Convergence Adjustment Pattern

When i was adjusting the convergence on my tv my son moved the grid to the left when i step away for a sec. The service manual only tells how to move it to the left but i can't find where it tells you to move it to the right. Is there anyway to completely reset the tv so everything goes back to factory specs or is there a way to move it back.

This was for a similar model.

In convergence mode press 1 for no compensation, 2 for factory default and 3 for last saved setting.


Hope thats it!

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

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

Yes Saves adjustments.

No Returns to the Advanced Convergence screen allowing

further adjustments.

How i adjust horizontal size and vertical size

To answer your concern, all you have to do is to change the setting of your aspect ratio on your TV.

Here is my suggested way to procede:

1. Apply 1080i signal, which should produce an oversized HD image on ColorStream1or 2.
2. Select an HD channel that is broadcasting standard 4:3 image, not wide screen.
3. Switch to the Service Mode ( Please refer to the above links). In the Service mode, press channel up/down to find the Adjustment parameters needed for the following steps.

4. Adjust HIT with volume up/down control for the image height to 22.5 inches.

6. Adjust WID for image width of 30 inches, (22.5*4/3)
7. Adjust HPOS to center the image.
8. Adjust PARA and TRAP to minimize geometric distortion.
9. Switch into Convergence mode and Adjust VLIN to get equally spaced horizontal grid lines.
10. Measure the length of the central grid lines and note the number of horizontal and vertical grid lines. This information is used to create an overlay grid.
11. Create the overlay grid on 40x25 x0.003 inch clear Acetate sheet, which you can get at the Art Supply store for under $2. Draw the grid with a fine line erasable pen. Draw vertical and horizontal lines through the center of the sheet so that the lengths are the same as the central grid lines. Now draw the grid so that it has the same number of lines as the convergence grid but are equally spaced, with the outer ones at the ends of the central lines.
12. Cut off about 1/4 inch from the right side of the sheet so that the sheet can lay flat against the screen, which is slightly less than 40 inches.
13. Put a reference mark on the TV frame 2.5 inches down from the upper left side of the screen.
14. Place the overlay on the screen so that the upper edge lines up with the reference mark. The overlay sticks by electrostatic attraction.
15. Use convergence controls to remove grid distortion and converge grid colors. Refer to the Anamorphic link for details.
16. Enjoy 1080i.

Other Comments:
I didn't realize I could create the overlay grid before placing the Acetate sheet on the TV screen, until I finished drawing the grid with the sheet placed on the screen. I added grid lines as called for in the procedure. I'm sure this method took much longer no only to draw the lines but some of them were difficult to see.

Part way through the convergence procedure, I became concerned that the image width was off since I did my screen adjustment with wide screen image. Thus, I decided to repeat that step with a 4:3 screen.

I confirmed the need to press 7 often to save results since after I adjusted one grid color without it, I accidentally hit a key that switched me out of convergence mode and when I switched back, all settings were gone.

Another mistake I made was not realizing that the cursor color determines which grid gets moved.

I have a problem with my convergence. I cannot get the cannons to adjust with the remote. I have red shadowing around the picture and the adjustment for convergence around the outside of ghe screen wont...

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.

Hi Mike: Can you help me with my Panasonic PT-47WX49E convergence and service mode

Sorry, I have never done that on a Panasonic set so I am not at all familiar with the procedure. I will look around and see if I can find simplified steps.

Do not adjust any knobs as instucted in the previous thread if you TV have a convergence problem. Doing so will only make things worse. The blog does however show you how to fix other common problems with these sets.

Here are some of the most common symptoms and example photos of a convergence problem

  • 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.

You need to replace the convergence chips and convergence resistors. Check the site They have put together a kits for most models. If you don't see a kit for your set send them a quick note and they will put one together for you. Their kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, etc.

Convergence settings

Key Functions
7,8,9 = select R, G or B
+100,0,PRE-CH = mute R, G or B
INFO = test/normal
4 = shifts from point to line, grid move
2 = restore factory
SOURCE = H/V select
ADD/DEL = Save
S.MODE = exit
MUTE = cursor forward
P.MODE = cursor back
Volume +/- = moves convergence left or right
Channel +/- = moves convergence up or down
1 = zero's all convergence settings (ugly!)
U/D/L/R = move cursor
SELF FOCUS = saves the convergence adjustment - do before exiting

Good luck.  I let a sub-standard service joint work on mine - they replaced the OEM chips with a higher wattage equivalent, and I've had nothing but problems ever since.

Yes, you have a size problem you have horizontal and vertical size. Either its' in the service mode or somewhere on the set, with this set it's probably in menu. Must be set too high. I will look for menu codes! Is this an Akai or Panasonic set?
