HOW TO FIX MY JVC TV

I would guess that the top and bottom of the picture is pulled toward the center of the screen as well. This is a convergence problem. If you can solder, you should be able to repair this yourself. If you wish to attempt this repair, please update this and I will provide more details and instructions.

Thanks,

No you cannot! There is a switch on the convergence pnl for complete convergence. You can make things 10 times worse if you don't know what your doing.

Projection TV sets have two very common problems. One is convergence ( 3D/Warped video) the other is CRT fluid ( Dull Video). Below are more details for both items. Also, complete repair kits with instructions and repair support are avail from site such as www.TvRepairKits.com Common Problem #1) Convergence has gone outProjection 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. The power light will blink. TV may also make a chirping noise.
