Hello to all,
it seems like I messed up my TV by accident..
This is what happened:
I updated my TVs Model C6700 via Service Menu to C6800 and enabled PVR, everything went fine til now.
Then I just wanted to look around and accidentally hit the Enter instead of Exit Button while on Service Menu (yea, yea.. it was dark..) Result was, that my TV performed a factory reset.
After I turned the TV on again it tells me that there are no channels and guess what - I can't scan for channels because "Channels" in the Menu is grayed out (same with Plug + Play)
Internet @ TV, Media Player and HDMI Playback is working like a charm, I just can't scan for TV channels.
Date of purchase has changed to --/--/--
Is there any chance I can enable these functions again?
Thanks in advance and best regards!
C6800 Channels not available after reset

Well it seems like it's working again, thanks to this great board and juuso great posts in the past 
disabling the Hotel Mode worked for me, should've done this before asking you.
