Kaneko Super Nova RGB alignment problem

[mesmer]

Hi All, I recently got a Kaneko Super Nova board, and the red is not quite aligned with the other colors:



So I checked out the video area of the board, and I See an extra resistor on the red circuit. I colored over the traces to help follow them (the unedited photos are in the album)




Has anyone seen a grid of solder pads like this on the video section of a board before? What would this be used for? I'll probably remove the resistor on the red trace, and see what happens.

Had no idea a resistor could do that to convergence. Did you tried other boards?

You can always remove the resistor and put it back if nothing changes.

Still think this is very strange, i wait for some of the more knowledge members to post their opinion. Good luck

Did you try removing the resistor?

Not yet, maybe this weekend.

I checked, and my Super Nova doesn't have any sort of resistor there.

That sure look like a mod done locally by the operator who last used the board. Just bridge again the jumper trace which got cut to make the resistor effective. That will cause the resistor be ignored by the circuit. If it has no effect you can just remove the bridge and go back to the original state.

The resistor is bizarre, but all it might do is add a TINY bit of capacitance. That, however, would make it slightly less defined, and would make it delay a little to the right. If red is appearing first, your problem looks more like green and blue are delayed behind red. A passive component (RLC) won't make the video signal lead the other two like that.
