Just in case you are not sure where to find the information, it should be something like -
All Settings >Programmes >Programme Tuning & Settings >Signal Test
Then select each one in turn.

Chris, post code is SN103ES, Done all that you have suggested , what we have is 32, strength 46%, and channel 34 signal strength 18%. We have a 4G mobile to the north (our signal from is due West correctly aligned) about 1.2 km away and I believe this is having an effect on our .
I have removed indoor amp and connected direct to my LG smart tv, cleared all memory, reset manually each channel, makes no difference. Occasionally we will pick up another channel but pixelation/break up makes impossible viewing.
Now talking to Resolve TV again, they also thought mobile mast was problem and supplied a free filter, they may send an engineer at no cost to investigate. According to their remit they have authority from mobile license holders to resolve any issues due to mast at no cost to user. Will let you know outcome.

Thanks for the postcode, you aren't in any not-spot for the from according to the predictions. UHF & could be the strongest according to the predictions. but there should be very little between them all.

Those Strength figures are quite low BUT it is the figures that go with them that are very important. It would also be helpful to see figures for the other UHF without & with the amp.

Where is the Filter you currently have inserted. It should be BEFORE THE AMP !
At least you are getting good co-operation from restoretv.uk and yes they are responsible for resolving any issues due to from a mobile !

Not really a transmission problem but would welcome any useful advise or indication if other are having similar trouble. Problem is............

Over recent months I have been unable to load via my HUMAX set to box.

Having selected C4 I receive all the pre-programme adverts but then get the 'this is disappointing etc.' screen.

I have tried reset the HUMAX box and resetting which is the channel but with no luck.

I my TV is a Samsung which is to old to receive the ITVX broadcast. Is this why I cannot get C4?

Advice would be most welcome.

Regards

Bruce Tearle

bruce tearle: Do you mean the All4 catchup/ app? If so, it works using your internet connection and has nothing to do with any signals received via your . What model of Humax box do you have? Have you tried or any other apps on the box? Your Samsung TV not being able to get ITVX has nothing to do with the All4 app.

The set top box is FVP-4000T HUMAX and the TV is Samsung. The box and the TV are recognised as not being able to receive the new ITVX transmissions. Both receive TV via external and copper coax .

Currently, there is no problems receiving other .

this gives sufficient information

bruce tearle: As I said, of is not the issue here. What I was asking was whether any of the other apps on the Humax such as iPlayer are working?

I'm sure StevensOnln1 will continue to with your Humax issues (I dont' have one so can't), but I thought it worth commenting on terminology to avoid any confusion.

ITVX is not transmitted, it is not a "". It is a "streamed" service like iPlayer, All4 or My5 and many others you'll find on a Smart TV or Box that has an internet connection.
ITVX will not work on some boxes or TV's with older technology but All4 should continue to work at present as far as I know.

bruce tearle: I can't find anything on Google about any issues with All4 on your box. I only have a Humax box, which All4 was removed from several years ago, so can't check for any similar issues here. I take it your Samsung TV doesn't have the All4 app? My 2016 Samsung 40" got the update to ITVX so presumably yours is an older model. I think your best option is probably to contact Viewer Enquiries via the email address or phone number at the link below and explain what you've told us to see if they have a solution (please come back and let us know how if they manage to solve it).
