have a 3115 with a burn hole under what was f9700. Restored 3v42 to fuse. Burn hole however is puffing smoke when I plug it in and no fan. I've had bad luck with burn holes. Any suggestions? Or junk?
You can try scraping away at the hole in the hope the short disappears, however its usually a fruitless exercise. I just trash the board when this occurs.
