Especially if the board lights up. Our V1 units, the customer had to load the firmware , IE it wasnt pre loaded like it is the V2. This means a blank screen is normal. Show me the cables you’ve tried. I can only diagnose for certain a Mega 16U2 if you can connect it to a PC. The dreaded “USB device malfunctioned” error will appear when this is the case. For the moment, im still thinking cable.
