I'm working on a Tempest with a board issue. I've verified the math board and interconnect cable are good. The issue with the board is there is video present in test mode, but not in game mode. The screen in test mode doesn't show any errors although the knob control read out is not a number as it should be. Instead it is a straight line and if I turn the knob the line move somewhat like a clock. See attached pic. Switching from test to game mode I can see a game picture that is mostly correct with a few random/stretched vectors. The spot killer kicks on quickly and I can only see the pic in game mode for maybe a second.
Any suggestions on what to look at?
