This PJ is not probably that old to have accumulated close to the rate hrs. CT_Wiebe had reported, if I recall, over 3000hrs on his HC5500, although has probably a different lamp. He acknowleded following a strict routine of cleaning the filter regularly (every 100 hrs if I recall). This certainly helps cooling the PJ and lamp by not restriciting the air flow. I had followed this thread regularly and have not heard many complaints about the PJ in general, and the bulb in particular. Hope this holds......

A year is not much, but depends on how many actual hours...I have less than 1400 hrs in about 26 months of usage in low mode....

I will also like to hear from owners their actual experience with the lamp....As I said before...I have not read, prior to this latest ones, reporting lamp problems with the 6800...On the other hand, this PJ is not that old to have accumulated many hours.....

Taking precautions and good care should help.....

I used it for about 2-4 hrs at a time...never for short times or turning it on and off frecuently..

I am relatively new as a PJ owner, so I don't have much experience with lamp issues....I am sure there are much more experienced users that may want to jump in.......

Always allow lamp to cool down properly...I have mine connected to a UPS, though never had a power failure in the middle of using the PJ....for some reason..

Cleaned the filter regularly.....

I just find this recently with similar recommendations..

This might not help the ones experiencing lamp problems already..but it is good advise for future instances.....

I wonder how bright this PJ may look when projecting to a 124 in diagonal screen? I am thinking Carada Brilliant white, 1.4 gain, 2.35:1...PJ at 14-15 ft. from screen...How many FtL image brightness could I expect? Planning on using this PJ CIH capabilities. Anyone with a similar arrangement?

thks in advance

Hi there,
I am nearing completion on my build and I have the HC6800 shining onto a 145 inch 2.4:1 screen with lens. Room is about 18 feet deep. I am more than happy with the image. I do have full light control. However, I have only been projecting onto a white piece of material stretched over my frame. I have some Seymour AV centerstage material ready to go once the rest of the room is finished. Really happy with the film like quality of this projector.
Good luck
Greg

BTW, Currently own the HC6800 with an Elite Sliverframe 100GH1, 16:9, 100 in diag., 1.8 gain, from short throw of about 10 ft., 1400 hrs on low lamp. For the Carada, the PJ will be about 14-15 ft. throw. How many FtL image brightness could I expect? Could I expect a big drop in brightness from my current setup? I would not like a too dim image...

By lens, did you meant anamorphic lens? I heard that would provided more brightness than just using the 6800 built in CIH capability. I guess you would be running in High Lamp mode? How old/hrs on your lamp?

Thanks for your reply

Hi there Mariokrt64,
My projector is pretty new. Only about 100 hours on it. I have an Anamorphic Research 2 prism lens which is great value and I keep the brightness. Low lamp mode is fine for the great majority of films. I do watch on high power occasionally and it gives more pop. I am hoping that with my 1.2 gain screen material I will be fine for low level. If not, no biggie. Only a few hundred for a new lamp after 2000 hours. That's good value!

I see..your lamp is probably pretty bright still......and the lens should definitely help..from what I have read....How good is the scope image with the lens?...how is the lens performance?...Is that an expensive lens?

My lamp is a bit less than 1400 hrs..and still lights up my screen preety good in low lamp....1.8 gain....I don't know, but 145 in screen looks pretty big to me....I am concerned that mine could be underpowered for a 124 in, 1.4 gain Carada....

Can you provide a link for lens vendor/mfr....

thks..

Hi Mariokrt,

http://www.anamorphicresearch.com/products.html

I have an earlier version of the AR2 lens with the astigmatism correction lens (not installed yet). I do get some pincushioning from such a large image but this is easily accounted for in a frame. For what you pay, I think they are really great value. Yes, you will get better performance from a 5,000 dollar lens but they charge less than 1. Have a chat to Randy there... He has been a fantastic support. I also purchased the lmap and sled which has made installation easy. They even supplied a discounted Chief RPAU mount. Great guy to deal with.
Cheers
Greg

If I decide to go with the scope screen..I would have to use the Mitsu CIH capabilities for the time being...can't afford the lens for now due to other priorities..It would be great if I can do it in a not to distant future...Scope movies should look great w/o bars....Let see how it goes with the built in CIH and will go from there....

