Question about RCA R52WM24 52" HDTV Projection Television

RCA R52WM24 52 in. HDTV won't stay powered on

We had the convergence problem where we had the 3 lines in a bowl shape on the screen and 3-d picture. We replaced the fusible link but now our TV will not stay on. We turn the power on and it shuts right back off. We don't know if the fusible link fixed our first problem, or caused this problem, because we can't get the power to stay on long enough to check it. Any suggestions?

    We did resolder the connections when we replaced the fuse but I'm not sure if we did a good job of that or not, we tried to make it look just the same as the the other fuses as best as possible. The led on the front does flash when it shuts down. It wasn't shutting down before we replaced the fuse, it only started afterward.

    We bought our RCA HDTV R52WM24 less than 2 years ago at Circuit City...without the extended warranty. We called RCA today and they referred us to an Authorized Repair Center who quoted us $200-300 to fix the screen.



    The problem with the TV seems like convergence...blurry picture with three line colors in an arc across top of screen. Is the fuse problem that others have mentioned? If so, is it possible to fix ourselves without having to solder? Many thanks for your assistance.

I had convergence problem and replace the fusible link with 125v 400ma. It was working for a couple days until then the TV was shutting off and turning on. I set a little fan back there and it stop the problem. I was able to talk to a RCA authorized tech. He said replace the fl 231 fusible link and DL 231 its a diode that is located to the right of the 3 fusible links between the top link and fl 231 link that you are replacing. He mentioned that the diode when it goes bad it take out the fusible link fl 231, also resolder the flyback transformer. Apparently there was some kind of flaw on the type of solder they used on these boards with a lead free solder.

Sounds like you have more problems than just the fuse.. did you resolder the connection when you replaced the fuse. this is what causes that to happen.. fuses blown for a reason. ussally something is shorted. that particular fuse blows because it is a very small fuse and doesent take spikes in power to well. so when a intermittant connection begins to cause ossillations it shakes that poor fuse. it however sounds like you have more than that. does the led on the front flash when it shuts down.

SOURCE: double vision and no convergence

I have found that fusible link FL231 is the main cause of this problem. It's located by the high voltage transformer and looks like a square coil.
Check it with an ohm meter and if it checks bad, then, replace it and you should not have to realign the convergence.
Any questions or comments, respond to this post and I will reply.

SOURCE: RCA R52WM24 52 in. HDTV convergence IC location

the rca itc222 chasis uses no stk the convergence is controled with transistors... the convergence amp board is located above the main signal board(green board)... it can be identified as the one with several heat sink fins on it. FL231 is related to convergence.. there has been a problem with this fuse when it blows the processor doesnt know it is a projection set so it turns it into a regular tube tv. Here at the shop we have found number one reason this fuse blows is poor solder connection on the flyback. So replace the fuse and reflow the solder connection on the flyback and around that area also the horizontal transistor and then see if that doesnt fix the problem.. if you have an more trouble ..... willie@fordtv.com

You can download the manual here. Insrtuctions for auomatic convergence are described. I copied the instructions below.

Automatic Convergence
Your HD Monitor’s picture tubes might have been disturbed during delivery or
after you moved the HD Monitor, causing the color in your HD Monitor to be
out of alignment. The colors adjust by starting auto convergence.
IMPORTANT: Auto convergence works best once the HD Monitor has
warmed up for at least an hour. If you've just unpacked your HD Monitor,
it's a good idea to repeat the Auto convergence function when the
HD Monitor's been running for at least an hour. See page 38 for more
information about Auto convergence.
1. Press OK to begin auto convergence.
2. When the auto convergence is complete, the Red center convergence menu
appears. The cross in the middle of the screen should be yellow. If it is not,
use the arrow buttons to move the red cross to overlap the green cross.
Press OK when adjustments are complete.
3. The Blue center convergence menu appears with a cyan cross in the middle
of the screen. If it is not, use the arrow

I HAVE AN RCA HDTV MONITOR TV THE PICTURE LOOKS 3D AND THERE ARE THREE GENTLE U SHAPE LINES AT THE TOP OF THE TV .IS THE TV SHOT/


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.

42d3683.jpg

7859b01.jpg

e87380c.jpg
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

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.

tHIS is a convergence problem.. first question if you go into the customer setup menu. is the convergence option listed? If you have not got that option i suggest you read "the fl231 problem in the tips and trick section of this website. this can be a simple inexpensive repair..if you do have the convergence option then it can be one of three diffrent boards convergence power, convergence amp or small signal board. and will need further trouble shooting

Rca rear projection hdtv lost color convergence


Projection sets have two very common problems.

The first common problem is convergence


These sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the picture to look normal. This is called convergence.

When its out of alignment the video will look 3-D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the 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, Samsung,JVC,Philip Magnavox,Panasonic,Akai,Pioneer, Hitachi,Mitsubishi,Zenith and others.
You can get more information and a DIY convergenece repair kit with instructions from the link below.

Here are some of the most common problems with these sets...

*Screen Looks 3-D
*Colors wont align
*Screen may look distorted or warped
*No Audio/Video - TV Shuts down - May also make a constant chirping sound

Problem #2 - Another common problem is dull or washed out video.

Your set may have one or more of the following symptoms....

*Dull looking picture
*White looking picture
*Halos around objects
*Red/Orange looking picture

Distorted Screen for RCA HD56w66


convergence is the problem. first question do you have convergence in the customer setup menu. if you do not it could be a special small fuse if you do have "convergence" in the setup menu then you most likely have a convergence power board issue. and generally they are replaced. in our shop such board replacement average 124 labor and about 100 for part. if the fuse bout 15 for part and 80 for labor. there are solder connection that cause the blown fuse
