My beloved Tempest machine developed a couple of problems lately. First, I powered it on and the screen was completely reversed left to right, like a mirror image. Then a few days later, I powered it on and the bottom half was gone.
I traced the latter problem to a bad power transistor (Q706). I replaced it and the bottom half returned. However the reversed video persists. It otherwise plays ok. The image is bright and stable. All self tests pass.
Does anyone know the fix? Is this a common failure mode with a (hopefully) easy fix?
