Shut it down by holding the power button until the screen goes black, don't tap the power off button, wait for the black screen. Then let your phone charge for a few hours (maybe over night) with power off and see if that helps.
Sorry about this.
Well, seeing it is a new tablet, either of two things can be done.
Your tab is booting beyond Startup but you ain't seeing it because of the contrast/black screen setting.
To confirm; step into a dark room/space and hold a flashlight very close to the screen, you'd see your tab is at its home screen already.
Anyway, you will have to default factory reset it as it is or you could attempt to navigate (while in the dark room/space and using/holding the flashlight) Swipe to open/unlock it----Settings----display and brighteness-----brightness----'move cursor up to increase brightness'. Done.
Second option with dark room/space is tedious and strenuous.
Factory/hard reset is an easy option to try.
At the same time, hold/press both the volume up key/button and the power button/key.
Follow the system prompt afterwards.
Or
Press/hold down the volume down button/key and the power button.
Follow the system prompt thereafter to factory/hard reset your tab.
I cant help you resolve your problem but i have the same problem with my Toshiba but when the screen goes black i get a high pitched buzzing and i cant do anything but turn it off. I was replying because if you got a solution to why yours was doing this would be great if you could help me out..Thanks Tanya x
did you checked the settings on your cell because there are some adjustments to the lighting of the screen surely you didn't put lighting and that's why it wont turn on
Without knowing your model of phone it probably needs the firmware updating or, more likely, the backlight on the LCD screen is knackered. To test, turn on your phone in a dark room and shine a torch onto the screen. If you can see some of the screen then the bscklight has gone. Also try connecting the phone to your PC & updating the firmware.
my zen was dark and i cant see whats in it.. i can only hear songs but the screen was dark.. when i turn it on again same situation dark screen.. pls do help..thanks and more power..
This is a very easy fix. Your cable box is not grounded correctly. To fix this you need a AC Plug adapter. This will change your TV ac plug from a 3 wire to a 2 wire. This may sound funny, but trust me on this. I have fix a lot of TV in NY doing just this.
