DMTech LM26DT

DM TECH LM26DT Have never managed to get the Freeview to work. It has no easy way to see how to access the Freeview. I cannot get it to tune in to channels automatically since the digital switch. Other TV's find channels using the same aerial but this one cannot find any. On TV setting (as opposed to DTV)but using an odd Line setting I can - via a digibox get some channels, but now not BBC1,2,itv3,4 OR 5. I have tried retuning numerous times. It is a complete waste of space and has caused me a lot of stress. It is too modern to throw and because I didn't choose to try the Freeview - because i was unaware it should have it - until after the warranty expired, I will get no help to fix the problems.What a waste of money. The remote also has a mind of its own and randomly changes the functions of its buttons. i.e. volume will do something else instead.
