Tablet was put on charge ,after battery low warning, next time we tried to it ,it would not work , checked the forums and decided to replace the charge socket , this was not the fault , tested the battery and this is at 3.6 v, tested the power input and have 4.8 v at connector at end of the ribbon cable from the usb socket .
tried the power and vol up reset , and the power ,vol up and vol down reset, all to no avail,
,I believe the display sceen has gone , how can i test it ??????
