Some remote functions not working ua 46c6200

[scadran80]

Hi all. Hope someone can please help with my ua46c6200 TV.
A few days ago I activated hotel mode and the extended service menu for a looksie, but I'm quite positive I didn't change anything. However, after returning TV back to normal, I decided to guess some more remote control codes and I must've found one, because the TV now is in an unusual mode.

When the TV is on, it will not accept these remote control functions: number buttons, source button, media play button. And I now need to hold the power button for several seconds to turn off (and this is logged as the IDSECRETPOWEROFF in service menu).

The remote control is fine and the TV is seeing the IR of those buttons, but when TV is on, it will not accept them. I've tried a universal remote etc, no difference. It just won't accept those functions.
However, when TV is off, the number buttons turn the TV on (as is normal operation).

Oddly enough, the TV will perform its standby mode upgrade (which is set to 2 hours later) sooner than the 2 hours after switching off.
It's as if the TV is in a low profile mode or factory mode or something like that. I've been through the service menu and there's nothing been changed and nothing to change that would make any difference.

I need to downgrade the firmware, but I can't do the widget hack because of not being able to use the numbers, ie can't create the 'develop' user.

I've been playing with upnpinspector and have tried the sendkeycode routine in TestRCRService just by trying random numbers, but it does nothing. The setmute,setvolume etc in the other upnp list (rendercontrol) works fine and carries it out on the TV.

Does anyone know codes for the sendkeycode upnp function for the TV?

I've also been trying to get it working through the netcat soap script. The mute script works, but I get an error on my IR script. Maybe someone can help with this please?

hmm... never heard of this behavior..
what is your firmware Name and Version? perhaps there is a 0000 Fw for your model which will allow you to downgrade...
somewhere in ServiceMenu there should be a "factory restet" function also to get back original rc-behavior...
in c-series wiki there is also a link to C6000 series service manual, perhaps there is some reference for special IR-inputs...

info menu mute power doesn`t bring you to service menu?

[andysilent]

did you already try a soft remote (ruSamsungTVCommunicator, SSRemote, Rol's Remote, Gemote...) and does TV accept codes via LAN/WLAN?

[juusso]

What about to exit hotel mode first?
