I wonder if someone could help me with service menu. I can access it but can't move up or down either with remote or with tv buttons.
I also have a problem with upgrading the firmware - the tv can't find the file on usb (fat32 formated) Firmware file is downloaded from Samsung website.
The reason I'm trying to change it is to be able to watch videos from usb, which currently is not possible.
Any help would be greatly appreciated!
