I have an M&S digital TV (yes I know I should stick to their food only), which used to have occasioanal lip-sync problems. Since Sandy Heath went fully digital this had got really bad with all channels (not just Freeview) experincing this. Put this down to a loft aerial but now have an outside one and still a problem, we are 4 miles from transmitter. Called M&S and they wont do anything as Sandy heath has a low signal apparently, however this is on Freeveiw channels only. They said this TV has small less sensitive tuner, are they telling porkies?

KMJ: Thanks for your explanation of aerials, we clearly have a contract one. Delayed response since I couldnt find my way back to section I had posted my original comment!

I am using a small Yagi aerial (7 bars, dipole and simple screen) bought from Homebase and formerly used in loft but now on high pole attached to shed pointing directly at mast (visible). Pefect picture all time from PC-TV tuner (USB widget) but M&S 1906F001 digi TV experiences breakup, bad sync all time, all channels, attentuator makes it worse. As I said, pre full digital not so bad. I suspect 3yold TV is actually rubbish.

jb38: Thanks, I also thought high signal strength might be the problem so I tried the tiny aerial that came with the PC-TV tuner in the M&S set. Result was no reception on freeview and very poor on the main channels (BBC1 etc). The PC tuner actually worked better with this little aerial. Also used an attentuator, variable up to 20dB but this just made it worse. Hence my suspicions that the TV is faulty but cannot understand why it got much worse after digital switchover - we always used it on digital before with limited problems.

KMJ,Derby: jb38: D Lindsey:
Many thanks for all your help. ITV3 is just as bad but BBC1, BBC2 etc are all showing issues and not part of the MUX system? I dont think electrical interference is an issue as there seems nothing close to the set that might emit a signal - timing seems to be random as well. The Murphy 'manual' is certainly near identical to the one I have so that is its origin. I too have found derogatory comments about the set on the web. It seems very likely that the TV is, if not faulty as such, just plain poor quality. I may persue this further with M&S and/or get a better set.

I have to say that your explanation about different aerials is somewaht confusing. Firstly you say that Yagi aerials would not normally be used for new digital installions then further down (under grids) you say that a high=gain Yagi should be used! You talk about signal groups, including wideband, but give no examples of what these aerials look like! How can you identify a wideband aerial!!!
