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

I'm sure StevensOnln1 will continue to help 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 Freeview "channel". 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.

I-player is working fine as is Channel 5 and all of UKTV.

bruce tearle: I can't find anything on Google about any issues with All4 on your box. I only have a Humax Freesat 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 Channel 4 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).

As a slight aside, this page gives a list of devices that should get ITVX, updated periodically.

have e-mailed Channel 4 but no response as yet.
connected my laptop via HDMI link and had not trouble getting channel 4.
It's frustrating because the HUMAX/Sansung combination did work in the past. just can't think what I could have changed that is causing the problem.
