We were advised that we would have to retune our televisions this morning following changes to the broadcasting situation in our area. We did this but have noticed that we've lost many of the channels we could receive yesterday. Very annoying to say the least! Can you please advise why, every time there are changes to the Sudbury transmitter we lose channels? Our postcode is CM82JS.

Martin Ellis: The most likely explanation is that you're using an older grouped aerial which was not designed to receive the lower frequencies now being used by COM4-6 at Sudbury. If you don't have satellite or cable you should be entitled to have a replacement wideband aerial fitted free of charge, which can be arranged by contacting the Freeview Advice Line (see link below).

Godfrey .Could be you have a groupE aerial . Might be not quite good enough for the BBCB (HD channels) multiplex. A group K or wideband is now needed. If you have no cable or satellite Freeview may be able to provide a new aerial.

Nick Horrex:

You have been told before that Briantist has not updated this website for some time and that he is the ob=nly person who can perform the updates. We regular contributors have no idea as to why he has not done so.

We have also stated that if you want details of multiplex allocations you should put a post code into the Digital UK Coverage Checker.

The fact that the channel allocations have not been updated on this website does not negate the value of it to those having reception problems as we contributors will usually refer them to the Coverage Checker for such information when relevant. Otherwise, we will use our considerable experience to offer guidance to those seeking assistance.

Since the most recent upgrade I have lost all the Multiplex COM5 ARGA Arqiva A channels. I called Freeview who sent an engineer but he could not touch it as the main TV (commandeered by my husband of course) is linked to a Sky box. All the other TVs are freeview. Daughters and I very frustrated. Of course I have tried retune and restart but no joy. Connected to the Sky aerial via a splitter. Any ideas please? Freeview guy suggested 500 worth of rewiring! Thank you Government.

Jo: Check the TV's for signal strength, etc. You havnt included a postcode, so we have no idea what sort of signal you are supposed to be getting, but it could be that Com5 is the canary in the coalmine, and the others are also low signal strength. So check the lot. Next, check you are tunedninto the right transmitter - TVs can lock onto a different transmitter, perhaps much further away.

If the signal is bad on all of them, then its a common cause, so look to where that is - perhaps a failing splitter or dodgy booster power supply.

What do you mean by a Sky aerial? That comes off a dish, so the assumption is that the signal comes off via coax throught the house, fed from either.

If you have no satellite signal, see Sky Digibox says 'No Signal' or 'Technical fault'
