I had my roku connected to our 65' hisense t.v. there were lines throughout the entire screen everytime we used it after hooking up our roku. A few days later our screen went out and it fried our board. We hooked it up to our smaller tv and the same thing is happening all over again. Our TVs had no issues ever prior to connecting the Roku. Has anyone had this happen? I cannot afford abother t.v. the only common denominator is the Roku. Any suggestions?
