Salvaging a probably fried MiSTer? (only the BlisSTer is dead!)
Posted: Fri Oct 29, 2021 8:42 pm
Well, I maybe destroyed some or all of my MiSTer through mis-aligning my new MT-32 pi Hat and I was hoping I could get some advice on how to test what might be able to be saved.
I dropped a stand-off while seating the Pi/Hat in a printed case and decided to proceed, unfortunately! This omission allowed me to seat the Pi off by one set of pins (pins 1 and 2 on the Hat connected to pins 3/4 on the pi. Maybe notable is 5v power on pin 4 on the Hat going to ground pin 6 on the pi, etc). To add to my incredible act of self-inflicted destruction, the last two pins (I think 3v3 and 5v Power pins) were bridged by a washer and one of the screws going through the hat.
Plugging the monstrosity into my MiSTer's User port caused a sad reaction, mostly lighting based. The I/O board will no longer give me a pretty stoplight. I unplugged it semi-quickly but my hand smells like magic smoke.
Is my I/O board mostly dead, dead, or very dead?
I am missing HDMI out and SSH access to the DE-10 so I need to investigate further and am curious if anybody knows that I've also broken this?
Edit: The DE-10 at least booted into the MiSTer menu when disassembled so my day isn't completely ruined! Also the I/O board isn't the issue, apparently. When the BlisSTer Rev2 board is not connected everything seems to work okay. Just the USB board it seems. Could have totally been way way way way worse
