Hi folks,

Have one of these where at switch on, there's a central band of vertical lines, then after a few seconds a central band of horizontal central lines - No sound or OSG - odd one - any thoughts  ?  - Chris.

PS - Haven't taken the back off as it's 'Factory reconditioned' stock from  Ebay some three months ago, with a three month guarantee and security label - guess it went back to China for reconditioning ? Customer is in angry on-line negotiations.