Congrats for your setup....Have you finish your theater?

Hi there Mariokrt, the Mitsubishi should be better than most for zooming. There is less of a brightness decrease when zooming than with other projectors so although a lens is better, zooming is still a good alternative. Mitsubishi have included some fine quality optical components in their lens assembly, which makes all the difference. I am loving the scope screen. Have always watched 16:9 content and put up with the black bars.... No more. It makes an enormous difference to the immersion. As does a 145 inch screen (just over 10 feet wide). Movies are so much better. Just getting two large Danley DTS10 subs dialled in as well. Even more fun!
Room is almost finished. It's all on my build thread. Just waiting for carpet, then fabric lining the walls then a few touch ups. Done. Looking forward to finishing.
Cheers

Ps, anyone on here used the 3d converter from VIP with their 6800? Any luck?

The Mitsu has what have been called an "undocumented" CIH capabilty discovered by some users on this thread..It works digitally, rather than optically w/o an apparent loss of image quality...I have tried it on my current setup and seems to work fine..there are some people that uses this for their CIH setup.....

The black bars are still there, but hopefully they will blend with the dark background and you are supposed to not be bothered by them...all you would hopefully see is the 2.35 image...when you switch to the 16:9, you would have black bars to your left and right side of the screen that can be hidden with a masking (may use vertical curtains that can be rolled in and out). You may loss some brightness with this feature as compared to the lens, and probably some image qualitly?

Just give it a try to see how it compares with your lens setup....This is sort of a "poor mans CIH" setup, just kidding....

Someone mentioned it in July, but I hadn't seen anyone report on how it worked with the HC6800. (Perhaps I missed it; I don't follow the thread that well.)
I am also interested in any reports on the VIP usage with the HC6800 as well. It will likely be a couple of years before I look at getting a replacement to the HC6800 since it is great. I usually run through at least 1.5 bulbs before I start getting the itch. I doubt I will be in any rush until 4K projectors get into my price range.

Anybody here compared these 2?

This projector is very bright. I just ran a light meter test for my 106" diag screen and got 36 foot candles. This is with the projector is low lamp and with my D65k tuning. 36ftc on my screen is 1195 lumens. Find the square foot of your screen and times it times the 36ftc you'll get your lumens. Mine is a new projector with just 150hrs on it.

Pretty bright, I don't know what other reviewers have got. They're usually off half the time and I don't know why.
post #1066 of 1120
WOW..that's a light cannon...PJ Reviews reported 600+ lumens in high mode and 400+ in low, calibrated, if I recall correctly...much lower.. As far as I can tell, mine looks pretty good in low lamp, with a 100 in, 1.8 gain screen, but that's a qualitative assesement, no measuremts....I have less than 1400 hrs in low lamp.....

As you said, reviewrs are off half the time...
post #1067 of 1120
600/400 there you go. Same person got 1000 lumens on the Optoma HD33 while I got 2000 lumens. Their method of figuring lumens must be off.

post #1069 of 1120
I created a super deal getting this HC6800 projector. I bought new at BB for $499 then sold the used HC6500 for $800, net I paid $199 for the HC6800.

