I was changing channels the other day and suddenly the red fell out of alignment with blue and green. It is not evenly out of alignment all over the screen but has a wave effect on the top left side and bottom left. In the middle of the screen the alignment looks ok and in the bottom right. We had this happen a few years ago while the TV was under service contract, however I don't know what was done to repair it. any ideas? The TV has been working great besides this up until now. I pulled the covers today to try to see if I could spot a board cleaner than the rest or something that looked like it was newer in order to get an idea of what was replaced the last time. No luck.

These procedures are from the owners manual, go into menu and then picture quality and then:
The Convergence feature lets you adjust the TV’s three tubes. When the TV tubes’
images are precisely aligned, they create the color images you see on the screen.
Over time, the picture can drift out of alignment (this is normal). If your picture
seems fuzzy or has a yellow tint, using Convergence could correct this
misalignment. Only one convergence is needed for all inputs, regardless of the
Note: Make sure the TV has been on for at least 30 minutes (TV needs to
warm up for best results) before starting Auto Converge or Red/Blue
When you select the Convergence feature, a submenu appears with three options:
Auto Converge Automatically aligns the projection lenses to self-correct
color images. You’ll see flashing squares of color dance across the screen
(this is normal).
Note: After performing auto convergence, use the Blue Centering and
Red Centering menus to fine tune convergence in the center of the
screen, if necessary.
Blue Centering Aligns the blue and green images to fine-tune the picture.
Red Centering Aligns the red and green images to fine-tune the picture.
Note: The ability to change channels is disabled when adjusting the
convergence options. The TV must be tuned to a usable signal to
converge the picture.
With most rear projections there is usually an alignment to do with the set up with your TV. This is so the red, blue and green projectors align together to give the correct colouring. This sounds to me what may be causing the outlining of the blue. This can also make it seem off colour. Look in the set up menu of the tv and see if you can find this alignment feature. Usually a cross will appear and you move a blue, red, and green cross with the arrows on your remote to align over the original white one.
If this does not work, it may also mean that one of your projectors, that is the red, blue or green one may be failing causing the off colouring. Hopefully this alignment may fix it for you.
If constant all over the screen it is the static convergence that needs adjusting.
The green is not adjustable!
Move the red magnets with the blue covered with a piece of card to align with the green and then move the blue with the red covered to align with the green.
Replace the convergence amps and test and replace any or all of the 2.2ohm resistors in the yoke return path out in front of the amps. This unit takes two STK392-110 Sanyo originals, DO NOT GET CHINESE KNOCK-OFFS... Buy them from Acme sales out of Florida and you can be assured they're originals.

You will need to put the unit into wahts called service mode because it will have to totally realigned since you change the whole module you changed the chip that had you stored memory setting for convergence called an EEPROM. here in the shop I would unsolder the old EEPROM and put it on the new BOARD. Also on most models you don't have adjustments for the green you have to move red and blue to match green. Imay want you to describe again to me what you can adjust now with the new board in the unit can you move all colors left right and up/down
