I'm still trying to troubleshoot my Tempest upright. When turned on, the red LED on the board lights...the speakers make a continuous heartbeat-like thumping sound, and the coin counter clicks in tune with the sound. Onscreen is the infamous spot killer, and occasionally matching the thumps, a vertical line shoots from the spot going to the top and bottom of the monitor.
Are there any likely culprits that others have encountered? I've already pulled, cleaned and reseated all ICs.
