Lost HD channels

[PPSbude]

Hi, having had full complement of HD channels (free view) on my smart box, since last October, on  Friday, CBeebies HD, BBC News HD, BBC 4 HD and 4+1HD (amongst others) all disappeared. Previous answers to this problem don't fit, as aerial is external, plus when I switch source back to the TVs own tuner, they are all there. I have now done at least 6 standard scans over last few days as well as 2 factory resets. And the channels won't return. Any assistance gratefully received.

Hi @PPSbude do you have an aerial booster?  It might be worth trying.

Hi 4268, as the tv itself has no problem getting the channels, using the same aerial, I don't believe its the aerial having the problem. But thanks.

Hi @PPSbude,

Is your 'smart' box connected to the internet via WiFi? If so, the Wi-Fi signal could be swamping the incoming DVB-T/T2 (Freeview) signal...

Is your coaxial cable the double insulated type? If not, it could be picking up the WiFi signals 

[PPSbude]

Hi seemoredigital, smart box is on wired connection, don't know about cable but why would cable not be affected by a wifi signal when plugged into to tv direct, only 30cm away from where it would be when plugged into the smart box, but thanks for trying.

@PPSbude  it is because of interference between the two signals.  Can you try turning off your router temporarily whilst you run a channel scan to see if that makes any difference to how many you get?   I am not suggesting you leave it off simply trying to see if a better insulated coaxial would make a difference.

Hi 4268, just tried what you suggested twice, and no change, channels still missing.

I have exactly same issue. Rescanned channels and still nothing. Exactly same channels disappeared. Noticed a few days ago but can't be sure if they haven't been gone a little while longer. Can't see that being a coincidence.

For the last 2 days when I've turned on my TV and Smart Box, after not being used for a few hours, the menu on the screen is mising the whole of the Freeview section.

The menu on screen is the same as a regular NowTV Box. No Live Channel box or TV Guide listed. I've had to reboot the box to get the usual menu back and Freview Channels.

Any ideas what could be causing this ?

For the last 2 days when I've turned on my TV and Smart Box, the Freeview, TV Guide and Last Live Channel preview screen are missing.

The menu screen looks like a regular NowTV Box menu.

I've had to reboot via the menu to get the Freeview part of the menu and channels back.

Also today I've had Freeview channels freeze twice, and whilst listening to the Tune In app the audio went off, with the box becoming unreponsive all three times. I had to switch the power off at the wall to reboot.

Any ideas what could be causing this?
