Logik is a brand name used by DSG - who knows who actually manufactures the TV?
I've seen the same call for help on Sky forums as well. My advice is to contact Currys and ask them - after all it is their brand!
From what I've found, the UK Call Centre is on 0844 561 1234 & open Monday-Saturday 8am-8pm or Sunday 8am-6pm.
Just another VM user trying to help, so no guarantees that my advice will work . If my suggestion is helpful, please mark it as helpful; it may help others. Just want to say "Thanks"? That's the Kudos button.
