I think I need a guru on this one. I sold a buddy of mine a Centipede stand up, and everything worked perfect. We loaded it up and off he went. He got home unloaded and let it sit until the next day. Check all wires and connections before powering up. He said He did all that and all He can get is a green screen. Any ideas.

Did he reseat the neck board? Have to be careful to not touch any traces on the neck board or can get a shock. Most initially had a cardboard cover over the solder side of the board. I would try a reseat initially and verify connections on the chassis are good. May want to discharge the tube or just be careful and be sure the machine is powered off while doing this. :)

Maybe the green output transistor is bad? I had a tube that was really red and it was the red transistor.
