got this tv and tryed with an old remote control to get in service menu,
also enabled advanced menu going to "restore config from usb" and holding on volume up key for 5 seconds while selecting 'advanced' menu item (steps to change microdimming settings)
No way to find something to keep on the pvr after switch off/switch on.
Is there another extended menu and/or a way to enable it?
Thanks in advance.
