I received this error today on both V6 boxes. I have followed reboot etc advice. The issue is it is random channels that produce this error. I have a full package and these are channels I was watching as early as yesterday!!!
Have you looked at Check service status at the top of the page?
You can also a run a test on your equipment from there.
If nothing is showing you could also try the Service Status number 0800 561 0061. This often gives details of more local issues down to postcode level.
You also need to check all your connection, especially the white co-axial cable. make sure it isn't twisted, and that it's firmly connected to the back of your TV box and your Virgin Media wall socket. From the wall socket follow the white cable making sure it's tightly connected to your splitter. If your TV box is connected to your Hub, make sure the white wire going into your Hub is tightly connected and your hub is in the upright position.
If the V53 error still persists then you need to contact the Faults team.
You could try the text messaging service. Just send a text with a description of TV Faults to 07533 051809. Your message will go into a queue and a representative will respond to you as soon as possible.It may take a few days.
You can also call 150 from a Virgin landline, or 0345 454 1111, options 1,1 and 2 (Faults) butbest to call at 8am to avoid call queues
When calling Faults you will go through a series of questions/tests, if that doesn't resolve the problem then call back around 10 minutes later and an agent should pick the phone up.
