Well I attempted doing the pencil mod via TechPowerUp's instructions for the HD4850 and it did not go well at all

I've since erased and cleaned with alcohol the pencil traces in hopes of reviving my GPU but that didn't help either.

Basically I have total screen corruption. Some random characters with a few that are readable along with some funky colours. It's also extremely low resolution (or high?) that my LCD cannot display it at times. It doesn't work at all using pure DVI, but I can get the above stuff using DVI-to-VGA.

I'm assuming there's no way to fix this, but if there is a way, I'm willing to try. I'm not exactly expecting a response from Diamond anytime soon.
