Ugh, so I went to test a laser, and grabbed the wrong AC adapter, instead of 9v center pin NEGATIVE (PS: FUCK YOU Coherent!!!) I put a 9v center pin POSITIVE
poped my coherent labmaster
had to replace some tantalum caps and got it to turn back on but it failed the self test, after some probing it seems like the 5v reg for the sensor section is borked, so ordered a new one from mouser and crossing fingers that I can bring it back to life
