Mitsubishi HC7900DW owner's thread - Page 8

post #211 of 990
Will someone please assist me. I have a hanging shelf in my ht, in the middle of the seating area, that is attached to the ceiling (due to walled in duct work). I now have an epson 8100 projector sitting upright on this shelf. The shelf is 70 inches from the ground. My screen is 110" diagonal. The shortest distance to the screen from the projector is 134 inches. The top of the viewing area of the screen is 81 inches from the ground and the bottom of the viewing area is 27 inches. According to the Mitsubishi projector calculator there is no way to place the projector on this shelf and have it project on the screen. Is this correct? Thank you.

Mt 7900 and 106" screen were installed a few days ago and it looks great and is absolutely usable with the lights on but I won't use it with the lights on most of the time.

I had 2 questions:

1. I don't seem to be getting 1:1 pixel mapping from my HTPC over HDMI, is there a way to get 1:1 mapping?

2. I always had my previous projectors connected to my UPS to perform a proper shut down in case of a power failure, I know some devices get destroyed by the dirty power from a UPS, is the 7900 safe to connect to a UPS so I can perform a safe shut down? And is it worth it? How bad is it for the projector and bulb to lose power? Should I connect it to my U{PS?

Thanks

No, it will not be able to sit on your shelf. This unit has a largish amount of offset even with lens shift on. At 130" projecting a 106" image, mine is about 13" from the top of the image to the centerline of the lens.

In our store the 6030 does not beat the 7900 in side by side viewing. The 8000 is better than the 7900.
Thanks for replying. I may go for the 8000 then.
post #216 of 990
Wish I had the funds for an 8000 but feel that I am not alumni with the 7900
good luck with your decision they are great projectors for the money.

So with the idea of replacing just the bare bulb in the OEM housing a few times. Is there a limit to how many times you can just change out the bare bulb? Any real negatives to doing so vs. getting a completely new housing each time as well? I don't mind crimping/soldering on connectors or anything like that, so minor work like that does not scare me at all.

The OEM bulb+housing cost on this projector is a little scary given it's almost half the projector's new cost for 1.
post #219 of 990
Anybody on the bare bulb replacement and continually reusing the original OEM housing?

Also, do you have to use the Mitsubishi emitter for this, or will a generic emitter for Mitsubishi 3D DLP TVs work?

Like this:

post #220 of 990
Don't know about the bulbs but for the emitter/glasses, you can use some standard RF based ones if you splice a wire. The info is in the HC7800 thread in the high-end projector sub-forum.
post #221 of 990
I did some more searching and eventually stumbled upon that. There's a Groupon for this projector for $800 shipped today. Too bad they charge sales tax in TX, but $850 seems a pretty good buy for this with the unknown of how much longer it'll be available.
post #222 of 990
I saw the Groupon but is for $999. Is the same price as from Projector People and they are throwing in a 10' HMDI cable.

Here is the link from Groupon http://www.groupon.com/deals/gg-mitsubishi-1080p-3d-hd-projector-hc7900dw

And is now no longer available according to the page
post #223 of 990
What brand/model receivers are people using with this PJ?

Since purchase - about 8 months ago - the 7900 has experienced a couple dozen intermittent power losses. It's very unpredictable, sometimes going as long as 100 hours without any problems, sometimes twice in the same viewing session. The projector will just flick off (not power down properly), and then 20-30 seconds later the fan will come on for the cool down, like it's supposed to in the event of momentary power interruption, though there havn't been any power outages, and it's also plugged into a UPS that hasn't had to come on yet either. The Sony Black Pearl it's replaced never had a similar issue. But the Denon 3808 loses sound momentarily every time it happens as well, suggesting something in the HDMI connection could be triggering it, assuming when it happens some time of backfeed from the HDMI handshake isn't causing the AVR audio to cut out too. I can't ever repeat it, by replaying the same part of the film, were the power loss occured. But that doesn't necessarily mean anything either, as HDMI signal hiccups from layer changes and such, often don't repeat the second time through - though, that too was an extreme rarity with the Sony Black Pearl/Denon 3808 combo.

Mitsubishi thinks it's a PS3 or AVR setting issue, but they haven't been any help troubleshooting it beyond that, unable to do so much as suggest what settings to look at. As such, I've been pretty much in the dark, turning off this feature and that for the past 8 months, while getting the runaround from Mitsubishi customer support. It's happened once while playing a game on the PS3, but the problem has been overwhelmingly with BD movie playback (old and new releases). I thought I finally had it, between upgrading the Denon AVRs firmware (which had never been updated), switching from PS3 signal decoding to bitstreaming for AVR decoding (something I'd gotten away from about the time studios started watermarking their audio, as I began getting occasional popping sounds when bitstreaming at the time, but not from PCM, supposedly because the PS3's firmware was newer) and disabling any automatic internet connectivity when playing BDs. But after another 100 or so hours it's now started again and there's not really anything left to turn off that isn't integral to the systems performance. So, as Mitsubishi is reluctant to look into it until I've completely ruled out the other components in my system, I'm looking to upgrade AVRs, since the Denon would be the most likely culprit, if it's not a problem with the projector itself. It's probably not the best thing having a 3D capable PS3 and 3D capable projector, with a non-3D capable AVR in between anyway, even though I didn't buy the Mits for 3D.

