Pixelation

Hello

I have an issue with pixelation on 1 of my 2 boxes, and it's only on 2 channels, Discovery and sky history, it maybe on other channels but these are 2 I use a lot. 

It's on live tv and also on recordings. 

 

Can anyone help please.

  • Pixellated pictures on live TV are often the sign of a signal fault. If you've rebooted your box once, then there's likely a fault somewhere, so this will need VM to intervene. You're likely to need either an engineer visit or a replacement box, depending on what VM's remote diagnostics turn up. If only one of your boxes is affected, an external fault is unlikely - try swapping the two V6 around, does the fault follow the box move? Or remain with the in-room cabling?

    Digital TV platforms (including VM) carry channels in small clusters, known as multiplexes. A signal fault affecting one multiplex will affect all channels carried on that frequency, but other muxes will be unaffected. The allocation of channels across multiplexes does not follow EPG positions, and is (to the end user) random. Discovery HD & Sky History HD also share a mux with E4-HD & Sky Witness HD

    Once you know whether the box or cabling is at fault, you should report your fault. 150 from a VM phone, 0345 4541111 from any other phone - choose the options for "I have a fault with my TV service". Alternatively you can wait on here for staff to respond, which may take a day or so.

    Wow thank you for the reply, some of the terms you have used I'm nit understanding but get the gist on what you are saying.

    Thank you for the reply  

    I will swop the boxes later when I'm home, and see what happens.
