I have 3 V6 boxes so not a faulty box but noticed this for a while now and seems to be getting worse. bbc news HD, Sky News HD and now some sky movie hd channels. Asks to reboot which makes no difference then asks you to go to /tvcode and enter W02 try to run test and it leads to an error on the page so can’t do the test
I could understand if it was one box but not all 3 exhibiting the same issue. There has been roadworks in the street recently I was wondering if they may have disturbed something. have done network diagnostics and everything seems ok.
