I purchased a Rino 120 over ebay. When it arrived I turned it on and seemed to work fine. When I tried to turn it on again the unit vibrated, but the screen went dark with thin vertical lines in it. I saw something similiar in fixya.com and tried to reboot it. It turned on and worked fine for 2-3 more times. The next time I tried to power up, it vibrated, but the screen went dark again. No luck getting it back up and running. Anyone else had a similiar problem?
