Just picked up a Star Ship Troopers. Most everything is working fine but I don't have any GI. I have checked the voltage coming in to the board at J14 and it's 7vac. If I have checked correctly at J15 (going out to GI) I get 5vac. Not sure what to check next?

Also F7 was blown but when I replaced it the green flashers came on and stayed on. Pretty sure that's not right so I pulled the fuse. I have no idea what could be causing that. something shorted I assume.

I'd really appreciate any help or ideas on where to start looking to solve these issues.

thanks guys,

Yeah, I'm getting continuity to the sockets I have checked but no voltage. I guess it's getting grounded. You're right I have to work my way thru. Damn! LOL. I always get confused with AC.

Okay, I found that it's a TIP122 Q27. I'll pull the board tomorrow and check that. I think I have replacements. I can check them but I always have to have instructions in front of me

I'm an idiot, I just remembered when I got this home and played a couple games I noticed the left sling wasn't working and discovered that there was a ball stuffed under the sling plastic and tightly wedged against the sling switch and a broken GI bulb. I guess I'll have to check what happens when those are shorted together to find my problem. The switches do work. seems odd that all GI is out.

Nope. I pulled and checked all of the GI fuses and all were good.

Thanks Guys! A bad TIP122 at Q27 was causing both issues. All fixed.

I'll probably find some other issues while shopping it out, but this was the main one.

On a side note: the game is fan friggin' tastic. I'm glad that I finally picked one up.

Thanks for the tips
