I had the same problem. I bought replacement convergence IC's, but when i took the tv apart I found a couple cracked solder joints on the existing IC's. I touched up those joints without replacing the IC's and it all works fine. You may not need to replace them.

How do you access the convergence calibration menu on a RCA P52926 Rear Projection TV


Hello
To access the convergence calibration:

Press the MENU button on the remote.

2. Press 3 to select the Screen option.

3. Press 4 to select the Adjust Projection TV option.

4. Press 4 to select the Advanced Convergence option (the
Advanced Convergence screen appears).

The green pattern is fixed. The red and blue patterns are adjusted to

the green pattern. The Red Convergence appears first by default.

5. Colored cross-hairs show the current adjustment position on the

grid. To move the cross-hairs to a different position, use the

CH+/- buttons on the remote to move the cross-hair highlight up

and down, and the VOL+/- buttons to move it right and left.

6. Use the arrow buttons to adjust the red pattern. Each press of

the arrow button makes a slight adjustment from the center of

the cross-hairs - you can press and hold the desired arrow

button to make a faster adjustment, and then make fine

adjustments with single presses of the arrow button.

7. Press the INFO button to switch to Blue convergence and follow

the steps above to adjust the blue pattern.

8. Press OK to exit. You will be asked if you want to save the
adjustments

Yes Saves adjustments.

No Returns to the Advanced Convergence screen allowing

further adjustments.
Clear Exits screen without making any changes

Note: Before you use the advanced convergence feature, you must
complete the previous steps to align the tubes

I have some distored blue color across the screen


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.

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

Mitsubishi WS55859, was getting 2 and 2 blink, replaced the pico fuses and convergence chip - 3 times, each fix worked better than the next but evenually failed - now have it working, trying to adjust...


The most likely cause is shorted convergence chips and possibly a few pico fuses.

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.

Cannot adjust horizontal blue convergence on WS 55857


You still have bad grounds on the ICs. Or maybe the solder has fused another pin. If not bad grounds on the ICs you have missed them elsewhere...Really concentrate and look for these bad grounds and check your caps with a cap check. And power resistors too!!!!!

Sony KP-53XBR45 convergence


Hey, found the problem. Your Convergence IC chip went bad. Buy one at Bluestar International Components (bluestar-online.com) - order part number STK392-010 for 6.99. I've read that there are two in the system and replacing them both at same time is a good idea...so, order 2. Now, if you are handy, it will require you to open the back of the TV and solder out the old chip and replace with new. If not, then you might as well call a TV repair person and have them fix. However, every place I've called works on a minimum fee for "large screen TVs" - the cheapest I could find in Atlanta was $399 minimum service fee. So, I'm going to risk the home sodering job .... it's a 10 year old TV and as good as it's been to me, if I screw it up, I feel I've gotten my money out of it. Good luck with your repair. My parts are on order.
