I pulled the control panel off to do some work on it. There was a broken wire by the torpedo bulbs. I soldered it on, cleaned up other things and put panel on. When i started a game, i notice the score line was missing, as well as the line that says how many torpedos left. I reach into harness to undo a random ground wire i attached, and noticed harness was warm. Turned off game, removed panel and immediately saw i had soldered thd bulb ground to the 5v peg by accident. I unsoldered, and put on ground peg. Put panel back in, and it still doesnt show score or torpedos... UNTIL you shoot a ship, then score line appears. Torpedo line stays blank, until you fire a torpedo and then that line appears. After you get those lines to appear, they stay for duration of game. All other elements seem to be working fine. Any ideas?
 
I'd probably start by replacing the two 74LS153's at locations F6 and H6. Also test
the resistors at R41 and R44. Those are the closest parts to what you shorted.
