Corrupt graphics display - Hardware Solution Needed
2011 Dual-core Mac Mini 2.5GHz i5
(Bought a "for parts" Mac Mini to work on)
After installing a borrowed Mac Mini drive... and installing the missing parts (fan, cables, etc) --- when I boot the machine up, there is a lot of graphic distortion. All kinds, in fact. I ran the simple AHT... even though the screen was totally screwing up, it said "no trouble." Running extended now. Will update.
To confirm, this is NOT an issue with the connectors, the cables, or the actual display I'm using. All KG items. Memory is also KG from another MM 2011.
What I did do: replace all the thermal paste sites (under large heatsink, and on reverse side for the separate 2 chips that I believe control the Firewire, etc but are NOT the graphics chip.
