I had that same problem on my 9700 and a I solved it by isolating the connection of the display with the motherboard in the part where it touches the plastic chassis. Don't know if it helps. The problem (in my case) had nothing to do with the display it self or any software bug, it was the connector of the display with the mboard. (I know there's a post about this somewhere in this support forum). By the way....it worked and still works just fine!

Welcome to Support Forums
There are many reasons for the problem you are having like it may be because of a weak Battery or sometime because of any bad apps and somtime sadly because of any hardware issue , But before considering it as an Hardware issue I think its wise to look for other options to narrow down the issue.So can you confirm is your Battery is in good conditions or if you had installed to many unknown applications on your device.Let us know.
Meanwhile if you had not done a battery pull restart please do it like this device POWERED ON remove the battery and also remove any media card then wait for a min. re- insert only your battery and see if that helps.
