Talk to JVC as I have suggested and this is likely a known problem: loss of any color, picture upside down etc requires a upgrade to correct and I have seen about twenty sets with their name like this with this kind of problem.

All projection TV sets have two very common problems. One is convergence ( 3D/Warped video or dead set) the other is CRT fluid ( Dull Video). Here are more details and solutions for both.

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. In some cases the TV will also not show any video. 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, wavy, or has a shadow or shadows
  • 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.

Red convergence will not line up on my jvc 56 inch i art projection tv model # AV-56WP74. PLEASE TELL ME WHERE CAN I BUY THE KIT SO I CAN FIX IT MYSELF!!!


You need to pull the front grill cover/panel off the front of the tv. Remove screws (4) from back that hold it on, also 2 small ones behind front video input door. Then remove access panel. The ckt board closest to you is the convergence amplifier board. You should replace both amplifiers (stk392-110 or 120) and any burnt/open resistors you find near the amps.(use the same value resistors as the corresponding resistors in the blue amp ckt)

Horizontal Lines


The unit most likely has a short in the horizontal section and would require repair by a service center. Go here to find a JVC repair center in your area http://maps.jvc.com/cAscList/
