I have #65s500 projection tv. the colors are blurring in the bottom left corner. manually focusing it will not correct it. thanks

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 Symptoms include....

• Screen looks 3D
• Colors don't line up
• One or more colors can't be adjusted when using the convergence menu.
• Screen is bowed or warped.
• TV shuts off after powering on. Power light will blink. TV may also make a chirping noise.

Here are some pics of convergence problems.

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.

lgray1010,

Try using the Flash Focus to/or manually try to dial in the convergence. If you are unable to focus the TV using its convergence adjustment it's time to call the TV repair guy. Figure on between $250.00 and $400.00 USD.

There is a convergence output kit for this set. There are probably resistors in the convergence circuit that are starting to loose there values. If you are going to have the set worked on have them install the whole kit which includes the convergence outputs and resistors. Thanks

Have you tried the "Magic Focus" Button/Option in the Menu Setup Screen? If you have and it still is there, You Have a Burned out Color Tube. It is Cheaper to Throw it away and Buy a New one.
Good Luck..

Your TV requires Geomatirc Adjustments in proper manner by qualified servcie person.

replace the two convergence IC's
Sony convergence problems

out of focus

Check to see if you have it set to do the Magic Focus on turn-off. It is in the menu under setup.

get a shop manual,it tells how to do the whole convergence process and how to store it to the rom memory to save it.
