   Hi - I'm a newbie here and would apreciate some help if anyone can.
   With the digital switchover here, over the last few months we have diligently retuned our box but today we have lost all but 10 channels. We've tried a factory reset but this doesn't fix the issue.
   Can anyone help?
   Cheers

   Hi and welcome to our forums.

   Do you know which transmitter you receive your signals from?

   Agree, and you will need to search for channels 29, 47, 48, 51, 52 and 54. Did you re-tune after the switch on Wednesday?

   However, I notice that the transmitter is very low power on 5 of the 6 MUXes. The 6th is at 20KW power while the others are no more than 2KW. That strong MUX carries 10 channels, which I don't think is a coincidence.

   When you manual tune, check the signal strength and quality of each channel and report back to us.

   Hi FenderBender......the manual tune didn't pick up any channels and the signal strength is as follows:
   Channel 29 - 63 varying up and down
   Channel 47 - 16 Quality 0
   Channel 48 - 15 Quality 0
   Channel 51 - 15 Quality 0
   Channel 52 - 46 Quality 10 to 50 now 0
   Channel 54 - 16 Quality 0
   Do you think it's the transmitter and we should try again tomorrow?
   Cheers

   Did the ten channels you mention in post #1 come from an Automatic Search? If so they must be coming from another transmitter, or signal conditions were better earlier today.

   You can check this link to see if there are any reported problems for your postcode:

   If the problems continue, perhaps you need to check that your aerial, downleads and connectors are performing.

   #Biggles - yes they all came from an automatic search. I've checked https://faq.external.bbc.co.uk/templates/bbcfaqs/emailstatic/interferencePage
   ...and with our postcode, no problems seem to be reported.
   Totally bamboozled now.

    Find your local ITV region from this link and then see if there could be another transmitter in the same direction as Heathfield.
