It's not a question about a TV but for a tft monitor, but you folks may have seen a situation like this and have some ideas:

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.

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 should not that I have another, identical monitor (it was a part of a dual-display setup): If I remove the faulty monitor and connect the good one, everything is fine - so it can't be the PC or the VGA, something has gone wrong in this particular monitor.
