2011 Mitsubishi 3D DLP Owners Thread (740/840 series) - Page 113

If you're 12 feet back then 73 is too small. I'm 9.5' from my 82." Twelve feet you should go for the 92 if affordable or move the seating closer to the screen if that works in the room. BUT, it depends on what you're wanting. If you want any kind of immersion then you need a bigger screen. My distance is the recommended THX viewing distance but it still feels like a further angle than when I sit 3/4 back in a movie theater. If you don't want a movie theater-like viewing angle then size doesn't matter as much. But I don't see why you'd want anything less if it's feasible. A bigger screen only seems so big now because you're not used to that sort of thing in a home. My sister and brother-in-law's 65" Sharp LED looks so freakin' puny now. It's adorable.

As for my matte screen, TV definitely is not a bad unit, maybe something's off with the outer screen, like the dude who applied the matte whatever wasn't paying attention ..Or I'm ultra-sensitive to the matte coating. Wish I could compare it to another in person. The dude who calibrated my TV said it looked normal though..Normal as in yeah he saw what I did, but that's how these TV's are. Some people see things others don't. For example, I've never seen the rainbow effect. But I had a friend come check out the TV and before they even sat down they mentioned seeing rainbows..I tried to see what they did and couldn't.

i think they were full of crap bud,if you see rainbow effect in a modern dlp these days it might only be for a milli second,and i even doubt that. Both the 82 and 73 840s were sitting literally side by side almost touching, one with matte and one with clear,only diff I could see is the clear screen was ever so slightly crisper,but if it hadnt been sitting right next to the other model I dont think you would pick it out as being much better if it were on the other side of the store..It did have MUCH worse glare and reflection though.this store had alot of directional light Im not sure that would be a big deal to me though as I mainly watch tv at night with can lights that i dim a good bit,sunday day time football might be a little bit bad but I could deal with it,Ill be shopping price between these as a much bigger priority than type of screen. The new model 842 has some better features as well,more hdmi inputs and a better type of 3d glasses that are more comfortable and much cheaper.

Has anyone experienced a failed / corrupt firmware update that bricked your set?

My WD-92840 wasn't updating from 13.05 to 13.06 over the net so I DLed the update to a USB stick and followed the instructions to update. Upon booting up (after the "unplug the set and wait 1 minute" step), the picture looked almost like a film negative. I hit update on the picture menu, it didn't improve, so I hit the power button (planning on rerunning the update). The screen turned off, but the green light started quickly blinking. It stayed that way for about 20 minutes and never full shut down. I pulled the power cable, waited a minute, and plugged it b back in. Fast green blinking, again for another 15-20 minutes. Unplugged, insert update stick, plug in, fast green flashing, 15-20 minutes, wash, rinse repeat.

I even went so far as to reinitialize the USB stick and redownload the update, to no avail.

Obviously I'll be calling Mits in the morning, but has anyone else experienced this? Any super-secret troubleshooting or hard reset steps for when this happens?

Regards,

Sad in Las Vegas

Was this an in-store only pricing?

Is it possible to take the outer bezel off without doing anything to the screen, or does the screen come off with the bezel? I would like to take of the bezel, just to see how the screen is held in place, and maybe diagnose from there. But, looking at the service manual, it looks like the screen(s) come off with the bezel as they are attached to it, and not to the TV body. Has anyone tried this?



Looking at this diagram, it seems to me that if they had made the Screen Holders and Spacers wider, thereby necessitating a wider bezel, the holders would have had more of a straightening effect when clamped down. As narrow as they are, they hold the screen in place, but don't really force it into being flat. Yes, that would make the set a bit bigger overall, but maybe only by a couple inches x & y.

I also wonder if you could put some felt spacers between the bezel and the screen to make a tighter fit.

I had exactly the same thing happen on my 82740. Had to have the system board replaced. Call Mitsubishi, they will take care of it. I am also in Vegas. The guy that came to fix mine was very good and showed up right on time. The only problem was that it took a week to get the part to the repair guys.

You can go here to get the dimensions of all the models:

But it seems only the 92" models will have the clear contrast screen:

Clear Contrast Screen (92″ Class only)

That was online pricing,im not sure what in store is,Im going to go to a local pauls tv sometime this weekend and see what they will do as well,they charge tax online in my state cause they have a store here,so might as well see what they can do local

im guessing they made the 80 and 90 inch models with gloss sceens cause they were pretty much always used in dedicated home theator rooms and not your average living room,Now that sharp is doing the 80 inch,its more common place to have a tv this large in a good sized living room with windows and usual lighting. This is prolly why they are making the 80 matte screen this yr....makes sense,the clear screen has major glare in most any lighting other than overhead low lighting.

The Paul's TV online price for the 82842 is $3299 and is no longer available online (only in store), you had $2099 which is closer to Walt's online price for the 82840...just clarifying.

