i gave my monitor for repairing in my city but he couldn't found exact

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
when i interchange the board the problem is also interchanged.

Re: problem in sun GDM 20E20 Monitor
It may not be the chip. You should use a scope and follow the video process
path to determine where the failure actually is.
In most of the Sony monitors, there is a main driver IC on the video board
that is on the CRT socket. There are also other devices that can cause this
type of fault.
