Our set is showing Yellow and Blue in the upper left corner. I guess it's a shadow effect, almost like a color is missing, which I think would be the Red. Any thoughts on this.
thanks,
Ken

I would check for dust particles before I attempted any type of repair on the unit.
Dust particles will appear as dark spots that are larger than the size of an individual pixel. It must first be determined if the particle(s) are on the LCD panels or the screen.
TV shows large red spot in middle of tv when dark show are on, you can see it more. Now blue spots on upper right side too. Spend way to much on this tv to have these kinds of problems only after 3 yrs.
If you have not already done so go into the picture menu and set the convergence. The convergence is the angle at which the three picture tubes meat at a given distance. The tv will have at least 3 and up to 64 convergence points, and those 64 can be set for all three colors. This can be tiresome but I'll be it will solve your problem. What your trying to do is get the color in the cross-hair so you cannot see the color behind the target. On top of the fine setting for each point and color you will probably have 3 gross adujustments for blue and green and maybe red. These adjustments will affect positioning, like what you are discribing. You should do this at least every month, the thermal cycleing of the lamps is what will cause this to creep out of adjustment.
You need to replace both convergence ICs they are both STK392-110 you can get replacement ICs at the following link with free instalation Instructions with pictures. Here is the link. http://servicemanuals.vstore.ca/
