Quoted from collieguy653221:
Hi, I'm new to Pinside. Decided it was time to get my games out again and get them working. I have a Bally Star Trek. The game has been in storeage for 20 plus years. Plugging it in, I get lights, activating a new game I get two clicks, flippers work once or twice and that's it. I'm a em guy and do not know that much about solid state games. I have no idea on what to check first and how much things cost to fix. My game was well played when I got it showing wear down to the wood in the center of the playfield.
Any suggestions on what I need to do next to get the game going would be appreciated. Thanks, Steve
Welcome to Pinside! You've got a great classic game, and pretty desirable. Here's where I'd start:
#1 - figure out how far the MPU gets into booting. Follow the instructions on this page, Section 188.8.131.52:
#2 - Depending on what you find above, there are a number of ways it can go. My general recommendation would be to confirm power is good to all PCBs. Disconnect all cables except for the power supply rectifier board and confirm the test points on the rectifier PCB match what's expected when the machine is turned on:
#3 - If the rectifier test points are all good, plug in the Solenoid Driver Board (SDB) and check those test points. Then do the MPU. Looks like the MPU has the original battery (convert that to NVRAM or remote battery pack as soon as you can) but at least from the picture you provided it doesn't look like there's any acid damage there.
My guess is that you're going to find some test points on either the rectifier board or SDB that are incorrect. If/when that happens, next step will be re-pinning the connectors for that board...they get corroded, bent, or loose after 40 years. If that doesn't bring it back, then it's time to figure out what board to actually repair (plenty of folks here on Pinside will do board level repair if you don't do that kind of stuff yourself).
