said by martinh:The AC adapter is 12v 1a output but the input is 100-120v. There's another adapter on ebay with 100-200vac
Input doesn't matter, since that is usually dynamic. Its the output that needs to be correct. The other adapter was probably for those sold in the Europe market. If the power light isn't coming on after lamp test, then its probably bricked firmware. And the factory reset only changes the config file, not the firmware.
