I have a WG 25K7000 chassis that I am having issues with. It has a weird brightness flicker, a rolling shadow in the vertical plane, and the vertical size is rolled over and doubled it seems. I replaced all the caps, and it got a new HOT (because I stole the other for another chassis). The flyback is the good black knob style. It also has some typical weird K7000 hacks. There is a little add-on board on the top of the frame next to the flyback. It has a red wire that runs to the center leg of the hot, down through the hole in the chassis in front of that leg. Wonder what that tiny board is for....

Anyways, can anyone identify my issue? Adjusting the holds and the 50/60 pot do nothing to this issue. I suspect IC2.

Here's the video of the issue.

If this is what you're talking about when you say a little board:

Then you are trying to display a standard-res game on a medium-res monitor. The little board on top of the left frame is only there on the med-res models...
 
Yep, I think that is the board. This chassis came in a Skin's game, which is standard res. Anyways, I figured out the problem.

I fixed my other 25k chassis that was in HV shutdown. After putting it back in (and having a wonderful picture) I swapped out the remote boards. Sure enough, my perfectly good chassis showed the exact same symptoms. Tested the pots and found the Vhold was dead. Tried to remove it and it just fell apart.

Soo.... anyone have a spare 500k pot they can sell me so I don't have to get raped with minimum shipping charges?
