2011 Mac mini GPU failed (Radeon 6630M) - repair options?
Recently my mac mini failed critically while streaming videos. The screen started garbling, then went a weird pink colour. Now it wont fully boot, after showing the apple logo with the boot progress bar for a few seconds it flashes to a white screen with some faint vertical banding.
I managed to disabled the discrete GPU (Radeon 6630M) and now it boots to desktop but the graphics are pretty awful using the integrated GPU.
My options seem to be:
1. Try to 'reflow' the chip. However, it seems this would only be a temporary fix. Or can anyone recommend a high quality repair service that could fix it in a more permanent way? (reball the chip?)
2. Replace logic board. Second hand logic board $150 to $200 on ebay. Some risk that it would fail again.
3. Buy a new system (most expensive, $800ish for comparable specs).
Anyone else faced this? Any other options to consider?
If you reflow/reballed, how long did it last?
