Cannot display this video mode. Xbox HDMI

[Agiruze]

Hello, I have a 42pfl4606h and today when i was going to start my xbox nothing happened, all that came up the screen was "cannot display this video mode."
I've tried to use different hdmi cable but it didn't work neither.
I' ve tried it on a different tv and the xbox works totally fine.
I've tried to switch the resolution on the xbox to every single resolution there could be, but nothing works. I've tried to reset the TV and reset the xbox but nothing seems to work.
I want to add that the xbox worked on this tv perfectly until today..
I've been on xbox forums and have done everything there is that can be done through the xbox.
Latest fw is installed.
Would be very happy if you could help me. Thanks.

Hi,

did you also try to switch off the TV completely (main switch, power cord)? Sometimes this is magic ^^
