Been away came home switched on TV and on the screen I have a picture of a tivo box with a download arrow above it which keeps flashing then goes to the welcome screen then to the starting up screen then back to the picture of the box again tried calling 150 after an hour on the phone get cut off really frustrating asi can't fix the problem and no technical support available paying a lot of money for TV I can't watch
Going by the description you gave it sounds like a failed software update. Have you tried rebooting the box?
You could also try disconnecting the set top box from the mains for 5 minutes.
You could also try this, reboot the tivo and using the buttons on the box hold TV+Down+Record at the same time.
Doing this wipes the drive and reinstalls the tivo operating system
If that fails you could also try signing into Service status at the top of this page? It shows any local faults and you can also run a test against the V6 box. By doing this VM should be able to send a signal to your box and try to repair it, or send out a replacement and/or engineer.
If that doesn't work then I'm sorry to say that you need to contact the Faults team again on 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 hopefully the system will recognise that you've used the online faults checker and place you into a queue for an agent to pick up, rather than going through all the automated tests .If that doesn't resolve the problem then call back around 10 minutes later and an agent should pick the phone up.
You could also 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.
