You need the small signal board reworked or replaced. It is located in the back left side. Check with PTS electronics at 1 800 844 7871, Have model# and Chassis # handy. They call it the small signal module and I believe this would be correct. This will correct your problem.

I have a Sony KDP-57WS550 TV that has a convergence problem. Based on the symptoms, I'm not sure whether to indict the convergence ICs. In the convergence mode, I can move the red (and blue) crosses,...


With your TV in setup Use a small magnet to "move" the non converged Red, Blue, or, Green color lines "crosses" (each CRT will need to be adjusted in turn) by moving the magnet close to the offending Red, Blue or,Green color CRT yoke or, tube while observing the movement of the CRT color line "cross" in a mirror ( try several places near the tube and, several strengths of magnets:) a refrigerator sheet magnet works well (you can cut these with a scissors to make a better fit or, apply less magnetic "pull." by making them smaller (you may need more than one magnet per tube to fix each CRT's convergence) When you have each CRT tube's convergence right, apply some clear silicone adhesive to the magnet and, permanently affix the magnet to the now "fixed" CRT tube exactly where you placed the magnet to obtain the best convergence on the CRT.
(Do not adjust the "Green" CRT unless you must, as it is used as the color line to adjust other lines to)

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

Seeing a picture like double vision.Tried to adjust the red & green crosses and the blue. The crosses or plus ( ) signs are supposed to be ontop of each other I assume?. What seems to be the problem.


They have to be on top of each other, converging perfectly. If you are unable to align them - you have convergence issue. Two convergence IC's have to be replaced inside of your TV. I would strongly recommend to let it do by professional technician.

The color is off and the figures are outlined in blue and yellow, plus the picture is cloudy looking.


Press menu on your set scroll down to where it says picture then press select. Now scroll down to convergence and press select. A white cross should appear on your screen. Your objective is to merge or converge all the crosses into the one white cross. If done right you should see only the white cross. You may see a little green and blue but don't be to picky. Make sure you read the on screen instructions on how to do this. After this you continue to the next step and you should see several white crosses across your screen. Do a convergence for each one of these crosses. Your picture should brighten up and your yellow and blue lines should go away. If it doesnt you have a bad convergence chip or some bad capacitors. If the first step doesn't fix it I would that you had a tech come and check it out.

Green convergance problem


Sounds like a convergence amp failure. Depending on model, there may be 1 or 2 large Ics. Due to the delicate soldering involved, a tech should change these amps.Often the old part numbers have been upgraded, and small value resistors may need to be changed also.
