    what was the 9.99 for?

  • tif813 Jan 21, 2008

    I have an RCA R52WH74 tv. One of my kids hit it, now the picture is slightly bowed and the convergence is off. The manual says you can access the auto convergence in the setup tab under the main menu. When I select setup, auto convergence is not in the list. When I initially bought the set and plugged it in, it went through an initial setup. At the end it checked the convergence and it could be adjusted. I cannot get back to this initial setup mode again, even after leaving set unplugged overnight.

    I have the same Tv. The auto convergence menu starts but doesnt finish and there is a big black in the middle of the screen when doing this, The colors on the plus are sideways a little when trying trying the red and blue convergence. When not in menu, there are three colors half way down and black above so half the picture is cut off. Is this the convergence board or ajustment of some kind?

    Can I superglue the fuse?

  • jbenedictins Apr 16, 2009

    I was wondering. I have a small fuse for my RCA Projection TV. I have been advised that the fuse must be soldered onto the board or it will simply blow sortly after each time..

    How does one go about soldering the fuse in? It dosent look like there is room to do on the board..

    ANY help would be amazing!!

    I have a convergence problem on this set also. The picture is bowed at the top and bottom and the colors are seperated. We get three pictures in green, blue, and red shadowing on top of each other. I replaced the convergence board and this didn't fix the problem.

    Is there another place I should be looking?

Convergence in this unit can be one of 3 possible boards. can you adjust any the crosshairs move in customer setup convergence menu

Posted on Jan 18, 2008

  • Willie Howell Aug 30, 2008

    convergence is a very common complant in this set. and can indicate one of 3 boards. the first question is always is the convergence option in setup menu. if it is this means you have a very common problem known as Fl231 fuse. I repair alot of these at the shop it is a simple fast inexpensive repair. if you know how to solder. faulty solder connection causes vibrations in this very small fuse and blows it you have to put some more solder on the flyback transformer joints when you replace this fuse

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

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. The power light will blink. TV may also make a chirping noise.
Here are some pics of convergence problems.

What you will need to do is convergence. You can get a repair kit from . It includes replacement parts,step by step instructions, support, etc.

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.

What you will need to do is replace the coolant and clean the crt. You can get a repair kit from . It includes replacement coolant,step by step instructions, support, etc.

I have the same RCA (R52WH74) on a ITC222 chassis.
Same convergence problem (RGB color separation on image - lost convergence option on Setup manual). Sucks because mine is 2 month out of warranty and RCA is not helpful.
There is a site where I am getting excellent help and the also have the parts.
I would suggest that you go there and email Sonny for assistance.
Good luck.

Rca r52wh74 - no auto convergance

The model number of your TV probably falls under the ITC-222 chassis design. Do a search based on that criteria and it should point you in the right direction. If I remember right, you need to replace FL231 on the deflector board though. Good luck
