This might be a good one for the sticky thread if I ever get it figured out:
So I bought this Devestators game last week that had a dead K7000 monitor.
I bought a cap kit, filter cap, and a flyback. Replaced all of those parts, reflowed headers, and fired it up. Game came on for about five minutes and then went into HV shut down.
Bought a regulator and fuse clips. Put the regulator/fuse clips in yesterday and the B+ ,at that white resistor mounted to the outside of the big metal piece, was testing 160dc on one side and 120dc on the other. The screen was blurry and colors off *pic 3* so I turned the flyback up until it got better. The flyback focus turned all the way up still had a blurry screen, but it was a little better. Thinking maybe the degaussing coil was stuck open causing
the major color issues, I turned the game off, unplugged the degaussing coil, and fired the game back up.
The monitor did nothing at all and now the B+ is at 175dc/172dc which puts it into HV shut down mode.
I noticed the badly burned tube *pic 1* and sought out another k7000 tube which I found. Plugged the monitor in when I got home and it looked great *pic 2*. The new chassis had old caps/white knob flyback so I put the freshly rebuilt chassis on the new tube.
