Well ive had my 700 for about 3.5 months now and have racked up about 850 hrs on it so far. First 400 hrs were fault free apart from some slight pinkish tinging in the bottom corners, most probably due to the excessive amount of lens shift I use (ceiling mounted) so not that bothered as it can only be seen on a pure white screen. 400-500hrs noticed a couple a flickers now and then whilst web browsing, put it down to the iris having a bit of a fit and though nothing of it. 500-550 flickering now very prominent, seems to come in short bursts and then disappears, ring panasonic to tell them and to arrange a repair.550-650hrs somewhere in this region dust contamination starts to appear , seems to be on the red panel as its only noticable on reds , appears on the right side of the screen from the top to about half way down, not heat damage definately dust (lots of it) . 650-750hrs cannot use pj in low lamp anymore flicker is constant (I mean constant like a strobe) and I am fearfull that the bulb will blow due to the constant flickering ,switch to high mode in the hope that it will get me through christmas without dying. 750-850hrs dust contamination on red panel now very bad, on the red screen in service menu it covers most of the right hand side of the screen. So there you have it, an accelerated long term use profile of my ae700. Im sure many of you have read about my problems with previous pj's and a few of you have said that they are not designed to take the stick that I give them , according to panasonic it should not be a problem but it clearly is. I had hoped that this would be my last pj purchase for a while as the complete re-design of the ae700 assured me that panasonic had aknowledged the technical flaws of earlier models (heat damage due to bad cooling , dust contamination etc) but here I am again waiting for it to be picked up for repair. I know I said it was the last straw with the 500 but this really is it , never again will I buy a panasonic projector (even though it is the best on the market picture wise) they are just too unreliable for heavy use, if you only want to use it for a few films per week then fine, if you want to use it a lot (why the hell wouldnt you, cant see the point of buying something and then limiting the amount you use it) then save up and buy a more robust model. Sorry for the long post, just thought everyone would like a look into the future and the possible faults that may occur.
