the TV display. Try resetting the TV to the factory settings and try Power resetting the TV. Turn Off the TV and remove the power plug from the wall outlet for 1 minute and reconnect it and check the operation. If the issue still persists, then TV may require service. You can contact the Customer relations team and check for the available options. Sony had repaired free of cost for such issues. Hence, contact the customer relations.
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...
Had this problem bout 2,3 years ago...it was fixed in about 5 minutes with the help of this article
Tonight I have to do this fix again..the blue lines came back about a week. http://www.somelifeblog.com/2007/06/sony-projection-tv-red-line-repair.html I strongly urge you to save the web page locally on your hard drive or print it out and place with the tv manual....
Sounds like you are describing retrace lines that could indicate that your CRTs or something in the drive circuits are bad.. Check the resistors on the CRT sockets to see if they are in tolerance. If they are try turning the red and blue screen adjustments down just a little this should take the lines away. You will however be needing service in the not to far future. Turning the screens down should help if the resistors check out. Let me know if you need anything further.
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.
they gona get worse to dead circuit, a small capacitor (problably in the neck board) is bothering you, get a tech now that he can see the problem, gonna be cheaper now....good luck
ps some times the picture say to the tech was going on