My shortlist of AVRs include the Denon 4000, Onkyo 929 and 818, and Marantz 7008 for their support of Audyssey XT32. But anyone who's had experience with other models from those brands, successfully paired with this projector, would ease my mind too.

There's a link in the Front Projector Deal for the Groupon.

BHPhoto also has it for $799 and I just pulled the trigger there since there is no tax for me. I feel like it might drop a little bit from here, but I'm getting antsy with the steep price drop in the past couple of months that it will be all sold out shortly and I'll be left wishing I had jumped on it.

I plan on doing a hacked RF 3D E-Star setup since IR stuff seems to have plenty of disadvantages.

I'm using it with an Onkyo 808 and I have no complaints. It's outputting from there into a monoprice 1x2 HDMI splitter and then out to the Mits and a Samsung Plasma. No issues from either my HTPC or my PS4.

You will not be disappointed for sure. 799 is truely a bargain basement price. I gotten mine for 899. I am monitoring the lamp+housing prices on the net to see if there are fire sale soon. BHPhoto is selling for 349 and I hope to grab a unit at under 250 if possible.

I am using IR glasses now and it does interfere with the remotes. I am looking to embark on Estar RF setup soon.

Enjoy!
post #227 of 990
Thanks, I'm pretty excited! My 720P LED PA70G works ok for me for most things, but I do find myself wanting more resolution, higher quality optics, and slightly better black levels more and more often now. I feel the HC7900DW will meet both of those criteria well.


Is there any negative to using the extreme ends of the lens shift for placement? I won't position it such that I'm right against the limits for raising the image up, but it probably won't be far away to make sure the lights in my room don't interfere with anything.
post #228 of 990
$799 is an amazing deal. Is there a reason why the price of this model is discounted so much? I hope is just going out of production instead of it having issues.
post #229 of 990
Mitsubishi is leaving the projector business, hence the steep discount. IMO, they are probably trying to sell of all their units fairly soon so they can then "dismantle" the business unit by year's end.

Read this thread - there are no major issues discussed.
post #230 of 990
Thanks! For a minute I wonder if they are refurbish ones.
post #231 of 990
They're not refurbished unless stated (the Groupon and BHphoto deals are brand new sealed projectors).

Again, Mitsubishi is leaving the home theater projector market, this is their brand new model that they're having a firesale on to get out of the industry.
post #232 of 990
...and before you ask, yes, they are honoring the full warranty period.
post #233 of 990
Just wanted to share my experience with you guys. I ordered this projector last month on the 23rd of December through amazon for $1031 for the bundle. it was out of stock and still is. Received an email yesterday that they Now have in stock and gave me a shipping date. Charged my card same day and then this price cuts happened . 990 new on amazon and this id what they charged. Bhphotovideo for 799 without bundle , amazing deals (a seller on amazon) for 699 box open only . I initiated a chat with amazon and asked them to cancel the order which was not possible as it was processing for shipment. The only option I had was to refuse the package when the guy asked me what would be the price you would pay? With this i told him that $799 is what seems reasonable to me and he accepted. my refund is now being processed and order being delivered tomorrow. couldn't be happier! Hats off to amazon and what a great customer service. Hope the projector does not disappoint wink.gif.
post #234 of 990
So you paid $799 for the projector, emitter and 2 glasses? That's a smokin' hot deal, but obviously YMMV on that! Amazon has always done me right as well, which is why I keep ordering from them even after TX started collecting sales tax.

I hope they maintain that level of customer service going forward!

Yes , $799 for projector emitter and 2 3dgs-78u Mitsubishi 3d glasses. I wanted to cancel and order for $699 from amazing deals ,a seller on amazon store and buy rf emitter and glasses separetely to do the wire mod but nothing beats $799 .Here's the email I just received

Hello,

I've requested a refund of $191.17 to your Visa card.

You'll see the refund on your credit card statement in the next 2-3 business days.

Once processed, you'll also be able to see the refund request here:


Best regards,
Aditya R.

Great service indeed. I'm also hoping they maintain same customer service throughout even though they are not doing so good in terms of profits.

That's a heck of a deal. Just 8 to 10 months or so ago, the best deal around was about 1800 (no glasses) from Newegg. At the time, that was so much lower than everybody else, including AVS, and considering I couldn't find a single local vendor that could get one, (not counting the ebay and amazon marketplace vendors, who were a bit cheaper, but never returned any of my emails inquiring about warranty, so I steered clear), that I even did something I rarely do: splurged on an extended warranty.

