I want to add I have tried it all unfortunately to no avail. Tried a different HDMI cable, taken out the hard drive completely deleting all partitions and then reformatting it, also ran chkdisc , no issues or errors found. Then formatting it again in the unit. I have reset the system, again zero. I have tried to re-install the firmware via USB as recommended by Humax, the unit refuses to engage this process. I am at my wits end, I just want to throw it away.
