My UBook Pro has a black screen and will not turn on. I tried all start using the advice on here and it still will not work. I contacted Chuwi and was told to “If it does not flash, please replace a charger and charging cable to charge for 0.5-1 hour,then short press the power button three times, then long press the power button for 10 seconds to start.” That did not work and I sent Chuwi a second message. Their reply was: “If the tablet does not turn on. You need to send it to the repair point to check the hardware. We have repair points in Russia, Spain, Hungary, and Hong Kong.” I can not believe they do not have a repair facility here in the USA.
Does anyone have any suggestions that might help me in getting the screen turned on?
