Hello - I have a Sony Bravia KDL - 55W829B
Since the installation of a firmware update on 18th October the tv works ie there is picture and sound but the screen turns black as soon as the tv is switched on. If left for 5 minutes switched off and on again, the screen/picture is normal. Has anyone else had issues with this most recent update ? Sony have suggested factory reset which I have done but doesn't not solve the issue. It seems too much of a coincidence that the tv was working fine until the update.
