VM TV box. No video and audio signals when TV is in online mode

Tuning in

Starting this morning (July 23), my TV hasn't been working properly. Yesterday it worked.

I can see the channels on my TV (see the below screenshot), and I can switch channels. However, there are no video or audio output signals - just a black screen.


All other TV features work as expected, e.g., Netflix, Youtube, etc. I can even watch the ongoing TV shows from the beginning, but when I return to the Live mode - black screen.

I would really appreciate it if someone could help to resolve this issue.

Hi Acus_1984,

You need to check your white coax connections going to the 360 box from I assume a cable splitter because that has the live TV feeds, the guide and apps all run from the network connection to the box.

Can you view OnDemand programmes?

If, as I suspect, the answer is yes, then you're describing a loss of the incoming co-ax signal to your TV360. It is this which carries the broadcast TV channels whereas all other content is internet-sourced. Your home-hub provides that connection, whether over Ethernet or WiFi.

I'm surprised there isn't an error code on the linear channels, though.

After checking all coaxial connections for tightness from the box to the wall socket, try an old-fashioned reboot of the box.

Thanks for your comment. I've just checked this cable - it seems like everything is connected fine. 


Do you know if there is any way to check the connection / co-ax signal status? 

Thanks for your prompt reply.

Yes, I can view on demand programmes - I checked it on a couple of channels and everything worked. The only issue is with online / Live mode. 

I've just checked this co-ax connection and didn't find any noticeable issues. I wonder if there is a way to check the connection status. 

Go to Settings, System, Diagnostics and see what the signal strength reports. I assume that is the coax connection as the internet connection is shown separately.



This can be caused by what appears to be some sort of HDCP error, I have a similar problem myself from time to time. At first I thought it might have been a bad HDMI cable so replaced but didn't solve the issue. Unplugging other devices such as fire stick seems to greatly reduce the frequency of it occurring so it could be caused by electrical noise interfering somehow. AV equipment is increasingly double insulated (no Earth connection) which may not help in this regard.

Fully power cycling the TV (i.e unplugging, not just putting in standby) restores the picture when it happens.

Thanks for the advice. Checked and it seems everything is fine.
