Screen turning on itself

[#1]

I noticed that the screen of my Sola turns on itself for a little while now and then. The intervals are rather irregular, sometimes it keeps going on and off say every minute, sometimes it does nothing for quite a long time. I stopped or removed all extra apps so I suppose it shouldn't be caused by any new app. Any idea what the cause might be? Thanks for any help.
