I have just bought a TV with built in digital tuner. I have connected it to my digital aerial and at first i found all of the channels. When watching the TV alot of the channels were lost. I have searched the internet and found that the channels i were missing were part of specific multiplexes. I then tuned the TV manually and it worked again dfor a while. It has just gone off again (a few hours later) and will not tune. The signal strength for each multiplex channel number are showing at around 60% but still no channels are found. It cannot be because of the area we live in as the other TV works fine. It is connected to another aerial though. I have also tried using a separate freeview box with the same aerial and it still only finds the same channels as the TV. Any suggestions would be appreciated.
