Hi wonder if anyone can help. Our TV does not switch on- the lights come on but the screen doesnt burst into life and there is no sound. Previously we would have just rung up Mercury TV and asked them to have a look but have no idea who to contact now. If anyone has any idea about a friendly low cost repair person it would be appreciated. Also if anyone knows why a TV less than 5 years old would suddenly stop working it would be helpful as it is possible that my children might have done something!
