I am at a bit of a loss on what to do here, so I am hoping someone else here may have had a similar issue. I recently put a new main driver / gi board in my ST:TNG and after about 5 minutes of playing all of a sudden all the pop bumpers activated and stuck on. I thought maybe the board was bad, so I went back to my original board, and anytime the 50v rail gets power, anything attached to the orange/purple lead shorts on.

It doesnt seem to me that there is a bad transistor, or anything of that nature, since two different boards are having the same issue. I checked the vio/org wire to see if it was connected directly to ground, and it is not. More investigation found that the right and upper jet would stick on but removing the brn wires stopped this. The divertor that allows the ball to enter the borg ship also appears to be stuck open and when you run a solenoid test, triggering this diverter instead flashes a bulb on the back board.

I isolated the CPU board from the GI board to make sure it wasnt roms going bad, or something of that nature and I had the same results. I also noticed during one test run the DMD display went distorted entirely. Maybe the aux driver board is messed up? Anyone have some ideas on where I should go next?

Thanks!

I went through that entire list several times before asking here. I wish it were that simple. There is something else going on, and I cant seem to find the issue. Have a repair guy coming to see if he can determine the root cause. All transistors check out fine. I think there is something going on with the Aux board that is causing this issue.

Not all problems can be solved through pinrepair, though it has definitely helped me solve most of the issues I have had over the years.
