Hi
I just got a replacement board for my K7000 that was refurbed. My prior board had a strange rollover problem that couldnt be fixed it seemed. Also the Hcoil was non responsive to adjustment. So basically the screen was cut off about 1/4 on the right side and it rolled over backwards. I reflowed the board tried new caps etc and got nowhere.
I had an arcade tech install my new chassis. We hooked up power yoke wires dag etc. I flipped cab on and started to walk to the back to adjust my screen settings as they were somewhat off and poof, the monitor just turned off. I wondered if I had bumped a power lead or something so I power cycled the neo cab and it came right back on... only to go off about another minute later. The screen looks great when it is on, it just turns off lol.
Anyways I started searching the forums and read about B voltage so I checked it and it would seem mine is around 155V on one lead and 166v on the other. And I am guessing it is going in to HV shutdown?
I guess if I need to send the chassis back I will but wondered if you guys had any idea what would cause this.
Here is a video on youtube I made showing the problem. I show voltages on my multi meter, then go to 6:07 to see it turn off again.

I have my old chassis here still to scavenge parts if I need them.
Thanks
