What rom is running from ? The original ? Or did you flash it with one of the custom roms?

first it was on the stock rom and the screen (bottom half) was grey then i left the tablet for two days and then i put viecomb on it and it the screen went fine but then at the end of the day the screen went grey again so then i put it back on stock firmware and just now i put view comb on it and the screen is still messed up i can show you a pic
