Fixed a 60-in-1 for a friend tonight. The board was stuck in the Service Mode. It booted right to it and would not exit without a power cycle, then it would boot right back into it. It never booted to the normal load screen. Normally this would be caused a stuck service or test switch, but those weren't wired up so I knew it wasn't that. I took the board home for testing and after tracing out the pathways and probing around, I quickly found that the input at the PR15 resistor 'bank?' had a minuscule solder bridge between the input for Coin 2 and Service. Removed the bridge and the board is booting normally and working fine. I looked up this issue and found that people have experienced it in the past without finding out the problem. Well, here it is. Posting this info in case anyone else runs into this problem down the road. Here are some pics for reference. Game on!









 
Nice. Good to know some fixes involve the passive components and not the digital logic and/or programmable devices.

Now, how did that solder-bridge come about? Likely poor quality manufacturing for these 60-in-1.

Most likely. From my research, a few people have had this exact issue, but they had a stuck switch or a ground issue. All I had hooked up was the power and the video, so NONE of the inputs were even connected, meaning I knew it wasn't a stuck switch. That's when I started looking at the input traces and found the bridge.
 
Thanks for posing for posterity. I was working on a couple of these boards and shocked to find almost no info on the forums about repair solutions.

That's because they're almost never worth repairing. At $40 each, very few people pay to have them repaired. They just replace them.
 
Personally, I'd like to see some info on programming them.

To do what? Add your own roms? Not gonna happen. These things are running a version of MAME that's so old it's a wonder the games even run acceptably. Some really don't run well at all.

There are other boards out there that allow for programming.

Yes there are, BUT there WAY overpriced and are still prone to failures (although not as badly). The only good part is that the people that made them can sometimes repair them. These ElCheapo boards no one really cares because there easy to replace for almost no money. It would be nice to see these cracked though, like the XXX in 1 boards but a simpler easy to do way.
