Apologies if this is posted in the wrong section.
I'm a complete newbie to dna mods. I bought a 2nd hand Hcigar vt133 the other day, it worked fine for a couple of days then yesterday it all of a sudden died on me, the screen is completely blank, unless I plug it into Escribe then I get "warranty service" flash up on the screen. Also the device monitor isn't showing any cells either. Any help fixing this would be much appreciated. Thanks
