Hi, Received a Neo X7 and it is not powering up. Not sure when was the last time it worked. I really want to get it working... (of course I read all the "not powering up" thread here...) When I plug the power cord and press the power button I can see a red light flashing for a split of a second on the optical audio port. Then it goes off. And no video out at all. Checked power supply (5v, 2500mA), and it appeared OK. Bought another power supply, just in case. Same results. (5v, 3000mA). Performed the reset sequence a number of times (paper clip + power button, etc). Same results. Installed the USB driver and connected to a PC. Windows Device Manager is showing it as "Unknown USB Device (Device Descriptor Request Failed). Uninstalling the unrecognised device and re-discovering it yields the same results. No luck with a different USB port and different computer. Obviously the RK Tool does not see the X7. Does it mean my X7 is dead? Is there any way to resurrect it? Will appreciate any advice as it seems like a fantastic thing to have. Thanks!
