Facing TV Problems? Ask a TV Technician.
Hi and welcome to JustAnswer,Thank you for the question and your patience. Should you still need assistance for information purposes only...Initially, have you tried the "renaming" function in the Input Setup menu? RECEIVER / HOME MENU / System Setup / Input Setup / Input HDMI 2 / Input Name / Rename
...or perhaps better yet, can you please re-check p. 43 of the Operating Instructions?
