Summary: We purchased this TV late December and it was great, just what we was looking for. We don't have cable or sat, so we only use it connected to my Roku. The system has been maintained perfectly. 5 months later and it started "acting" up. The menu system started flipping out like there was a ghost in the machine, the resets wouldn't work, next the volumn set itself to Max and we couldn't reset the machine at all. We updated the 1 firmware update and nothing.
