No picture or sound - Time Warner TV

#1
This question is about "No picture or sound", with Time Warner Cable TV and apps. I have the STB connected to a stereo receiver. I also have a blu ray player and a fire TV stick. Everything is 4k capable except for the Spectrum box. I was watching cable TV and switched over to the firestick. Once done with the firestick, I attempted to switch back to cable TV. The receiver is giving me a message that says "stb refsw desi". I've attempted to research this and what I'm finding is that it's got something to do with the resolution settings.



I can't get any display on the TV to see what the stb settings are. The TV automatically controls the resolution so there's nothing to change as far as TV settings. Plus, I already called support for the TV and confirmed it wasn't a TV issue. Trying to figure out how to fix this issue.
