I heated a Nvidia 780 graphics card a few times using a heat gun and a laser thermometer (max 200 degree c). I did not want to use my oven as I don't want to risk it. That revived the gpu 2 times, going from vga quality and weird screen artifacts, to no issues at all, 2-3 months with each bake. In the end i bought a new one as it really is temporary.
- shereadsthenews 7y agoI repaired a 2009 iMac gpu the same way with a heat gun but that was good for two years each time the first two times and didn’t work the third time. It’s worth a shot if you strongly suspect broken solder ball.
- ovi256 7y agoSame here, for the same equipement. Did not use heatgun but oven, wrapped in tinfoil. Same results as you reported. Finally sourced a compatible GPU from eBay, an ATI 5xxx from the next model year iMac. It was much much cheaper than sourcing an ATI 4xxx. Opening the iMac the first time was very stressful.
