Bug sur UE55HU8200

[Alain7800]

Hello
The text is a translation France English (I am in France)
On my UE55HU8200 I can not fit in:
The universal config menu for the SOURCE area.
And can not ACTIVER HDMI in UHD.
At the ignition it goes directly on TNT tuner off I'm sat on HDMI1
In addition, the reset Factory does not work anymore.
Do you have a small idea of a solution?
With thanks

Hello
I think I have not given enough information to have solutions: UE55HU8200 LXZF
T-NT14UDEUC 1301
T-NT14UDEUS 1107
My concern is to no longer have a reset factory and no longer have access to the advance service.
well I hope the information will be more useful
