Just picked up a Tetris game with an RCA monitor... everything is cool except for there is no red... I checked the output from the board and it is working... there is an interface board that outputs to the monitor... how can I tell where the problem is... whether it is something in the chassis or the tube... I have read about "guns" not firing but I don't know how to safely test the tube... any suggestions?
