But we scanned the forums and found that at least UE49MU7070, UE49MU7070TXXU, and MU6409 models are affected.When broadcast towers sent an analog signal, televisions were equipped with an analog TV tuner.After 2009, those signals switched to a digital frequency, rendering those analog tuners useless.Answer: Freeview signal reception is governed by the availability of digital services in your particular area and is usually dependent upon where you live in relation to the digital transmitters covering your area.Key factors affecting your signal reception include the performance of your TV aerial (Is it suitable for digital reception), your geographic location/ orientation to the digital TV transmitter and an unobstructed clear line of site between the aerial and the transmitter (Example - No large hills, trees or tall buildings blocking the incoming signal to your aerial) Viewers situated in main transmitter coverage areas will normally receive a greater number of digital television services including Public Service Broadcasts (PSB’s) and a range of Commercial services like ITV2, ITV4, Virgin, E4, SKY News etc.The only difference is that these symptoms take a very different appearance to the effects that we have seen before on analogue televisions.

From a report: The Guardian has been contacted by a number of owners complaining that the TVs they bought -- in some cases just two weeks ago -- have been rendered useless by an upgrade sent out by Samsung a week ago.

Others have been posting furious messages on the company's community boards complaining that their new TVs are no longer working.

Answer: Viewers thinking about purchasing a new piece of equipment capable of receiving the new digital television or radio programmes should now always consider how they intend to receive their digital signals – You may need a new aerial!