The problem I'm having doesn't seem to be widespread that I can tell. I've searched the net and haven't found a single related incident. The only thing I found was a similar switching off problem with a previous Mits model, produced years earlier, that was diagnosed as being related to the HDMI board I believe. Having been transferred to multiple tiers of service support, Mits still insists it's a configuration issue, not a hardware one on their end. I think, if I really pressed, they'd look at it or swap it out. But, though money is tight, I'm rather keen to upgrade the AVR anyway, just to hear the supposedly sizeable difference between Audyssey XT and XT32. The peace of mind from having a fully current AVR is also edging me down the upgrade path, as I think it's been several years since Denon has issued a firmware update for my model, and I'm sure there have been some BD spec revisions since then.

Other than the flicking off problem, which has been much less of a problem since I started tinkering with settings than it was when I first got it, and the fact that, for the life of me, I can't figure out how to get blacker than black out of the display, I'm really enjoying the unit. I've been using SXRD for the last 7 years (something around that). Going back to dlp was a major adjustment. For the first couple weeks I experienced semi-severe eyestrain and headaches. And despite the faster color wheel with 24p, I saw rainbows galore, more than I ever did with the lower contrast projectors I last used. But now, my brain seems to have adjusted, as I can go 4-5 hour gaming sessions without getting a headache. And, while I still can easily see a rainbow if I try to, I don't try to, and I rarely see them with even games and even less with 24p BDs. I sometimes have to remind myself to ignore them with dvd or 1080i BDs, but it's not too hard to do now.

Colors are better than I remember from my previous Marantz and Studio Experience dlps as well. I think the Sony SXRD had better optics, and is definitely on another level in terms of build and feature set - though it's great that the Mits has it's own auto cool-down in the event of momentary power failure, where it cools down the lamp without re-lighting it, once power is restored. Obviously not a replacement for a UPS in the event of a longer blackout, but it takes care of most of the power outages we have here. But the Mits is considerably better where it most counts, in that it produces an all around better picture than the Sony, for those who aren't allergic to dlp of course. I was afraid of the added lumens, since I use a silverstar screen, but it's not too much for it. It actually just seems to be more headroom, so I can hopefully get the full 5000 hours out of a lamp in low mode as advertised, like I was able to get 3000 out of my Sony lamps in low. But, I'm especially fond of how much better black levels are compared to the Sony: They're not just deeper, but they're dramatically cleaner as well, all the while being better defined.

BTW, for anyone who wants a good baseline for grayscale calibration prior to getting a pro cal, assuming you plan to get it calibrated at all, I'd try following Arts posted settings at projectorreviews for the 8000. Mits must have made some firmware revisions with later shipments than the unit Art reviewed, as their suggestions for the 7900 were way off. Their recommendations for the 8000 looked mighty close for my 7900, going by eye, which had the latest firmware as of the last time I spoke with Mits about it.

post #237 of 990
Have you guys had issues with the lumen output? I am on the fence with either the HC7900 or the Optoma 131Xe. Reading the review on Projector Review has me leaning towards the 131Xe with its higher output. But the 7900 have higher contras. I will have complete light control and a 110" screen. Roughly 13-14' throw.

From the review.

"Only one complaint in 2D. I could have used more lumens. I’ve been spoiled. For sports I run about a 98 inch diagonal image. In my dedicated theater with all dark surfaces, and full lighting control, it’s just dandy, but, should I turn my lights on and let in a little daylight, the HC7900DW runs out of lumens very quickly. In situations where I’ve got enough light for a sports gathering of friends, the Mitsubishi starts running out, when a Panasonic or Epson would still have plenty more brightness to compensate.
3D sports (off of DVR), was never quite bright enough for me filling that 98 inch diagonal. With the glasses on, there’s almost nothing in reserve for handling any ambient light.
As long as you don’t have too big a screen, and too much uncontrollable ambient light, the HC7900 is a very good projector for sports and other HDTV. At the 100″ screen size it does just fine. Even though this projector can go up to about a 125″ diagonal in 2D in a proper room, (thanks to its roughly 700 calibrated lumens), it really doesn’t have the muscle to do that in 3D, or to handle a lot of ambient light for sports."
post #238 of 990

I am wondering how better this deal will get?? ( like gambling I guess )

 

 I have been watching projector for a while, do you think this would be fine for 120" screen in a room with ambient light during the day? I thought about adding a HP screen to help compensate

 

I am very surprised that you think this handles the blacks better than the Sony, I have seen the Sony's and I think the blacks look very good. ( Now really excited about the Mitsu)

Unfortunately,  I have never been able to see the Mitsu in action.

 

Sitting, trying to get myself to hit the BUY button!!

Sorry to have not replied you before. I had the same issue with optoma hd33 which I had before connected to denon 2113ci. It only happened thrice in its 500 hours life when I sold it. The guy whom I sold it is on 1000 now and has no problem whatsoever.

Rarely , the projector would just switch off showing the red off light and then semi power on just to let the fans run before turning on again itself after around 30-40 seconds.

I think and assume it is the voltage fluctuation and might have something to do with the avr. I never used it with a ups but still I'm certain it would only happen if the projector receives a sudden drop in voltage. I don't know if a ups also acts as a voltage stabilizer but personally it never got me worried and the projector is still running as it should with its original lamp.
