I wonder if someone could advise me here? I have twice had a 'failed' delivery of a Sony FQ80 - both times, they turned up with the set, switched it on, and it had bad 'wavy lines' across the whole picture (even across the menus with no inputs!). The set was VERY cold - but the delivery guys swore that this would not cause such a problem, and so took it away as faulty. Has anyone else had a similar problem? Are they both really faulty (seems unlikely!) or could the temperature be the cause? Advice would be much appreciated! Mark.
