I had that on mine for the first few weeks. It seemed like it would hesitate at around the middle a bit until fully opened. It disappeard though after a while.
I fact the lens opening process is the only minor flaw of the projector. It is way too loud and noisy and does not seem to be too well engineered.
Before I used a Mitsubishi HC6000. I will install the 6000 in the cellar of my parents, therefore I put a new lamp into it and so could make a direct comparison with the 550 under the same conditions. My room is rather dark, but not black, the screen is 3 meter wide matte white.
The lamp in the 550 has around 1400 hours on it, the old lamp in the 6000 around 2000. The light output of the 6000 with the old lamp in high mode is way lower then that of the 550 in normal mode (meaning not high mode), the overall contrast on the 550 is also way better overall. With the old lamp the 6000 is unwatchable, even on lower screen sizes.
The new lamp in the 6000 in high mode is maybe a little brighter than the 550 in normal mode and the contrast looks better now, but the 550 is still better in contrast overall and so seems even then brighter. I have no measuring equipment, so that's just what I subjectively observed.
As a result of that I will use the lamp in the 550 until around 2000 hours until I will change it.
So I'm still a happy 550-owner. Over the years I went from a Sanyo PLV-60 to a Hitachi TX-200 to the Mitsubishi HC6000 and ended for now with the JVC 550. The JVC is really the first of all I do not really have anything to complain about.
