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
