This sounds like one of the convergence IC's has cracked loose or burned out, and should be replaced and realigned by someone with experience.

I have small blue dots and a yellow shadow in the middle of my screen


The model indicated uses what is called a Optical Light Engine, it is a very expensive part and likely is your problem---not much else will cause this trouble.

Let me know if you have questions.

Red color alignment problem


1) Whenever a rear projection TV has convergence issues, the
fix involves replacement of both IC's = STK392-110.......sub to
STK394-160E for improved durability...........
2) Soldering only is a temporary "fix" at best
3) Do not allow generic IC's, OEM quality or better = I use
Hitachi brand,made by Sanyo,with no callbacks....
4) Skill level needed = above average,....needs chassis pull...T.

Red and blue overlap shadowing


Sounds like a convergence ic problem, normaly i tell people to replace the ic's but in your case try to re-solder the pins on the ic first, you may just have some pins broken loose from the board. Locate the stk392 ic's there will be two of them located on a heat sink, unplug the tv and get to the bottom side of the board and re-solder the pins. if this does not work, then replace the ic's

This can be the sync wheel assy, failure in the drive circuit for the display chip, or an illumination fault. You will have to give the set out for service.
