Got the fhd 2k stick delivered from Walmart last night. Everything was fine until later last night i jumped up out of my sleep because the damn thing made a screeching static sound on my tv and shut off. Since then it is fine for a few hours then it makes the loud static sound with a black, green or white popcorn fuzz screen. It then either turns off, continuously reboots or i have to unplug it and turn it back on.... Anyone else have/had this problem or know why it's happening? Is it faulty? Should i return it?
