Screen is black, only menu items come up. When they do they do not converge, i.e. each color is projected alone and out of sinc.. Sound is working. Lamps are lit and working.

You need to check the convergeance IC.The IC is mounted on the mainboard It has a big heatsink and labelled STK ####.Before replacing the convergeance IC try to resolder first the pins of the IC both the 2 IC a cold solder on the pins can cause the problem....after soldering and nothing happens then that is the time to replace the IC ...After replacing the IC check for open fico resistors near the IC this resistors serve as fuse whenever the IC is bad....be sure to unplug the TV before servicing to avoid shock!good luck let me hear if you have further questions..please do rate my help!

    I think it is the picture wheel. Give it a check.

  • Sebin Punnacheril
    Sebin Punnacheril Oct 16, 2010

    It is an internal device in LCD/Plasma TV's similar to picture tubes in older versions. Sometimes, it may go faulty due to many reasons, resulting in misconfiguration of colors or sometimes even entire loss of video.

  • Sebin Punnacheril

    If the picture wheel is faulty, simple adjustments won't solve the issue.

  • Sebin Punnacheril
    Sebin Punnacheril Oct 16, 2010

    If it's a projection TV, it might be the picture tube getting magnetized. UNPLUG the TV for over 24 hours. In SOME cases, the tube may demagnetize all by itself. Also be careful not to place any other magnetic or electrical substances (which can cause a magnetic field near it), during these 24 hours.

  • Sebin Punnacheril

    Please look the comment below. If it's a projection TV, it would be a magnetized picture tube that is causing the problem, not the color wheel.

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 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.

Picture Problems: Snow, color, lines


The most likely cause is shorted convergence chips and possibly a few pico fuses.

When its out of alignment the video will look 3-D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired. Convergence problems are very common on all Projection TV sets including Sony,Samsung,JVC,Philip Magnavox,Panasonic,Akai,Pioneer2_bing.gif Hitachi,Mitsubishi,Zenith and others.

Rca d52w19 convergence hell


Did you replace the convergence board or the convergence power supply board? usually one color will be a problem with the convergence board and more than one color means the convergence power supply is the problem. Ebay isnt a good place for boards as you never know if the board is good. You can get the convergence or the convergence power supply boards at the following link along with free shipping and tech support.
