Tempest playing blind...or almost blind. But monitor is fine.
I rebuilt the monitor in my Tempest Cabaret and it looked like it was playing blind at first. But then I noticed I sometimes was getting tiny vectors near the center of the screen if I turned the brightness up. But spot killer was flickering a lot.
I moved the monitor to a known working Tempest and it looked great. So the monitor is good now.
I went through and resoldered all the header pins on the connector between the two boards and re-seated all the socketed chips and tried it in my working Tempest cab. But it still was doing the same thing.
Mostly there's just no image at all. Are there common culprits for something like this or do I just need to start at the beginning and try to troubleshoot the cpu board? I hate troubleshooting cpu boards most of all.
Thanks.
