Weird screen problem with my infuse.

[Goneeuro]

so I noticed that my phones screen will come on for no reason. Its like i hit the power button to check the time or something. It just flicks on to the lock screen then after a few seconds it goes back to sleep. I dont know if it has anything to do with Serindipity 7 or not. I flashed that onto the phone a couple of weeks ago. I dont know if it has been doing it that long. I just noticed it the other day and i cannot figure out what is causing it. I was going to wipe the phone and reinstall serindipity. I love the rom and dont want to go back to stock. Does anyone have any suggestions before i wipe the phone and start fresh???
