Newbee needs Ideas.
PROBLEM: I get a loud humm from the speaker and lines across the top of the screen.
1.I have replaced all caps on gameboard,power supply and monitor
2.reseated all chips I/C's
3.looked for any burn't bad spots on board.
4. Checked resistors for opens.
After I reseat the I/C's and fire the game up everything works good then after about 30+ seconds sparkles appear on the top of the screen and crackles in the sound then the humm sound happens and the lines appear and stay.This has happened twice
ANY IDEAS??? I'm stumped---probably 15 cent part kicking me in seat--See pics below--All help will be appreciated--Thanks------Kev
