I'm very sorry to hear that has happened, and I apologize for any inconvenience this may have caused you. In order for me to help you most accurately, please provide the complete model code for the TV?
Our remote all of a sudden stopped working. We changed batteries, my hubby fiddled with the inside - no go. We bought a brand new remote and still not working, does this eman something wrong with remote sensor on tv unit or is there a lock taht maybe on??
