problem in sun GDM 20E20 Monitor

i hv two Sun GDM 20E20 . some time it got the problem when it was
running. suddenly red color got off. now the only red and green color
comes in screen . in second monitor there is only red color .plz
help me wht may be the problem??

i hv checked for cold solder but i hvn' found any cold solder .
i gave my monitor for repairing in my city but he couldn't found exact
problem in it .
he told me there is problem in color processing IC. but i don't know
which IC processes the color.

I think tube is ok bcoz i hv changed the board which connected to back
of tube.
when i interchange the board the problem is also interchanged.

Can any buddy tell me which IC may be faulty

thanx in advance every buddy
