Sorry for the long read.
I have a wg 7500 27" in a Gaunlet Dark Legacy that wouldn't stay focused so I replaced the flyback, did a cap kit and reflowed any bad looking solders I could find. I cranked it up and adjusted the colors as per Randy Fromm's directions in The Big Blue Book. Looked great! Then it went out after about 10 minutes. I still had neck glow so I played with the connections and the chassis grounded out at the top left where there are no supports and the board bows down. The 5 amp fuse blew in the cabinet power supply.
At this point I took the chassis back out an looked it over again. The fuse was good. The 3 transistors on the neck board were kind of floppy, lifting the traces, so I jumped the traces and ran a small bead of silicone across all 3 to tie them together. I also noticed a component in the rear of the first picture that looks like a horz. width coil with out the adjustment. It was loose from its base. I also siliconed it. I put a piece of rubber under the sagging board corner and reinstalled it. The second picture is what I get now. No color. I tried adjusting the colors as before but no good. If I try to turn up a color the whole picture washes out with that color but the color never gets vivid. It always looks washed out. Same thing with my pattern generator connected. B+ is 130. video B+ is 198. Is it that coil thing? Or my silicone across the transistors?
