Tablet works but screen is black

My tablet is working I can hear my music playing through my head phones. But the screen stays black when I press the power button I can barely see the screen light up showing that it is on. Help please. Before the screen went black it was glitching out

Answered! View the answer I have this problem too

Is this a good question?

If your screen isn't broken it may just be a loose connection, I assume that it is built the same way as the A1-830 so you should be able to pry the back off and check the connection. If this doesn't work then you will likely need a new screen to test/replace the current one.


It doesn't display. It just lights up. When i turn it on it turns on it vibrates but the acer logo doesn't show up nothing shows up except the light up. If you can find a video on how to take the back off
