Official 2011 Mitsubishi Laservue L75-A94 Owner's Thread - Page 23

post #661 of 733
Can someone be kind enough to advise contact details of person that can come to Forest Hills, NY 11375 to do full calibration of Mitsubishi Laservue L75-A94.
I purchased this TV last year in December 2011 from Walts.

Ugh! I just ordered this monster from Walts on Wednesday. I've got a bad feeling about this. Here's hoping there are no problems.
post #663 of 733
Good luck - my Laservue arrived in perfect condition from Walt's even though one out of two pair of 3D glasses were damaged. Kevin at Walt's asked for a pic of the damaged glasses and I'm assuming they will replace them.

Can't say I'm "blown away" by the 3D (watched Prometheus)...and I think I need to tweak the TV a bit...but overall I am very pleased with the picture, especially the size of it for the price.

My 42" Sony Bravia has a sharper picture but that's because it ain't as big!
post #664 of 733
OK. The set has been installed since Friday. It arrived on Thursday with no apparent damage and I had to wait for a friend to help me get it in the room!

Anyway, first impression... WOW! What a bump up from my 53 incher!

Then a few things started bothering me. I believe somewhere in this thread these issues may have already been talked about, but I can't remember where exactly. Anyway....

First off... There seems to be some kind of texture on the screen. Most noticeable when there is a lot of white. But I am noticing it more and more in big blue skies and anywhere where there is a lot of a solid color. When I turn or move my head, this grainy type texture seems to disappear. But I cannot watch a movie while constantly moving my head. I think maybe one or two other folks have talked about this... I am starting to find it very distracting. Has everyone noticed this or just some folks? I have a lazy eye and favor either one eye over the other. I can switch whatever eye I am looking out of, but can't really get both to work together. So, I have pretty bad depth perception and 3D movies do not work with me. I am wondering if this might add to the textured effect. Can you folks with normal vision see this? What happens if you close one eye? Does it become more prominent? I don't even want to ask my wife if she has noticed this. I just spent over 3 grand on this monster after a lot of finagling.

The second thing I find even more distracting. This thing is NOISY! It seems there are two separate things going on. There is a fan, which continues to run for about 30 seconds after I turn the set off and there is also a HUM. The hum I find the most distracting. In quiet scenes it seems that its all that I hear. Is this something that is fixable?

Here's a shot of my setup...


I'm wondering if the enclosed area is pushing the noise out toward me? I've heard some folks mention the hum issue and others say that they don't hear it unless they are right next to the set. not much can be done about the room. Its on the small side. 12 feet wide by 14 feet deep. The main viewing position is about 10 feet away.

Anyway, as you can tell, a lot of my initial excitement had faded after seeing (and hearing) this set in person. There was nowhere to go locally to check this out, so I just had to go by reviews. And the ones I read at the time were saying this set was fantastic. If I had seen this in person, I'm not sure that I would have detected either issue anyway.
post #665 of 733
Was over at The Home Theater forum site and after some discussion it appears that the texture that I am seeing is known as the "Silk Screen Effect." Something that I hadn't heard of before and I guess is common with DLPs. Wish I had known that going in!
post #666 of 733
Every TV has its artifacts. Get something else and you'll have screen door effect, screen clouding and whatever else.
You just have to decide which artifacts are with putting up with.
post #667 of 733
I have L75-A91 LaserVue and am curious what's it would sell for used? I have enjoyed it for 2+ years, but am thinking about trying something new. I paid nearly $5000 at the time for the TV with 4 pairs of 3D glasses. I don't see any in the classifieds or on eBay, so I wouldn't even know where to start for listing it at?

Thank you!
post #668 of 733
It's hard, in one sense, to compare as the Laservue, if I understand correctly, has not been calibrated. I wonder if there is a reference tool to see how closely each set comes close to an ideal.

Given this, the two displays, as currently set up, seem to emphasize different
parts of the color spectrum. The Laservue shows a lot of detail in the shot of the eye...more than the Kuro, but the color balance is different.
post #669 of 733
For the first time renting a blu-ray it came with 3D option. This was Dredd. So I for the first time set up to watch in 3D. Laservue A94
Non motion shots and motion into or out of screen were great, but lateral motion even people just walking across the screen were unwatchable it was so bad.

