My 3000's bulb is up to about 900 hours, and maybe it's just my imagination but it seems like in the last 100 hours or so the contrast has just gotten a lot worse. I've already turned off eco mode and might have to start using "normal" mode instead of "cinema 1" as well.
The overall brightness seems fine, but darker areas and shadows seem more washed out than I remember. The only other thing I've changed recently is I went from using Arcsoft TMT2 to TMT3, so maybe it is a software issue.
Are you sending video levels (normal) or PC levels (expand) to your PJ? Is Your PJ set accordingly? See page 43 of the AE3000's manual: HDMI signal level.
When the bulb is getting older, it will loose brightness (blacks will be blacker but whites will be also less bright). You can recalibrate your PJ using the Waveform Monitor built in.
This is better explained in the AE4000's Functional Instructions Manual that you can download here:https://eww.pavc.panasonic.co.jp/pro...E4000U_Eng.pdf
see page 21.

Brightness = black level. Too low and you'll loose shadow detail; too high and blacks will be (more) gray.
Contrast = white level. If it's too high you'll crush detail in bright images (i.e. clouds, snow, etc.).
