Hey I just bought an Atari tempest and I'm getting a weird monitor problem.
I switched out Another working PCB and I got the same problem so I'm pretty sure it's not the PCB. The same problem happens no matter which PCB I use.
When I boot up the picture is crystal clear.
Shortly afterwords the picture becomes unstable and gets smaller and smaller until it dissapers and shuts off completely. The spot Killer willl then turn on.
I wait awhile and it turns on again.
Any thoughts on what's going on?
Thanks
