I need some help to understand why I'm loosing 12v after some time on power supply board. Nothing attached to it. About 2-3min after power on, 12v goes out. If cools down a bit (2-3min again), got the 12v back. Fuses are all ok(4A as per manual), slow blow. Not the resettable type.
any ideas
some weird stuff now, but I'll check more tomorrow. Like putting all back and now I got 12v but the fkin led went out lol.
The board has a few LM317T. It's in a weird position and I don't have enough room in there. I bet one will test different then the other. Checked all the diodes and resistors ok. There is also a bridge rectifier that gets hot but I guess that is normal? I can check the pins and looks ok. I'll google tomorrow how to check a LM317T
And I didn't link a game because is not pin related, but lots of people here have good electronics knowledge.
Quoted from RCA1:Fine, but what is it? Different things are wired differently.
It's an Ami/Rowe WP100A jukebox.
