Hello all!
Bit of an odd one here. I had found a iMac G3 DV/400 Granite model at an e waste shop for cheap a while back. It was sold to me as "non working, display only." Of course, I buy it thinking "Its probably just a power supply or something."
Nope.
A school district had done the "drill a f-ton of holes in the motherboard" style of decommissioning of it. The logic board is more or less toast but I was able to source a replacement (albeit its a 350mhz board, but I have ideas for the future.)
The one item that has me stuck is the PAV board. The drill managed to take out a section of the PCB around IC904. Somehow only the PCB and trace were damaged. That said, I have been trying to source pictures of the solder mask side of the model 661-2370 (LG) PAV board. Based on the location and the function of that area seeming to be related to 12/5v regulation, I think it would be feasible to run jumper wires to repair the damage. I've been trying to source clear pictures of the traces in that section of the board online but haven't had much luck.
TLDR: Does anyone have pics of the bottom of the LG PAV near IC904? I would really love to revive this lovely machine.
Much appreciated for any guidance you kind folks would have.
PS: Here is an imgur album with the logic board damage
Edit: I was able to repair this with some help of a photo from a member of the MacRumors forum.

Rebuilding iMac G3 PAV traces (model 661-2370)
Hey all, I'm currently working on bringing a brutally decommissioned iMac G3 DV/SE back from the dead. Short version is someone drilled through the logic board in multiple places and one hole extended through the PAV board near IC904 (Looks like a 12v LDO.) The logic board is a lost cause and I...
