Mac mini a1176 with a power LED but no picture
Hi all. I’ve been troubleshooting a Mac mini A1176 for a little while now. When I power on the computer, the white LED shines without blinking and I can hear the CPU fan and optical drive start up. However, no video is coming from the Mac. Additionally, I can’t tell if there’s a startup chime because the built-in speaker appeared to be damaged. Here’s what I’ve done so far:
- Reset SMC
- Checked wire connections inside the Mac
- Cleaned out the internals
- Replaced CPU thermal compound and replaced CPU with a Core 2 Duo T7400
- Replaced PRAM battery
Would it be the integrated graphics, a faulty DVI connector, or something else causing the issue? Also, is this salvageable or should I break up the machine for parts? Thank you.
