Input Select jumps to Live-TV without using remote

[MAUICUDA]

Hardware: LG OLED55B7P, and Spectrum Cable box. When  I use the Spectrum remote to select "GUIDE"; so I can details about program before selecting to RECORD - whenever I push the Spectrum remote button that says "Guide", the TV at the same time changes my normal input from HDMI to "Live TV".

This is a new problem; am not sure when it started. Will I have to do the LG download again?

It might be something related to HDMI CEC option. If there is such an option in cable box setup, try to turn it off.

THE SPECTRUM REMOTE AND ITS BOX ARE PROPERLY GOING TO THE "GUIDE" FUNCTION WHEN I PRESS "GUIDE" ON THE REMOTE. THE PROBLEM IS THAT WHEN I PUSH THE "GUIDE" BUTTON, IT ALSO CAUSES THE LG  OLED TV TO CHANGE INPUT FROM HDMI TO DIRECT TV (ANTENNA TV). I DO NOT HAVE ANTENNA; AM ONLY USING CABLE BOX TO PROVIDE SIGNAL TO TV. DO NOT SEE HOW ANY CABLE BOX SETTING CAN CAUSE THE TV TO CHANGE INPUT, UNLESS TV IS MALFUNCTIONING, OR REMOTE CONTROL IS PUTTING OUT TWO CONTROLS AT THE SAME TIME; IE: TURN ON "GUIDE" FUNCTION, AND AND CHANGE INPUT TO ANTENNA, EVEN WITHOUT SELECTING INPUT FUNCTION WITH THE LG REMOTE FIRST.

It could be that the remote control for your box  is using the same command as the LG TV?