The Optoma's I get all the time, I'm their guy for reviews here at AVS. Plus I pass allot of info for AVS letting intrested people know they'll get a great price buying from AVS. Optoma is happy, AVS is happy, I'm happy.
post #1070 of 1120
Just let me know when a great deal is coming that you are not taking...
post #1071 of 1120
We have an HC4000 and are happy with the picture. There's one feature lacking however that drives me crazy-No power zoom. I utilize the 2:35 capabilities and also the vertical position for a poor man's CIH. Varying Blu Ray framing seems to always have the screen centering a tad different, and it would sure be nice to make micro zoom adjustments along with the vertical position. I was hoping the HC7800 would have power zoom and focus, however it does not. The HC9000 being out of my price range anyway, didn't retain the usual Mits 2:35 options and position features. This leaves me to think about either an HC6800 or HC7000, which are discontinued and the tech is quickly becoming old. I'm not really interested in 3D, and have a completely light controlled room. There are a few places that say they have new 6800's and 7000's left, however when pressed for a sale most of these switch and bait businesses don't even have half of what they advertise to actually sell. Am I crazy to even consider one of these older models over my HC4000 just to have power zoom and focus?

I have seen both selling on ebay...If you go this way..make shure whom you are dealing..check credentials and feedback...There was one selling on the clasifieds on this forum for $1,400 with an almost new bulb...However, just checked it for you and it indicates local pick up only..if you are interested, may want to contact and make an offer to convince to ship it.....

From what I have read, the HC7000 has better blacks but less brighteness...I own a 6800...very reliable PJ....

Good luck with your purchase....

There's 1 place I found with a new 6800, and a couple Mits factory refurb 7000's. All the ebay sellers and a few others that advertise new 7000's don't actually have anything in stock that they have listed-Bunch of scammer/bait and switch places out there I'm afraid. Funny thing-Even after they tell me that they can't get these projectors anymore, they still leave their auctions and website listings up!
post #1074 of 1120
If you can get a deal near to what "Guitarman" got, go for it...at least if you can get a 6800 for less than $1000 or at low '1000's with low hrs, will be a very good deal....

Contrary to other PJ's...this one has been very reliable to me..3 yrs next Oct..only cleaned th filter so far..

BTW...I just lost my lens cover a few weeks ago...Anyone knows how can I get a replacement...I tried emailing Mitsu but they won't ship overseas....

Is it possible to mount these PJ's from the ceiling above the top of the screen? Looks like it if you use the offset adjustment. Any big minus to doing that? I have a 10' ceiling and the bottom of my 2.35 screen is about 33" from the floor. I'm using an HC4000 right now which has a huge offset, plus I use the vertical position adjustment to move the lower letterbox bar to the top of the image along with the upper bar.

According to the manual, for a 100 in screen, you may locate it up to 39 in from screen center, 130-209 in from the screen....

Double check it yourself...to be sure...here is the link for the manual...under "Documentation"..

Had my projector for about two years now and am still impressed with the quality of the picture, just lovin' it! Now heres the problem, I just picked up a new Pioneer Elite VSX53 AVR because it has two HDMI outputs, one for my wall mounted TV and one to run the projector with an overlay electric screen.
Problem the projector is having difficulty getting the signal from the receiver, sometimes it works and sometimes it doesn't. I have posted on the receiver forum also asking for help, but for now no solution. The projector worked fine as long as the receiver is not in the loop. When I do get it to recognize the signal from the AVR I can only get the Bluray signal. I have the HDMI control OFF on the receiver and other equipment, but don't know if the projector has a CEC feature. Can't find any info about it. I suspect that it may have something to do with the scaling features on each being in conflict, but really don't hace a clue. Just trying ao get any type of suggestions from others that may have had this type of sync issue! Thanks in advance for any suggestions!!!

Have you tried changing the cable length to the max setting?

To change the cable length go to LANGUAGE under the FEATURE menu. Then put the cursor on Language, but don't press it. While the cursor is on Language press "Auto Position", "Enter", "Auto Position".
That's the service menu-Don't change anything except HDMI cable length.
post #1079 of 1120
I'll give that a try. Thanks!
post #1080 of 1120
I have a similar problem and tried the tip but could not find anything on HDMI cable length.

I think the problem has more to do with the Pioneer than the Mits. If I run my HDMI cable directly from my BluRay I get the netflix and all menus from my Sony and Samsung Bluray players. The minute I try to use the Pioneer for switching The Mits will only display once the bluray movie is ready. No Netflix, menu, nada.
