Samsung LCD monitor repair question

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.
