Question about Sony Grand WEGA KDP-65XBR2 65" Rear Projection Television
I have a Sony KDP65XBR2 rear projection tv. It has horizontal red lines across the entire screen. The picture has also started to oval or egg, the upper corners are starting to curve downward and the lower corners are curving upward. The picture also has borders of black and different colors on the sides of the picture screen. The picture seems to be shrinking. Also, the convergence no longer works. I was wondering if you could tell me how much will it cost (ballpark figure if possible) to get these things repaired. Or if its even worth repairing .
To access the focus block with the screen controls, remove the 2 plugs under the speaker grille. There is a philips head screw under each plug. Remove both screws. the speaker grill is now free. Pull the bottom forward and the grille will come off. The top is just held by tabs behind the screen bezel. Be careful as there is wiring to the grille for video input 2 and the front panel controls. There is a piece of fiberboard held on by 4 screws in the center which was formerly covered by the grille. Remove the screws and the panel and the focus block is right there. Each color is labeled for both screen level and focus. Adjust the screen control of the color producing the lines until the lines just disappear.

I had the same problem with my sony KP-57ws500 rear projection tv and thanks to the thread I fixed it in 10 minutes. At first I thought it was a white curved line but then after a closer look it was a very light green curved line. To solve this problem all you need is a flat and phillips screwdriver. Right below your speakers on the right and left side are tabs. Pull out the tabs and remove the screw on eachside. Once that is done remove the speaker cover. The two screws at the bottom are the only screws and you just have to wiggle the facing off by pulling out and down. You will see a fiber board cover in the middle of the tv, there will most likley be twist ties holding some wires, to make it easier to work remove the ties. Now remove the screws on the fiber board and pull it off.
You should see 6 adjustments screws. on the top for is focus, do not touch those.
Below the focus adjustments are the Red, Green, and Blue. The adjustment is slight so turn the correct color slowly and don't push hard on the screw. I had to turn the green to the left to get the lines to disappear and it was only about a 1/32 of a turn. Very very slight. Good Luck.

This is caused by either a flyback transformer or the IC chip that controls convergence and screen display.
This is not tuneable as a DIY from any external controls It has to be replaced and tested in situ to ensure correct alignment of the display. Don't be convinced that this is just a board swap or DIY project. So many think they will save money by swapping the board, but other elements in the circuit as yet not failed entirely have caused this to occur
Use a professional service to repair it properly otherwise the problems will continue after a time even with a replaced board.

Testimonial: "Great help on the likely cause."
Projection TV sets have two very common problems. One is convergence ( 3D/Warped video) the other is CRT fluid ( Dull Video). Here are more details and solutions for both. Repair kits with instructions are also avail from www.TvRepairKits.com
Common Problem #1) Convergence has gone out
Projection TV sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the video to look normal. When its out of alignment the video will look 3D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the TV menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired.
This is a very common failure on these projection sets and a fairly simple DIY fix. All projection sets including Samsung, RCA, Sony, Philip Magnavox, Panasonic, Pioneer, Akai, GE, JVC, Toshiba, and others at some point will have the same problem.

Common Problem #2) CRT Fluid is Cloudy
Projection TV tubes have a liquid coolant that is used to keep them from overheating. After many years the coolant in the blue and green tubes will become cloudy and cause the screen to look dull, red/orange, etc. You may even see halos around images.
