I can't make the TV stay turned off. I am using the top right hand button on the remote (the red Power button). When i hold it down, it says "system shutting down", then it turns off. Then, in about 2 minutes, EVERY SINGLE TIME, it turns itself back on. It started this about 2 weeks after i received it and originally it was sporadic and now it is happening 100% of the time. My system is updated. I've tried double clicking, holding for the button for 10 seconds, etc... nothing is working!
