I dont think this is the monitor.. I repaired the 4016 and TL082 in the X output section of the board.. The screen looks completely out of whack, both on the monitor and on the scope in xy mode. The images appear in a smaller scale..but fill the screen. I was thinking that there may be some bits missing on the DAC..but both DACs? Anyway, I put the game in test mode, and Im getting two small crosshatch grids.. Looking at the x and y outputs on the scope, theres a wierd shift from pos to neg at the sametime on x and y.. Anyone ever seen this before?
