Hi all, just got my ae700 back from repair again and i was wondering what you all thought of the reported fault. As most of you'll know I have had 2 ae700's that have developed brown staining on the red lcd panel after about 400hrs and on the second unit about 40hrs. I was told that by panasonic that the 1'st unit was heat damaged and they wanted to come and see my install to see why the damage had occured. They never sent an engineer but instead refered me to my new local service agent, he dissmissed the possibility that the install could cause the prob after i described how its installed (ceiling mounted) and suggested I drop the pj at their workshop so he could have a look. After a couple of days he rang me and said that he had seen the fault and informed panasonic of the situation, they had told him that it was a software problem that causes the brown marks and that the pj would have to be sent to them for an upgrade. 10 days later he rang me to let me know he had received my PJ back from panasonic and everything was ok, I picked up the unit and the service note from pannasonic stated software upgraded due to fault, tried it when i got home and the unit as been upgraded to 1.7 firmeware and is fine. Personaly i cant see that the marks were due to software and I think that panasonic are not being entirely truthfull about what the fault was. Anyone encounter anything similar as im sure something would have been posted by now about such a software problem.
