Mac Mini light comes on, but no chime.
I purchased a 1.66 Core Duo mini early last year, ran sata out the side, and upgraded to a T7200 processor. Over the past month, I got a couple of lockups under load (importing CDs), and once a GSOD.
Last week, I woke up to find my mini completely dead. The power light was still on, the hard drive was still spinning, but nothing going on. I powered it off, and back on, and it still sat silent. The light came on, but no chime, and no booting.
What I've tried so far:
- resetting the PRAM => fan runs @ max until I turn it off, front light does not come on.
- resetting the SMC => back to the normal state where the front light comes on, but nothing else.
- replacing the original 1.66 Core Duo CPU to see if I'd smoked the T7200.
- pulling one of the 1G chips out, and then the other.
At this point, is there much chance that it could be anything but a failed logic board? (The thing was quite dusty around the intake vents ...). I suppose it could be the power supply, but it seems sort of unlikely.
Nobody seems to sell logic boards, so I guess it's time to pick up the cheapest old mini I can find ($350 is what I've seen), or fork over ~$750 for a brand new one.

One thing I didn't mention above was that if I left the fan cable unplugged, the fan would spin up ~5 seconds after powering it on. If the cable were plugged in, it would spin up, but at a very low RPM (hard to hear outside of a quiet environment).

I had an SSD 120GB in it but it was working fine. mac mini mid 2007 is the same I get it to run the recovery disc then it goes to reboots and stops then will not turn off without pressing on-off button, when I turn on and light on, no chime fan spins up no boot no signal to display, I know one thing I have two power adaptors both are working. I have tried no ram one ram in top slot no luck I have tried resetting PRAM , and SMC, still no good I have put away for the time being. I even changed the PRAM Battery I got it to boot up once but it hanged on shutting down. I do own another Mac mini late 2012 so I am not without a desktop mac. I will go back to it later on when I have the time to check out all the bits
I have checked the main board and there is no damage to it, I might strip down and take the mainboard out and check the other side of it
