My 4000 is far more impressive compared to the 2 Sanyo projectors I had previously too. These 4000 lamps look far brighter after 3000 or 4000 hours each. Would be a shame to lose it over a stupid fan.

I just thought to mention that in addition to fans, the internal variable iris, which changes rapidly from frame to frame, is also known to cause noises and/or shut down issues in some aging Panasonics, which can easily be mistaken as a fan noise.

In A/V reproduction accuracy, there IS no concept of "accounting for personal taste/preference". As art consumers we don't "pick" the level of bass, nor the tint/brightness of a scene's sky, any more than we pick the ending of a novel or Mona Lisa's type of smile. "High fidelity" means "high truthfulness", faithful to the original artist's intent: an unmodified, neutral, accurate copy of the original master, ideally being exact and with no discernable alterations, aka "transparency".

Thanks for that info, I'll keep that in mind. It sounds like that hairdryer kind of whirring. Or exactly like a desktop computer fan that's going bad. I've heard many of those in my day.

Just shoot me a PM with your email and I'll send you the service manual (.pdf) I have...parts list included.

Just an update for those with fan error problems in the self-check. I opened up the projector, removed the circuit board on top, then blew the dust out the fan areas as best I could, away from the sensitive components in the middle and lamp. Wasn't loads of dust but enough to see it fly out. Since then the projector has worked fine with no FAN error in self-check, although the whirring noise has returned which only lasts for the first couple of minutes. I expect the fan will eventually need to be replaced but for now it's not shutting down like before so I'm very happy.

I recently sold my PT-AE4000 and have a spare bulb for sale. I bought the bulb when I bought the projector as a back-up. It is genuine Panasonic ET-LAE4000 in original packaging. Let me know if interested and what you would be willing to pay.

SOLD!

Need some help here.

A couple of months ago I got hold of some discounted Atmos speakers. Could come handy some day. Of course sitting there with atmos speaker with no use forces to do sensible thing and order a new receiver. So suddenly I had Atmos. Of course I discovered that not all Atmos movies had an Atmos track, so I needed an UHD player for that. So I suddenly bought an Xbox One S. Now comes the tricky part:

UHD movies down converted looks different from their HD versions. The HD seems to been tweaked to match the 8bit 4:2:0 format. So at first glance they seem to give a little more pop then the UHD version, but the UHD gives a more organic filmlook.

So after much testing I found best result for UHD is color2 and best for for BD color1.

I have some trouble funding good information of the different presets to make the best settings here. Color1 seem to be tweaked after rec709 and color2 for digital cinema. But that's about it.

Screen will be a 125-130" scope format. Room is completely dark. Throw distance will be 16-17 ft.

Any thoughts?
158" scope and 15 feet back and it seems pretty bright. I'm also in a BatCave. Given my last name is Bateman it seemed an appropriate name for the theater.

That's wasn't flying... That was falling with style!

Curious, what did you upgrade to?

I did not upgrade. I have moved to a smaller home and now I just have a OLED 65" tv. I do miss my theater and the 120" screen!

Hello! Does anyone know where an individual could purchase an LCD panel block for a PT-ae4000u? Similar to this one for an 8000u on eBay http://www.ebay.com/itm/Panasonic-Pr...gAAOSwnHZYcU~N

I'd prefer to buy a new one rather than a used one, but if I could be assured of convergence, I'd consider used. I called Panasonic a while back and they didn't want to sell me the part; they wanted me to send in my projector and the estimate to fix the out-of-convergence panels was as much as buying a new projector. I'm wagering I can do this myself if I can find an affordable LCD block somewhere.

Thanks!
