OK! There is no beeping noise when you try to turn it on. I will try to see if the ram in properly installed and I do get some kind of lights coming from the mouse when plugged up and the key board do flash it's lights when plugged up.

@Norris - the power supply is really a part of the adapter, so most likely it is a logic board issue. If there are any beeps when you try to turn it on, you may want to check on the RAM. The machine won't turn on if the RAM has gone bad or not seated properly.

When I plug in the power cord into the mac mini, you can hear the fan running but no power or no light that comes on when you push the power button. Do you think that the main power supply on the mac mini is blown out? Can a power failure or storm that can blow the system power supply inside the main mac mini?

The video repair guide for the Mac mini was accurate and easy to follow. I was able to replace a logic board, add more ram and upgrade the harddrive in one operation. Thanks for the guide, I will definitely seek out PowerbookMedic for future parts and repair guidance

Thank you. I think the brick is shut, cause I'm reading up to 39.xxx which I will assume is bad...
Thank you guys.

input AC 110-120V 50-60Hz 2.0 A
output 18.5V 6.0 A
From brick to mac mini (cable) should read at least 18.5 v right? not more, right?

@Alex - it should say on the brick what the output voltage and current should be.

The power brick could be a culprit too for not booting up. But I've tested it and I get 119 on the cord from the wall outlet to the brick, but when I test the brick cable to the mini, i get different readings..what should it be?
Thanks

thanks..I've just got one that is not booting, not powering on either. Nothing. and I discover that when I open it, that particular assembly is off and the 'connecter' came off the board...It cannot be put back because it looks like its off the soldering part. I know, how? beats me...will re-assemble again and give it another try.

@Alex - it should work fine without it.

Can a Mac Mini 2009 run without the 'sleeper light" assembly?

@rafh - that sounds like a kernel panic based on your description. That can be caused by several things including bad memory, a defective hard drive, or a bad logic board. it is usually best to get it professionally diagnosed so a lot of possible parts can be tried out.
