    I have a 52 inch RCA where I KNOW for a fact the convergence option was there at one time and now it's just gone! what are my options? Is it something we can fix ourselves? I have read other solutions and it has been mentioned of a fuse? My TV is also 2 years old actually Feb of 06 made, everything else is just fine. Thank you for any possible solutions...........

If it is way out, it is more that an adjustment. It takes a crosshatch generator to do the convergence.

Screen looks bent and color is out of line


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.

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.

Convergence problems are very common on all Projection TV sets including Sony, Samsung, JVC, Philip Magnavox, Panasonic, Akai, Pioneer, Hitachi, Zenith, and others. You can get a convergenece repair kit from the link below.

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 - TV may also make a chirping noise.
Here are some photos of convergence problems.

Here is a quick test....

Using your original remote go-to the settings menu then goto the convergence section.

Try to adjust the red and then the blue convergence.

You should be able to move RED and BLUE in all directions - up, down, left, and right.

If you can't move them in all directions or cant move them far enough your convergence chips are bad and should be replaced. This is a common problem.

Note: If you TV has as flash focus or magic focus button only try pressing the button. If it fails to fix the convergence your need to fix it. See below for a solution

You will need to replace the convergence chips and possibly some convergence resistors and pico fuses.
This is a a fairly easy DIY job if you know what you are doing. If you have never done this before we would advise calling a shop or if you want to do it yourself get a complete kit with instructions and support from www.TvRepairKits.com

Color convergence out of wack


A professional tv technician can realign convergence or you can try to manually realign it yourself via little knobs under one of the tvs panels near the lamps.

Turn off your TV. Hold down the Channel Down and Volume Down buttons on the front of the TV. Hold for 8 seconds. The set will boot into the service menu.

I just fixed my convergence issue with this, no parts.

My colors all of a sudden went out of wack


Is there an advanced convergence setup anywhere in the menu where the screen displays a grid? If so, you might want to get into that and move along the grid to each section that looks off. Adjust until the color falls behind the gridline, and move on to the next. It can be a time-consuming process, but should take care of your convergence issues.

Rca 52' projection convergence problem


Its a good possibility that your convergence problem could for now be cold solder connections on the driver ICs on the convergence board. The longer you use it the more of a problem its going to surge those ICs till they go bad and maybe cause other componet falure as well. If your not a technician i would have this set serviced asap before it becomes a major repair Good Luck
