Garbage on screen and loud noise from speaker sometimes
Finally got my Atari Avlanche working but sometimes when I turn the game on there is a loud noise coming from the speaker and there is garbage on the screen, but if I turn it off and back on the game works fine or if I connect and disconnect the board from the edge connector the game works okay. When I do the self test for the game is shows that the RAM and ROM are okay, when I got the board the voltage was low so I replaced the voltage regulator and for some reason that regulator caused the voltage to be 7v+. Put on another voltage regulator and now the voltage is fine. Could have that high voltage damaged something on the board, I didn't smell anything burning at the time. Does that sound like a board problem or a bad connection somewhere?
