Question about GE 46GW945 46" Rear Projection Television

Fuse blew. Convergence messed up - No menu option. GE 46GW945

The (5A) fuse failed while the set was on. I replaced the fuse and now the convergence is all out of alignment. Menu option to align no longer appears. I tried unplugging for 24 hours - no help. Other posts talk about replacing convergence IC's and/or power supply. Is this a costly repair?? What is involved? Soldering or pop out/in? Shoud I consider setting the TV out with the garbage or salvage it?

I can't find auto converge choice in menu of rca 52" rear projection tv.model # R 52 WH 74.

You have 3 pico fuses by your fly-back transformer. One of them blew that controls your convergence circuit. Your TV now thinks that it is a Basic CRT set with 1 tube. Find the bad fuse and replace with a 1/2 amp pico fuse, and re-solder all the pins of your fly-back transformer. Your menu should have the convergence option again.

Convergence Issue for RCA R52WH76...

Please check the fuse again. Do not just pop the cap off and visually inspect it. Even if the filament appears to be intact, it's probably not. Like ctf1800 said, it's the fuse.
You need to test the fuse for continuity.
The problem that you explained is due to the blown fuse. There are no convergence IC's in this set. I'm am 99.9% certain your fuse has blown.
Get the fuse here:
After you install the fuse, you MUST resolder the points at the flyback transformer which is located next to the fuse (red wires leading to it). Cracked & cold solder usually develops and will cause FL231 to fail again if you skip this step.

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.

Setting convergence using service mode on the tv.

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 projeciton 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.



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. And you should be able to get the grid straight.

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 fix


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 are handy and can follow directions. You can get complete repair kits from or click here. They have put together DIY repair kits that include the OEM parts and step by step photo instructions for each repair. If you are not handy or can't follow directions we would suggest calling a shop.

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.