Any idea if this is the particular movie or a limitation of the TV

Will let others with more technical knowledge/experience than I chime in, but in my experience it is a limit of the TV and it doesn't have the 'processing power' to handle what it should. 3d with that type of motion, or HD gaming, cause the image to stutter and blur. If you look through the thread, there are some good 3d settings suggested as a starting point which I have found help. Basically, you turn off everything that the TV is doing to make the picture look 'better' (edge enhancement, deep field, etc). You could also try watching the 3d section on the Game setting, which does appear to speed up the processing power a bit and eliminate some of the issues.
post #671 of 733
What do you have the dejudder and deblur settings at (can't remember the Mits official names for them ATM)?
I would think you might need to turn them higher if the side to side motion isn't great.
post #672 of 733
@ tangledweb: Which firmware version are you running?
post #673 of 733
I too have the buzzing whining sound eminating from my laservue. It is the worst in bright scenes, and is only noticible during near silent scenes of movies, or while being used as a PC monitor. I'm begining to wonder if the high frequency component, coupled with the laservues intended purpose of being used with a home theatre, and thus subwoofers, has lead to my recent tininitus affliction.

How many sets are like this? Is this a design flaw, or a defective set?

I used my AVR-100 calibration mic plugged in to my PC to capture the following spectral graphs. It seems to clearly show there is a significant amount of mid and high frequency noise coming from the set. What it doesn't show is the spectrum modulating as the picture changes (it does).

Here I put the mic in the bathroom and closed the door:


This is with the mic on my entertainment console, next to the fan exhaust of the laservue:


This is on the console, just behind the connection panel of the laservue:


Consequently, to the right of my set is a fireplace, angled into the living room at a 45-degree angle, with hard panel and brick, making a nice reflector directly into my room. Now I know the noise is not loud, but I think the ringing is only in my right ear...it is hard to tell. It seems to make sense.

I suppose I also need to take a measurment in the last position with the laservue off, but it is the only diplay I have hooked up to this PC (dedicated 3D gaming rig). The PC is located about 20 feet away, to the left of the laservue, is watercooled and near silent.

Can anyone else who does or does not hear this noise post back?

Thanks,
Jason

I have the older version, but mine does the same thing. It was really bad when I first purchased it. So bad I contacted Mits and made them send someone out. They fixed the more obnoxious of the two noises by replacing, I believe it was, the light engine. However, the high frequency noise remained. And, similarly, the noise changes with the screen brightness. I don't know if it's a power supply thing...it reminds me of the noise aging CRT monitors used to make, only it varies with picture content....

Meh, now the set is having other issues, so hopefully whatever they have to fix this time will kill two birds with one stone.

Fan noise is just another one of the problems with RP inherent in the technology. Here's an interesting page of posts in a JVC thread: http://www.avsforum.com/t/528179/the-official-jvc-dila-z-gx86-owners-thread/630#post_5741568

That's one that I happened to bookmark, but fan noise often comes up in owner threads. The lesson seems to be that the sound can be partly managed by surroundings, the type of stand, layers between the tv and the stand, etc.
post #676 of 733
Fan noise is not really irritating to me, and i don't hear that coming from the LV. The zinging sound of what I presume to be the lasers is very irritating.

Yeah, it's not fan noise. I hear that, too, but I can forgive it. Plus, there's enough ambient sound in the room to overcome the fan noise unless I'm close to the set. This is not fan noise, it's pretty high pitched, it changes with the picture.... And, because it's high pitched, it's annoying and rides above the other sounds in the room, including the soundtrack unless I have the volume up.

Exactly.

I assume the latest as it is connected to the net and has updated itself before. I don't know how I would force it otherwise.

Hello, I bought a L65A90 when they first came out - it's still great - and I want to replace it with the 75" model. Any suggestions on a A91,A94 or A96 ? I know they have stopped making them but the Laservue is such a great display method.

The mods can delete this post, too, when they are done taking care of all three of yours. Just figured I'd let you know openly that I reported this post and all three of your others which are exactly the same. You would have served yourself better posting this just once instead of three times, verbatim, in three different threads as your first three posts ever on this forum since joining hours ago. rolleyes.gif

Sorry about the multiple posts. I have not posted anything to a forum before and I didn't know they were all connected. I didn't expect a hostile responce, only seeking advice. I guess I will go elsewhere.

I think his panties were just in a bunch smile.gif He really didn't need to report the posts, a pleasant reply to your posts would have been sufficient.

Now if you did it repeatedly time after time, well then ........ LOL

I suppose I will apologize, but it is pretty suspicious with all the current ranting by myself and a few others about problems with the set for a brand new poster to come in, and thrice evangelize the Laservue technology in all Laservue threads.... I suppose it just felt...a bit like you were a Mitsubishi shill -- and to be honest, I'm still unconvinced.

post #685 of 733
Update on my (fourth?) Laservue - tech has been out a couple times, replaced the light engine first and now the main DM board. Neither has fixed the issues (strange ghosting white line at top right of screen on many scenes where there is vertical panning of the image, severe stutter on some hi-def content and all gaming), so he is back on the phone with Mitsubishi and if they can't find another solution I may be getting my fifth Laservue...maybe the A96 if they don't have anymore A94s.

