Title: Garbled screen help-1980 Sega Gremlin space firebird Post by: JasperQuibbs on June 20, 2017, 08:50:15 am Hello everyone! I'm new to this forum. I recently got a space firebird cocktail from a friend. When I turn on the power the screen just shows random graphics and there's a sound playing on a loop. I've tested the voltages and checked the fuses and everything looks in order. Someone did modify it to coin up with a button but it does nothing. Any ideas?

You checked the basics well. Time to get a little more advanced. Usually people test a cabinet by swapping out the game for another one that is known working, although I know that can be tough.
