PROCEED AT YOUR OWN RISK It is unclear that modifying the service menu would affect the warranty of your TV since the service menu is not normally accessed by consumers therefore not listed as a condition that would void your warranty.

- DISPLAY, MENU, MUTE, POWER
- MUTE, 1-1-9, ENTER

I am not a qualified TV repair person. My only troubleshooting experience is with the TV shown (RU7100 2019 Model).

There is no official public documentation of the functions of the service menu.
