Hi, I've posted on an AE500 bulb flicker thread a few times and had two AE500s with the same problem. I'm in the process of obtaining a refund for the projector. I was going to get an AE700 but this time took some time to check on the experiences of you guys on the forum. Clearly there are some people happy with their AE700s but there are others who are not and I'm minded to consider another LCD projector instead. (FWIW, I was never particularly impressed by the fan noise generated by my AE500 mounted to the ceiling). The Z3 and the new Sony HS50 are the obvious candidates and I've read some of the pros and cos of the the Z3 and the AE700. The HS50 sounds like it may be a step up, but quite frankly I was impressed by the AE500 picture quality and therefore I'm probably going to be just as happy, if not happier, with the Z3 over the AE500. The only concern I have over the Z3 is that it used the same panels as the AE700 and therefore there is a risk of some VB. So, unless I'm truly being paranoid about the Epson panels, the Sony seems the safer, if more expensive bet. However, I use a 70" screen in my front room which has white walls and does not have a black out blind. However, it is rather dingy and the AE500 was ok in low lamp power mode in everything but the sunniest of days, even with the blind up. But will the Sony be just as happy or will I have to consider getting a blackout blind? Its not a dedicated home cinema room so I don't want to go overboard with the home cinemas specific blind etc if it can be helped. I may have talked myself into a Z3 just by typing this Can anyone give me any real world experiences of the Sony and the Z3 in those lighting conditions?
