It was also suffering from the infamous freezing problem - completely froze when installing Firefox. Tried to reboot, then it froze on bootup. tried again then it froze on Viliv logo. Tried again and now it isn't showing anything on screen any more...
Shame that the Viliv were so problem ridden. I tried removing battery, I tried letting it rest for a week - nothing. The power led lights up and the other also for a brief moment, but then nothing, just the power LED stays on. So I am pretty sure it's not a display issue - otherwise you'd see HDD activity.
