So I purchased a QFR (unbranded, blues) that the seller said was broken. It is only about 4 months old. I opened it up to find that the Mini-usb port was plugged in only 3/4 of the way to the PCB. Quickly fixed this and then plugged in the keyboard. Still did not work, BUT the microcontroller is heating up. Not recognized on the computer yet. What is happening, and how can I fix it?

uM.. check for broken traces, cracks in the pcb, check the pins on the controller board, make sure the pins are all soldered down and non are shorting.
um... check the usb breakout daughter board for shorts.

Yeah, this seems to be the problem. Too bad CM Storm won't grant me an RMA because the warranty seal is broken :(

I have the same problem :(

I wonder if they void the warranty when you buy a replacement top panel and install it.

If so, that's quite nasty.

Stupid question - Isn't CM who sells replacement covers?
If so, do you have to break the warranty seal to replace the cover?
They seem to make 'exceptions' for those....

Do you see where I'm heading with this? CM is currently selling them for 10$ :-)

yea, but how would he know it's YOU... less he's haxing and getting you ip located.. within 20meters

First of all check that the internal USB cable is seated properly on the PCB, and that it's not plugged in upside down or something. I'm pretty sure that's not the issue, but it pays to check.
Secondly, I would imagine if the cable were only partially seated, the higher resistance and other factors could easily contribute to a controller dying.
Lastly, just wait for someone to make a replacement controller and install that, it'll be better and fixed!
anyway, if you don't want to bother with it, I'll buy it from you. I enjoy fixing broken keyboards.

I'm looking for $68 shipped for MX greens (see http://geekhack.org/index.php?topic=35155.msg651905#msg651905 ).
I'm also looking for a replacement controller so I can fix it without having to sell it :P

OP don't assume anything is fried, here is why:
- broken solder joint on the mini USB
- people reporting the same problem as you, tested it with different USB cable than the CM and problem was fixed
- not really likely, but remove the controller and check for broken solder joints on the pins where the controller attaches to the PCB, the controller is located above the arrow clusters.
