I’ve tried 2 remotes, but same result. I can scroll up or down through 4 inputs, but when clicking OK/Select, it doesn’t accept the change.
Hi @bgo2ri2l , Do you have anything connected to the desired input(s)? If so, is the device switched On? Have you tried using the input button located on the back of the TV to see if that can select an input? Here’s an image to show where it is located. I couldn’t find the model number that you stated, but I found one for a Panasonic Viera TC-P50S60. Is this the model number that you have?
