Hi there I have an aerial in my loft with a 4 way booster providing the TV signal to all 4 of my TV's. My samsung LED has lost all channels,and in the diagnostics section of the menu it says the Signal is 0 and the Bit error level is 2000. I have no problems on any of the other 3 TV's and they all run off the same aerial. I have also put a different TV on the same aerial point and found all 110 channels successfully,and even with the aerial unplugged it still says in the diagnostic area bit rate 2000 and the bar is red all the way across. Is this a faulty set or is there a way to do a factory reset to see if it fixes the Problem. What could of caused this to happen in the first place Any help would be much appreciated.
