Projection TVno convergence - 2_bing.gif 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.

Convergence problems are very common on all Projection TV sets including Sony, Samsung2_bing.gif, JVC, Philip Magnavox, Panasonic, Akai, Pioneer, Hitachi, Zenith2_bing.gif, and others. You can get a convergenece repair kit from the link below.

Common Symptoms include....

  • Screen looks 3D2_bing.gif
  • 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 flash2_bing.gif 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

Colors are seperated


This is an ITC222 chassis. Very common for broken pins under flyback to cause this. Resolder flyback and replace adjacent 400ma fuse. It's a little red box, there are 3 in a row and the one that blows is the middle one. If this does not repair, suspect the convergence power supply. It's the vertical board above the power supply. I've replaced the power mosfet on that a few times as well. And remember if there's any doubt contact a professional. Goodluck.

Picture looks like hour glass.


You're probably talking about bad convergence. Probably Convergence power board. Only $20-$30 from encompassparts. com, if still available.

Rca r52wh74 bowed picture and 3 d color


Your convergence amplifier has failed.
There are a few things that usually cause that in that particular chassis design, the most likely one being that you have lost part of the power supply to the convergence amplifier power supply board.
You may be able to repair it yourself if you're good at soldering, and dis-assembly / re-assembly.
Look for a 400ma fuse that's opened near the FBT, and re-solder all the connections in that area. Also check to see if any diodes have shorted around it too.
Good luck.

How do I replace the FL231 fuse on the circuit board, removal and re-soldering I was told this will fix the convergence issue and that the convergence module is not bad.


Yes, but before powering the set back on you must fix the original issue that caused it to open. The high voltage transformer location LL008 will need to be un-soldered and all pins and pads cleaned. Then re solder the pins to the pads with solder. The original solder was lead free but it tended to crack after it heated up thus causing the intermittent connection and then opening the 400ma fuse to the convergence panel. The fuse is no longer available, but I have included a link to be able to purchase it on ebay. Make sure you ONLY use the size fuse needed as anything higher could be a fire hazard. Please take a moment to rate my answer. Thanks...

I had to replace a fuse for the power supply and know the picture is blurry and bowed


Your convergence power supply is propably not working. The convergence supply board is mounted above the mainboard and has AC 110V supplied to it from the main PCB. That's probably why the fuse blew.Rca Has abulletin regarding replacing two diodes CR19710 and CR19713 on convergence power board.

Bowed/Warped picture/convergence problem


There is 2/3 boards on bottom first board to left is the Deflection board next to it is the SSB board it has the tuners and video jacks on it. Deflection Board has 3 fuses right in a roll on right side of FBT Flyback Transfomer (FL231) it will be middle fuse 400ma they do not look like fuses they are small brown rectigular you can pull top off of them with needle nose plyers to check fuses on top.

How to find the convergece amps


On that chassis the only fuse affecting convergence is a 400ma pico fuse near the flyback transformer. If this fuse is open the signal board will never send the "ON" command to the convergence supply so the convergence will be dead.
If the pico isn't open then suspect the amps themselves or possibly an open resistor or two.

Fl231 fuse compatibility


yes, thats the replacement fuse for your set. However unless you have replaced the convergence power supply also chances are the fuse will blow again, as the power supply shorting is what causes the convergence to get out of alignment and it will then blow FL231 thereby removing the convergence option from the menu.

I have a rca hdtv r52wh77 1 year old ,i have color problems ,i cant get to the convergence set up ,please help.thks


Try looking at the main board very near the flyback and you should see 3 fuse links (they look like hard capacitors) one of them is probably open causing lack or power to the convergence board by way of the ribbon seated close to the vertical output IC
