Sounds like it is most likely the convergence power supply board, if it were just one color It would most likely be the convergence board itself

    the convergence board has about 12 transistors mounted on heat sinks all next to each other the convergence power supply is the other board.

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

How do I adjust the convergence properties on an RCA rear projection tv?


Normally on the RCA rear projection TV's you would bring up your menu and choose the Setup menu, then press OK on the remote. That menu would then have Convergence as a choice. Once that was chosen the next menu would give you the choice of either letting the TV run it's own Autoconvergence program, or you would select either Red or Blue convergence.

Choosing Red Convergence would bring up a Yellow cross-hair in the middle of the screen. If the Convergence was not correct you would see separate Green and Red cross-hairs. Once they were perfectly aligned you would again see one Yellow cross-hair.

Choosing Blue Convergence would bring up a Blue cross-hair in the center of the screen. If the alignment was out you would see 2 Blue cross-hairs. Using the Up and Down and Left and Right cursor keys you would adjust the alignment until a single solid Blue cross-hair was in the center of the screen.

I have an rca model hd52w67 tv and there is a problem with the picture. the picture has a red and green picture that don't allign by about an inch. I think it is in the picture guns but i cant find a...


Do not align the guns! they are located facing up toward the mirror; they are picture tubes! covered with big glass lenses! heavy!
instead look for a red/green/blue adjustment knob on the set's front; the buttons should say: convergence or, crosshatch push the crosshatch button: once you have three vertical lines crossing three horizontal lines; just merge them using the other R/G/B knobs untill you have one white vertical line and, one horizontal line crossing in the center of the screen.
(you may have to find the controls on the remote using "setup")

55 inch mitsubishi rear projection tv red lamp out of adjustment


Have convergence IC's replaced. I believe this unit uses STK-392-570 convergence IC's Only one has gone bad but replace them both, because if one has failed then the other is not far behind, for Blue and Green. One handles Red, One handles BLUE and Grn. There are only two of them in the set, They are the two largest IC's in the entire set.

Needs convergence amps replaced. Sometimes resistors burn and need to be replaced. This repair requires soldering/desoldering equip. and a trained eye, but usually can be done for 175.00-325.00 at a reputable service center. Good luck, Russmann.

Blue Projection Gun


It is not the gun ,but the convergence IC that needs replaced providing that you have went into the tv menu and selected convergence and manually adjusted the blue convergence.

You have a componet out of tolerance in the green drive circuits, resistor or capacitor. If you have the service manual you should be able to take some raedings off the test points for the circuit and be able to track it down. I am enclosing a link where you can purchase the service manual for that set for 10.99. They will mail it to you unless you go back to the site and request that they email it to you by clicking on the contact us link. They also offer unlimited free support if you purchase your manual. I am one of their support techs. Hope this helps. Heres the link
