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.

It is alignment problem & needs lot of patience, expertise to align LCD panels. To align slightly loosen the screws on red & blue panels. Switch on the TV with input source as computer as it has steady graphics. Align for red & blue by slightest movement using light taps with screwdriver sideways. When you are satisfied, tighten the screws. If it is one pixel height line, just neglect it. That much error can be expected. WARNING: If you are not sure, do not carry out the alignment. Otherwise it will go more out of alignment.
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.
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