Good observation and point. Plus with more open room concepts in homes now with more natural lighting, I can see now why matte is a growing need and why it is only on the 92" in the 842 series. I guess that if one is going to go for the 92", then they are willing to ensure it is in the space best suited for it.

true,thats what I do,remodeling,I just bought this house and opened up the kitchen dining room area to the living room,where the wall use to be is now where the seating is,makes the room feel alot bigger.when you are cooking in the kitchen you can see a 70 pretty well,a 80 will be even better,but its pushing it,no one with a 90 would be using this in a reg living room situation,Im sure most are in theator rooms or basements with much more space.. We are doing open concept desighns for people all the time,it is deffinatly whats trending right now.

Im wondering how bad the glare would be with a clear screen for sunday football with 4 northeast facing windows on one side of the room,about 10 ft from the tv,thats the only thing holding me back from clear screen 840 model.

The price i got was on the phone with pauls,I assume they were just price matching walts,thats their same price 2099.. What is a better place to deal with pauls or walts?

Getting my 92840 delivered tomorrow. It's going in a dedicated room with controlled lighting. I'll report my findings this weekend. It's replacing a Sony Qualia 70" SXRD, which I hated to see go. The replacement 65929 is a great PQ display, but I wanted to go bigger in the theater space. I've been on AVS for a few years with the Qualia thread and your thread here is likewise very informative. Thanks for all the good info.

Both...if you work them on price and incentives, then you are guaranteed the lowest deal due to price matching/beating policies. I have very high regards for both companies.

have anyone use this new xpand Edux 3 3D Glasses which has Extended White-Light Range supports large rooms
http://www.xpand.me/products/xpand-edux-3-3d-glasses/

I'm looking for my 92840,

oooh.. sounds nice. I want to replace my XPAND IR glasses because they always lose signal during movie (( dont like it. I dont have the mitsu emitter. Only have a half moon shaped 3rd party emitter and it works good only if i put the emitter on a box half way between me and the tv

Wonder if this one works better and if the glasses are phosotshopped or its really that bright

I sit 8-9' from my 82" set and it works great for me. If I could have fit the 92" in the basement, I would have bought it.

Yeah, no one ever says "I wish I got the smaller one". We watch our 92840 from just over 10'. Probably about the same viewing angle you have. Just right for our setup.

I just purchased a WD-73740, a week ago, after a lightning strike fried the HDMI inputs of a 6 year old WD-65732 (never had a problem, no bulb replacements, but would cost $600 to repair). A couple of comments after reading through this forum:

I considered the 2012 WD-73742, didn't see any difference (other than some kind of PC control with the 742) when comparing specs, and got a better price on the 740 over the 742, even though I was told that the 742 costs the dealer less than the 740. I also noticed that the 742 is 15 pounds lighter than the 740. Whether that makes any difference or not (cheaper cabinet, lighter duty power supply?), I don't know. Any comments?

Addressing the popular geometry issue, I notice ( with a critical eye only...I was looking for it) a very slight downward bow of the upper horizontal area, and an even slighter upward bow of the lower horizontal area when watching a Blu-ray disc with black bars top and bottom. Don't notice any geometry issues with 4:3 vertical bars. Gonna leave it alone as is. Many years ago, I built a (Heathkit) front projection TV (red, green, blue CRT's), and spent a lot of time adjusting geometry and convergence onto a 100" flat pull-down screen. I can agree with some of the "experts" postings that there is no such thing as "perfect" geometry and convergence on projection TV's, especially as the screen gets larger....it's more noticeable on the edges and corners. It's inherent in projection technology (pin cushion effect), and the pursuit of "perfection" has greatly improved over the years. My advice, FWIW, is leave it alone and enjoy the beautiful picture, unless it's really out of whack and you're very critical and picky. Even an expert technician can screw it up more by messing with it.

I miss the split-screen function that the old 65732 had.....watching two football games at once. Guess that wasn't a highly used feature, and Mits decided to eliminate it, Perfect Color/Perfect Tint, and Dark Edge.

My 740 came with software version 13.04. I hooked it up (via an ethernet cable connection) to my internet router, and I noticed this morning that it is now the newest version 13.06. It automatically updated via the internet...no flash drive procedure necessary. Funny that the instructions for getting the updated software make no mention (unless I missed it) of the ability to automatically update with an internet connection. Instructions for the older 738 series does mention the two alternatives (internet or flash drive).

A quirk that I saw mentioned in a previous post: Last night while watching a DVD, the TV suddenly turned off by itself, and the green light immediately started blinking (no 1 minute lag time) for about 60 seconds and stopped. I then turned the TV back on, and all was normal for the rest of the DVD playback. I looked up troubleshooting on the Mits website, and they had a comment about this happening. Apparently, if the TV receives corrupted data from a DVD, Blu-ray, cable/satellite, or over the air broadcast sources, it will shut down and reboot during the green blinking light time. If it happens once, or once a month, it is not considered an issue. If it happens more frequently, check the input source (Blu-ray, cable/satellite) and contact the provider or manufacturer to solve corrupted data issues. I'm also thinking that the software update might have come through the internet while watching the DVD, and the TV shut down and rebooted to install it....just a theory. I will monitor this in the future.

