My little sister's Polaroid tablet has gone blank.

Actually when there's a problem, most likely it'll turn white or blank (not black).

Here's what has been reported by other people with such a problem:

"If your tablet`s screen turns white, you have to shut it down. But sometimes if this happens, you can`t just click on the power button because it is also unresponsive.

You have to make a long press on the power button until it shuts down. It may take about 10 to 30 seconds to do so.

- Wait until the screen becomes black
- Now turn on your phone and see if it will be back to the normal screen.

- If the above step don`t work then you can just remove the battery of your phone.
- Open the battery cover of your phone
- Remove the battery for 10 seconds
- Put the battery back
- Open your phone and see if the screen will go back to normal.

If the method mentioned above don`t work then the problem is on your phone's LCD display. Maybe it`s damaged and it needs a replacement.

The best thing to do is to bring it on the nearest repair center and ask for a free checkup (most repair center offers a free checkup).

After that they will tell you the problem of your phone. It`s up to you if you want to put it on repair or not.

Usually the labor is cheap but the price of your phones part is not cheap."
