My Samsung ln46a650 won’t turn off or inputs from remote or from tv itself. The light on the tv shows me its reading the remote so why wont it shut off the tv or even on the tv itself…
Rob, check the power board. It should look similar than the one in the image. Check for anything odd looking. Post some images of your board with your question. Use this guide to help you with that. Just make sure that yuor set is disconnected and that you don’t poke around the components with your fingers, Capacitors will hold a charge, even when the set is unplugged, and may giving you a shocking experience.
Assumming its not a universal remote that has forgot the code or week Battary check the standby voltage on main logic and look at the plugs on that board there marked what voltage they should have if there all correct then its your main logic ( I’m betting that’s what it is )
My Samsung tv says to Press and Hold the power button to turn on or off so just trying to clear this up !
