TECH: 6 in 1 switcher is kicking my PS into Protection mode
I have had my Jamma 6 in 1 switcher for a little over a year now. Months ago, sometimes when I would turn the game on, I would only get a/c voltage. Most of the times unplugging the game or jamma harness or waiting a few minutes would get it to work again. I eventually replaced the power supply, thinking that was the culprit. All was well for a day or so and eventually it did it one or two more times and then continued working for some time after that.
I just moved and I unplugged all the games from the switcher before I moved the game so it was safe to move. I go to reinstall everything yesterday and once I get to the third or fourth slot, the PS starts going into protection mode. Basically, the game comes on for a second, than the PS LED shuts off and stays off. I have to turn the game back off for a second or two until the led on the PS and switcher flashes. Than I can turn it back on and sometimes it comes on and sometimes it doesn't. I originally thought the issue lied with slot #3 as every time I would have a game in that slot, it would go into protection mode. Now I am not sure though as it seems to be doing it randomly even with pcbs out of slot 3.
I pulled the switcher out yesterday and reflowed solder on pretty much every connection on the solder side of the board. I reinstalled it and added a game to a slot and powered it up to test it one by one. I got all the way through every slot and it was still working. Success I thought happily. Well it turns out, this beast was just waiting for me to move the switcher into place and screw it down. Than it started giving me issues again. Does anyone know what I can do to trouble shoot this thing? I could probably figure out how to check voltage on it and everything but it seems like something is shorting out causing the PS to go into protection mode. I have no idea how to check for that. I see no obvious problems such as touching connections or anything. Please help. I would rather fix this one than have to waste money on another. I do have a logic probe and multimeter I just am not sure how to use them in this application