At this point, I'm really tempted to try and demand a different model since these have been plagued with issues for me. Given I won't go down in size, considering the Sharp HE LC-80LE844U. I've read through the thread on them here, but anyone with direct feedback/comparison to the LV?
post #686 of 733
Just to let you know, maybe it was a fluke for us, but I feel like the A96 did improve the hardware over the A94. (I can't say why.)

There may not be any feature changes, but it is heavier. So unless they added some lead weights at the bottom, it might be more stable.
I guess some weights at the bottom would make it a different kind of stable too.

Btw, I've noticed there IS occasional jitter/jutter in the Laservues on fast camera moves. I've seen it on a couple A94s and the A96 as well.

I don't know why it happens, I think it was discussed earlier in the thread (something about a possible firmware update that never happened).
I always figured it was a result of the Film Mode/Smooth 120 going crazy. I always keep set to Auto for all inputs, even though the default setting is off.
I'd definitely make sure it was off for any game input since the source isn't going to be film.

It's most noticeable when soft subs or closed captions jerk around a bit on a camera move. I figure it's their image processing crap. And to be clear, it's rare. I might see it once a week if that.

And as I've mentioned to you before, bumping the HPOS up 4 lines fixed my weird ghost line artifact on up/down pans (which isn't vertical like yours).

Hey guys. I just picked up a Demo unit Laservue A94. i got it for a great deal. $1799. I have been scouring internet for as much info on this tv as i can.. Always end up coming back to AVSforums. Anyway a few quick questions i hope someone could help clarify for me.

How do i know my TV set is perfect or at least in good shape? What shoudl be the first thing i do to confirm everything is correct and working?
I feel my eye is not that critical or does not know what to look for. Everyone says this TV has amazing brightness on the internet but for some reason i feel like my demo tv seems kinda dim compared to the 80' sharp etc i see on display. I have the settings tweaked to the calibration settings in this forum for day setting. I had a friend come over with his blu-ray calibration disc so we could tweak it and no one seems to have any complaints everything looks good on the TV. Am i just used to those poorly configured plasmas and LEDs i see at the store that look super sharp and bright compared to my laservue?

I know laservue says it can never fade so thats why i am concerned on if it was sitting as a demo for so long can the ftl lamp or lumanance or whatever you call go down?

I hooked my HTPC up to it and found the text blurry at 1920x1080. So i turned on edge enhance and super resolution which helped quite a bit. still feels like its a little hazy or bloomy looking at black text on a white background. Is that just because its a 75 inch and text won't look clear that big? I feel like an 75 LCD might be better in that regard.

Finally this TV does not use lamps or bulbs. So whats the life expectancy? I read that the A90 when first released had a 50,000 hour life span for continuous use. Is it the same with the A94 or better?

I do really love the idea behind this TV. lasers ultra accurate color. I plan to stick with this TV for a long time. I just want some advice on what i should to improve picture and confirm any doubts that nothing is off or not looking right with my laservue.

I think the reason i bring up the brightness or dimness of my laservue is because i feel like if it was just a little more brighter it would not be so light sensitive.

Anyways Thanks for anyone who takes the time to read my long winded questions. smile.gif

Hope you got an extended warranty.... Especially with a demo unit that may have been on quite a while. There have been two of us with older models that around the two year mark were having issues with light output. I'd guess being on all the time would reduce that time considerably.

Now, you may say, "but mine is newer, maybe it won't have the same problem" and you may be right...but I believe all they changed between these models were the screen gain and maybe a few other little things. I don't think the laser unit itself is any different, and that's where the problem lies. The only saving grace may be that with a higher gain screen, they may have been able to back off on how hard they pushed (and therefore needed to cool) the laser unit. They may have also slightly improved the cooling efficiency. It seems that the general consensus is that heat is what does this unit in, and the poor airflow (due to, supposedly, dust collection in an area not easily vacuumed without disassembling the machine) doesn't help.

So...take that for what it's worth.

Is there a way to pull up the service menu? Someone told me most electronics you can pull that service menu up and see how many hours the tv has been on?

Thats disappointing. I actually think the TV looks good it just seems like it could be a tad brighter. Like the blacks almost seem too dark in some movies i watch and i maty be losing some detail.

So is there way to confirm the light output is the same as a brand new one? I could possibly try swapping the TV out i think another store nearby may have a brand new one. I will have to check.

Someone also told me that lasers use fluid. and this could impact the light output? they told me this in passing no idea if he knew what he was talking about. Can you replace fluid in projectors to make it better?

MENU <3-5-6-4>
CURRENT TIME - total hours of operational use.
Press MENU twice to Exit

If you're losing detail in the blacks, turn up the brightness control. Better still, download the free AVSHD Calibration disk and the Patterns Manual here: http://www.avsforum.com/avs-vb/showthread.php?t=948496 It takes the guesswork out of basic settings.

You can only do a light output comparison if it had been measured when new and would have required a meter.
