I just talked to authorised panasonic dealer of panasonic show room and later to his senior official on toll free number...when i asked about the VBI & DSE problems of 2012 plasma models ,they straight forward said...there are no such problems...and they have not yet recieved any complaint about that....and later i said ..im buying 50gt50d model...and if i have any such issues...will they replace it....they asked me to brief me to brief the problem ...and then i told them in detail the kind of issue it has...he said then take out the first glass mean Anti glare...and then see....i thought this man is ridiculous...he is trying to convince me with anything that comes in his mind...later i said if i want my money back if i proove is universal...he said i will check & return back....Those who have the problem....report to them from our side...and when that becomes a regular hurdle to him...he will then take some action on it
