I'm sorry to hear this. Have you tried power cycling the television? If it continues, I would recommend reaching out to us directly at qasupport@sea.samsung.com

I have a Samsung H7150 65in TV, the other day I saw the IR light flashing and all remotes stopped controlling the tv as if it were receiving signal from somewhere else. I removed batteries from all remotes in my house, light still flashing. Attempting to use on TV controls they are unresponsive as well. Removed all HDMI and USB connections problem persists. Has anyone experienced this and how were you able to resolve? This TV is barley over a year old purchased brand new out the store at the end of 2014.