Watching 3D via DirecTV or Blu-ray is cool, although the picture is considerably darker when using the Xpand 3DG-X103 glasses. To counteract this, I set up the "Brilliant" picture mode for more contrast and brightness over my settings for the normally used "Bright" mode with 2D. That's the only adjustment I make when going to 3D....everything else is automatic. Your adjustments will vary with preference. I didn't touch "Advanced Picture ADV1, ADV 2" adjustments. On another note, I believe I'm experiencing some symptoms of queaziness and eye strain while watching 3D for more that 1/2 hour. Read the warning in the manual. Never had it happen in the movie theater with passive 3D glasses.

Overall, I'm very pleased with the picture quality and features of the 73740. Best bang for the buck for a giant screen. Any comments to this post?

I watched a couple of movies over the weekend, and the new 73742 looked great. Then, I watched some football yesterday, and was pleasantly surprised to find that the geometry issues really were not noticable at all. I had been worried about the yard lines being warped at the bottom of the screen, but you really couldn't tell without watching REALLY closely (and then missing the actual plays). The Broncos and 49ers looked great, especially after I turned the sharpness down to 9 from its factory setting. I guess I hadn't done any kind of adjustments to the TV input since I've pretty much only watched movies since I got the replacement TV. Really looked great on 'Natural' and 'Low' noise adustment. Can't wait to watch some Patriot games (and maybe "Patriot Games").

I just plugged in my newly delivered 92842 and we were all amazed. The picture is amazing with no tweaking. I looked at ESPN also looking for any signs of the geometry issues in live TV and it was not visible. I will see more when I calibrate later.

the only geometry issues is can see are only when viewing my pc on the tv - and that's with HDMI of ATI Radeon card to Yamaha Receiver.

I have been having trouble posting messages in the 73640 thread on the shutdown subrject. I hope this reply will post properly. I have occasionally seen the shutdown issue. I have isolated it to either and overtemp problem or more likely a spurious power command from the Mits remote. I have a usb fan pushing air into the fresh air intake on my 92840. I also have my Mits remote put away in a dark colored basket not in line of sight. I do not have shutdowns now. If I was a betting man I would bet its the remote as I have only seen the problem during periods where the Mits remote was on a table facing the didsplay.

Since the Mits do not have Optical out (only Coaxial), has anyone every used coaxial to toslink optical converters like this and this? I was thinking of using one, but wasn't sure if I'm wasting my time.

There is no reason these would not work, the quality of digital audio is no different between coaxial vs. optical. Are there a lot of AV receivers out that do not have any coaxial inputs? I have not purchased a AV Reciever in several years but when I did, most had at least one coaxial (except for some inexpensive HIB and Bose systems).

I used one like this before:
http://www.monoprice.com/products/product.asp?c_id=104&cp_id=10423&cs_id=1042302&p_id=2947&seq=1&format=2

Not with this TV but it should work just fine and it's cheaper than the ones you listed.

Thank you. The monoprice one is a great price with a lot of positive reviews.

When your TV shuts down by itself, does the green light start blinking immediately for about 60 seconds and stops (instead of the usual sequence of manually turning it off and 60 seconds later it starts to blink for 60 seconds and stops)? After that, can you turn it back on normally?

My 73640 shut off itself this morning. The green light blinked for a bit really fast, much faster than if I had turned it off manually. It was very strange. I turned it back on after it stopped blinking. It took a little bit for the blue Mits screen to show up. It seems to have worked normally since. It wasn't overly hot this morning and I have plenty of space open behind the vents.

See my post above....#3377. I also contacted the local authorized Mits repair center....I don't think it's a heat related issue. A solid yellow light indicates overheating. When the TV shuts down by itself and the green light immediately blinks fast for about 30-60 seconds, a glitch of some sort is causing it to reboot. According to the Mits troubleshooting website, the most common cause is corrupted digital data presenting itself to the TV from the input source. The TV doesn't recognize it, doesn't know how to process it, and just reboots. Sounds logical, based on computer behavior. My one week old 73740 did this once last week while watching a DVD, and hasn't happened since.

Monoprice sells good stuff and of good quality at best price, i have purchase most of my HT accessories from them. I live close to their warehouse and pick up same day. I have used TOS --> COX which works great, so COX-> TOS will also work gr8. If it doesn't then return back to monoprice without any hassle.

I haven't watched the sequence that closely as it is a quite random event. The screen goes black and I observe blinking and I can only turn it back one after the blinking has stopped. I do know it never has happened with the remote control concealed. It used to happen failry often when the set was new and I had the remote out almost all the time dialing the set in.

I suspected an HDMI CEC event of some kind even CEC off. I had the remote out a couple weeks ago for a few days as I was making some service menu adjustments and during that time I had two episodes of the shutdown in 3 days. It was at that point I installed theUSB fan which I used to run on my 82837 and put the remote away.The TV has played a ton of hours since with the Olympics running constantly all the other programming I watch and preseason football all without a burp.
