I have a TV: model 32PFL7685H/12 and serial VN2D1026010503.

Recently I've canceled my cable subscription and am now trying to tune in the antenna channels without success.
When I had cable I had the tv connected to a powerbox via HDMI and all worked fine. Now with the normal antenna connector it simply doesn't find anything.
I've updated the FW today (Q5551-, did a 'Reset to factory' and tried to search channels in all possible ways, without any luck.

The TV has +- 1 year and in the past I have used it with the normal antenna, but it' was not in the same apartment I currently live.
Is there anything I'm missing?
