Re: WG 6100 Right Half Deflection Collapse

Thanks! I already eliminated the game PCB as the issue by trying the monitor on both my Tempest and Space Duel. The right half is missing with both of them. I'll keep probing around. I looked for open transistors too, but maybe I missed one.

  I would switch the X and Y inputs between the game PCB and the monitor to see if the collapse changes to the other axis... if so, then the issue is on the game PCB (unlikely). If the collapse is on the same axis, the issue is on the monitor.

  A transistor may be open (and most likely is if you aren't blowing fuses) so it won't show a short if that was what you were looking for with the meter. Pull the deflection PCB, make sure all the molex connectors have goos solder joints, I would suck and re-solder all of them anyway as they all have problems eventually. See if you still have an issue... if so, report back. :-)

    Folks I'm making progress on bringing a dead WG 6100 back to life, but am stuck. The right half of the screen is collapsed into a vertical line. The left half is fine. I checked all of the chassis mount and deflection board transistors with a multimeter and they seem fine. Any pointers would be appreciated.
