TV Repair Questions? Ask a TV Technician for Answers ASAP
Thanks for reply so far......
I have now sorted the problem myself..... I had a PS4 controller on charge via one of the USB sockets in the back of the TV.... seemed to have blocked some functionality on the TV system menu!? As soon as I unplugged it allowed me into the sub menus, and stopped switching channels!! Odd one?? Remote(s) are all fine and working perfectly, no storms or power trips, TV is just over a year old (typically just out of warranty!!!)
