I have Sky. Last night, I was watching it and my screen suddenly lost picture and went one-third black and two-thirds bright green. The terrestrial channels have also lost picture, but have sound. I can, however, play DVD's. Should I get out tomorrow and buy a new set, or call in the repairman?
Thanks, Evelyn. To be honest, I don't know what kind of TV I have, but I have an update to report. I disconnected the whole caboodle and, when I switched on again, everything was OK! So, all is fine, as we speak, but many thanks for your help.
