She gave it to me, I took it apart. One of the headers that connects the power switch to the mainboard was just unplugged. It took literally 10 minutes to “fix” including disassembly and assembly, and all I needed was a screwdriver.

My buddy has a $6000 projector. He found it in the trash. The only thing wrong with it was a cracked solder on the power supply.

Similarly, I have a $5000 audio console that I got for ~$100 in parts; it had a bad power supply. Honestly, probably just a bad capacitor on the power supply, but I didn’t feel like desoldering every capacitor to check their capacitance. Swapped out the supply, and it has been working fine ever since.
