My Roku Premier has been overheating that last couple of days. I've unplugged it countless time to let it cool down. Today I had it unplugged for more than 8 hours and after 10 minutes of watching TV on this Roku, the overheating message popped up again. The device is away from any electrical devices while plugged in AND has a fan on it. Is there anything else I can possibly due for this because I'm not getting any answers.
