Official Epson PowerLite Home Cinema 5010 / 6010 thread - Page 42

I read here (5010/6010 thread) many people have the same problem with focus (blur image)
strangely the epson 3010 does not show this behavior.
I suspect bad lens assembly in epson 5010/6010

We do not know whether to blame some bad import or the problem is in all epson 5010/6010 everywhere.
Is there a single holder, where to have the 5010 without any problem in focus here in avsforum. ?

we are not talking about focus drift after a while, but the 30-60% of screen always is out of focus.
We focus the right side, and the left is out of focus and opposite.
I read in avs many have problem with blur image.
I hope this is was a bad batch, we all take the epson at the same time and probably from the same batch.

This will cause the adjustment to go back to default.
Then see if focus is any better.

If you read through this thread, making LCD pixel alignment can make things worse if you do to much, adjust certain areas or use certain increments.

Don Stewart (of Stewart screens) said in this AVSForum thread post that with white walls (including ceiling) "projecting on a light scattering matte white surface the CR [ANSI checkerboard contrast ratio] falls to below 70 to 1."

It isn't easy to take full advantage of the higher contrast of today's better HT projectors including the 5010/6010. Even flat black paint reflects a lot of light. (See earlier posts in this thread for discussion on the best black paint.) Some black fabrics do better.

Addressing Crocdoc's question about ceiling drapes, I can't think of a way to do it that wouldn't look like an Arab tent. Perhaps rotating wood slats (like Venetian blinds) that are painted white on one side and black on the other would work.

Another thought I had was to use beams like this:

Attachment 239792

The side of the beams facing the screen would be painted black or black felt and the ceiling (except that part very close to the screen) and back side of the beams could be light wood like the picture or painted white.

It may take 5 minutes but if there is an issue, it will shutdown.
Doing a forced shutdown using the power switch is not good.

If this happens again, don't shut it off.
Watch the LEDs on the projector and let it shutdown on its own.
Hopefully, the LEDs will tell you something. Watch them closely and make note of the color and flash rate then refer to the manual.

Since I can't paint my ceiling, and I really don't want to modify my ceiling by nailing or screwing into it, what if I used a 45 wide roll of adhesive black velvet cloth? I could get 20 feet of it and put it along the screen wall. Would that make a big enough difference in contrast? I could just pull it down should I decide to sell my home someday. Hopefully it wouldn't damage the ceiling?? I have the fine texture, not the large popcorn texture. I could hang some nicer looking black drapes instead, and hang them on some hooks screwed into the ceiling joists. Any thoughts?

Thanks

Then around 100 hours, it shutdown twice after the loud/superfan activation but I watched the projector LED's and noticed it was telling me the bulb was bad.
I got a new bulb and everything has been fine. No loud/superfan activation.
I'm now at around 40 hours on my new bulb and it's starting again.

I might hold off on getting a replacement projector or bulb just to see if may be this is temp related.
It has been getting colder and I'm wonder if the projector has a sensor on the bulb and if the temp is too cold, it shuts down. (just a thoery).

It seems we are getting a good amount of reports of this high fan activation and 2-3 minute bulb on delay that may be there is a SW or maybe a bulb issue.

Next time you watch a bright movie look around and see where the light is brightest off the walls. Everything I have is flat black in my room, but the reflections off the flat black walls are still pretty noticable in that first 4 feet. With my Vutec Silverstar no light hits the ceiling that I can see. High Gain magic ftw.
If my contractor hadn't stole my money and ran, my room would be 6' deeper and I would mount the screen not on the wall, but just in front of the speakers and build a false wall out of speaker cloth. That would make a huge difference in my room.
