Weird output from Acer 19" monitor, OSD works fine

[tftproblem1]

I don't really know how to describe what happened to my monitor, but I made a small video here: http://www.youtube.com/watch?v=Gjh5crE-Zx4

In summary, the output of the monitor is all garbled, but still there (not dead) - but the OSD works fine.

I have some knowledge of electronics - so I opened it up, checked the capacitors, didn't find anyone gone bad - but I'll check again, might have missed something (not very experienced in this).

Any pointers as to how could this happen, and where should I focus my investigation? I guess it's something related to the VGA input, but what could it be? (So I should check only the vga board, not the power one?)

[I already have another identical monitor which works fine, so making this work is not critical, nor do I care about the cost so much, I just wan't to see if I can fix it!]

If signal is within specs, try re-seating LVDS cable ends. Otherwise scaler board.
