PG Xeon 1200.1

[ampman37]

I have a PG xeon 1200.1 I hooked the power wires up backwards, first time ever. Anyway I took it out brought it in put it on my bench and tested it and to my surprise it came on and worked fine. Well after a couple hours of use I left my friends house amp came on and played for probably 30 seconds and quit. So I stopped got out to look if the blue light was on and it was flashing. Now poer is going to it but no blue light and no flashing light. I never even pushed it cause I'm only running a 250 watt eclipse sub that sounds amazing in the box I built it for. I repair amps for a liveing and install car audio/video. I am wondering if there is a code to the flashing light? I did'nt have time enough to see if there was a certain number of flashes. When I lifted up the seat to check on it thats when I seen the light flashing. I'm thinking the power supply fets may have gone out, some not all. I'm just trying to find out about the flashes and now no lights. I'm gonna pull it out bring it in and see if it needs to be like resetted in a way. By unhooking power waiting a while then reapply power and see if it works or if I get any flashes. Any thoughts or help would be appriciated. I know I can repair it It's what I do I'm thinking all the guys on here with tons of experience with PG amps would point me in the right direction before I start my normal repair process and find out about the flashes which I know is gotta be a protect mode. Trying to figure out if there are different number of flashes.

The usual issue on Xenon amps is cold solder... the first-batch manufacturing quality wasn't great. After awhile, PG started reflowing all of their boards, and there were way less issues. Unfortunately with cold solder issues, it's a complete pain in the ass to figure out where the actual broken connection is.

Other than that, check out your usual culprits (stray wire across terminals, etc).
