[SOLVED] TP1 TM2 5 volt adjustment
Posted: Mar 22nd, '17, 03:02
Hello all,
So good news, I've gotten to the TP1 TM2 5 volt adjustment after hunting down a short in the 5V to ground.
Bad news, it's only reading 0.15V. No matter how I turn the 100k trimmer it doesn't move beyond 0.15V. I've checked all of my chips, they're mounted correctly and near as I can tell everything is sold nicely. I don't have a schematic, so I can't trace anything for continuity.
Suggestions would be greatly appreciated.
Thanks!
