360 Won't Get To Nxe Menu With Dvd Power Plugged In, Cable damaged? Drive damaged? Options

[STKD]

Fairly simple problem. My 360 will not show the NXE menu if I plug the dvd power cable into the drive. Oddly the cable appears to be supplying power just fine (as I can eject/close the drive using the front switch), but if I turn the 360 on with it plugged in, I just get the center light on theLED and nothing ever appears onscreen. If I turn the 360 on and then plug the drive power in, it instantly loses video and the NXE disappears, then again the same light comes on.

I've also tried plugging the drive into a PC sata connection (previously used for backing up the drive firmware/keys) with the same power, and it doesn't seem to show in the BIOS now. This all happened while trying to unlock the drive with JungleFlasher (I basically clicked unlock a few times and one time it just stopped showing up..)
Anyone had this? I could really use some advice on it.

Just wanted to add a thanks for the idea of trying to replace the PCB itself. Ordered a replacement one from ebay, seems to make sense that it is either the sata or firmware chips damaged and the soldering doesn't look too tricky for replacing the PCB.

One thing I'm unclear on is once I have replaced the PCB, do I need to flash the firmware on it with the firmware/key from my original Benq so the new PCB/firmware chip will work with my 360?
