ive been testing master systems out, trying to find some that work, and it seems i have 5 - all 5 i have - that have the same problem. when i plug them in i get a not-entirely black screen, but no real game image. it seems the same screen on all systems...black with some variation at the top. same on channel 3 or 4, game in or no game in.
any ideas what might be wrong?
i hooked up an NES to the same cords and it worked fine, so its not the cords...
