How to Copy NVM Data to/from USB
When copying data to and from a USB memory stick, the folder
“repair” is used. When inserting an empty USB memory stick,
and downloading data to the stick, the TV will create this folder.
When sending data from a USB memory stick to a TV, the
intended data must be available in the “repair” folder.
Note that when copying EDID data to the TV, all necessary
EDID files must be in this folder.
