Can anyone (moome?) verify the jumper locations are correct on this board? green channel on VIM went bad after only a few days and I want to make sure this card is good.

My board in the latest version, v3
Ver. 0.2
2009/10/12

JP13 which is on the top left, jumper on pins 1 and 2
JP 15 which is bottom right, jumper on pins 1 and 2

Not sure this helps you.

Cheers
Steve

Does the internal test pattern on the VIM work correctly?
If not, then a VNB may be the problem.
Cables from VIM to VNB also should be checked.

Change out the VIM, if that solves the problem, then great,

If not then look at VNB.

Hope you get it worked out.
Cheers

Drags swap out the SD54001 chip on the vim with one from another VIM or channel and see what happens,
Unless you have a scope and put up the stair step pattern. you should see the stair step pattern clearly from the video output on the SD54001. if not then it might be the CLM pattern generator, but I doubt it.
