We have lost all ITV channels over the last few days & get the message "No Signal".I have tried reset but made no difference. The aerial is roof mounted. Can you suggest a solution please?

We don't have any digital TV at all in Chelmsford at CM1 2NH on any of our televisions. It's been off for a couple of months now. Checked out the aerial - it's new and it's pointing at London. Tried re-tuning a number of times on all TV's comes up no-signal. When will we get our DTV back?

Bill Kett: The prediction for your postcode isn't great at the moment. It's possible that the level of interference has been steadily climbing as the switchover programme has progressed, both here and abroad, and is now too high for reliable reception.

Still, I'd normally expect break-up rather than complete failure. Check that the aerial is pointing in the correct direction and that all cables are still intact.

You say that the aerial is new. How new? Was there a guarantee? I'd recommend calling out the installer and getting them to remedy it.

David Jackson: Presumably this was a diplexer, combining a Group A aerial pointing at Crystal Palace with a Group B or E pointing to Sudbury? There's no problem diplexing aerials together for digital services. Nothing in the chain is specifically 'digital' or 'analogue' until you get down to the receiver, and usually only the decoder stage rather than the front-end tuner.

Some boxes do get confused with a mixture of 2K and 8K mode transmissions, in the interim period between Sudbury and Crystal Palace switchovers, and it can be difficult to get some boxes to store the services you want at the preferred numbers. Most would likely store Crystal Palace services at the published channel numbers as they are on the lowest frequencies.

CP may be stronger now, but Sudbury shows a slightly higher probability of reliable reception once the switchover programme is completed. Both are ultimately good, though (except Crystal Palace Mux C/Arqiva A drops to 'variable' in 2013, possibly due to changes overseas as the UK programme should be complete by the end of 2012.)

However, you have to wait almost another year for Crystal Palace to switch over, while Sudbury starts in a couple of weeks. That said, only the PSB multiplexes change to final channels and power levels. The COM multiplexes (A/SDN, C/Arqiva A and D/Arqiva B) stay at low power from Sudbury until after Dover switches over in a year's time.

OK Guys, Thanks for the comments. Looks like it's a roof job. My neighbour has exactly the same ariel & both were replaced about two years ago at the same time. He has digital AOK. I even took one of my small TV's up into the loft and plugged in the ariel direct (before the booster) - same - no digital signal. Man arrives Sat.

Just moved to Chelmsford and looking for information about what will happen as part of the Anglia switch over next month.

Will the Chelmsford transmitter be defunct following this? Will the signal from Sudbury be the preferred one? My neighbors have their roof aerials pointed SW, so I assume they're all pointed at Crystal Palace.

I would just like to know if it's worth waiting for the switch over, or whether I will have any luck bunging an aerial in the loft (I know, how long is a piece of string)
