I have a Samsung syncmaster 206 BW LCD.
All of the sudden the blue gain seems almost double the normal on analog in.
Cannot seem to be able to correct for it (other then cutting the VGA cable and
placing an attenuator in blue ;-) ).
I do measure nice 75 Ohm terminations, so it is not an open termination.
Has anybody ever opened up one of those, is it one big LSI?
Or is there a chance for human repair?
Else I will have to send it away..... with unknown results.
Googled for an hour, could not even get a service manual, or picture of the inside.

Tried another monitor on the same PC, or this LCD on another computer, just to make sure?

Jup, same monitor on other PC, same problem.
It happened during a resolution mode switch, and it is very very hot here
(for the Netherlands), so temperature may have been a bit too high for it.


Do you have a breakout VGA plug or can you get in the PC and probe? Maybe the termination ain't there when it clicks into the selected mode because some CMOS switch blew?
