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 photos of convergence problems

52inch projection screen television has only red and green colors and its difficult to see the picture.

If the picture looks 3d with lines bowed it may be a convergence problem---go into the customer menu and call up convergence and at least look.

On our rca hdtv model # R52WH77.. the tv is having like a 3d look on it and has a bow in the picture.. we bought the convergance repair kit from tvrepairworld.com and replaced the 2 parts it gives us.. ...

have you reset the convergence parameters after installing the kit to fix the option? Usually you will need to reset the defaults to get the outer edges back in alignment.

My Hitachi 57F59A projection tv has a yellow color to it. I have ajusted the color and tried to reset and start over but still yellow. What could b wrong?

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
  • 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 of a set that needs the fluid changed.

The convergence box keeps going out.

this 3d effect is due to what is known as convergence.i work daily on these set in the shop. (thats a good testomony for these LOL) but the first question i ask is 1 in the customer setup do you have convergence option.. Next question is the picture bow tie looking and 3d. if you are missing the convergence option chances are it is the fl231 fuse. then you need to read the fl231 fuse under tips and tricks section of this website. Convegence is controled by three cuicit boards. if any of these need to be replace a technician may need to set or adjust the convergence back to faactory specs
