Ive had 2 42f5300's since june last year, one developed a smudge/dark bit on the panel in the corner. Registered the tv on the samsung uk website on Thursday 6th Feb , got a phone call from samsung 2-3 hrs later, then another call from the tv repair place, they came the next day, did a few tests, faulty panel. Then on Wednesday 12th a man came and fitted the panel in about 20 mins, not bad at all , really impressed by the speed of it all. Anyone else have any stories of repairs? good? bad?
