Mit's answer was to send a tech to replace the light engine. He and I both agreed beforehand that there was no way the LE would have an effect and that in fact the culprit was a bad screen for whatever reason. The LE was replaced with no improvement so this time Mits replaced the entire display with the next year's (A94) model - very nice of them.

So I'm assuming you can see what I'm describing in the pics and that it is wrong enough to be fixed/replaced??

Now to decide if I want to mess with Mit's techs, return the unit (if possible) or just buy a different brand.

It's a bit of a concern that they have so much trouble getting a good TV out of the factory. How do these things hold up in the long term?

That is up to you. If you can both see it while viewing normal content AND it bothers you then get a new one.

I have left and right side darkness, but this seems to me to be from the back panel narrowing as it approaches the edges. When the screen is a pure color, the shadow being cast from ambient light in the room is obvious. When an actual show is playing, it is not perceptible at all. However, I do NOT have that big shiny halo in the middle of the screen, just gradual and minor edge darkening.
post #606 of 733
Since it was so hard to get a good unit shipped, I've decided to try my luck with Mit's LaserVue 'concierge' service. After making me reset everything (ugh) surprise surprise it doesn't seem to be a software issue. I'm supposed to hear back from them tomorrow.

My only concern was that the warranty for the screen proper is only 30 days and says they can choose to replace it with a refurbished one.

If that's the case I don't know what I'll do. That's pretty crappy.
post #607 of 733
One more thing...
I watched a film with subtitles. In the darker scenes if a subtitle popped up, the whole screen would brighten and when the title disappeared it would get dark again.

IIRC these have dynamic lighting in the form of an iris.
Am I to assume this is a normal artifact or is this atypcial?

Is the iris response speed tweakable or 'it is what it is'?
post #608 of 733
I do not think the TV has a dynamic Iris, which is a mechanical device. It might have something called DeepField Imager which is dynamic constrast feature which is totally signal processing. You can try turning that off.

I had an older Mits that had this feature and the reason I know it is not a mechanical iris is because there is a demo mode that splits the screen in half and one side applies the feature and the other does not. You can't do a demo like that with a mechanical iris. With mechanical iris the effect is all of the screen or none of the screen because it adjusts the amount of light by contracting or expanding the light tunnel.

Mits called the mechanical iris "Dark Detailer".
post #609 of 733
Hmm. No, the DeepField Imager is definitely off. I'd call that more of a dynamic contrast since it seems to push the lightest portion to white and the darkest to black.

This is definitely not that. Like I said when it needs the extra brightness for the white of the subtitles it boosts the overall brightness of the frame. It ACTS like it's an iris or dynamic lighting.

So if there is no Dark Detailer in the LaserVue, then what am I seeing?

I was comfortable getting a replacement screen through Mit's service, but if this is a flaw unique to my unit, it's definitely going back.
post #610 of 733
It is light being reflected inside the unit. For that same reason, calibration adjustments are done with an OSD which has to be turned off before new measurements are taken.
post #611 of 733
Thank you. I can live with artifacts. No television is without them. It's just not knowing which are normal and which indicate a flaw in a specific unit that makes you crazy.

I would suggest that you do not get too crazy about things. Keep in mind NOTHING made by man is perfert, NOTHING made by man has ever been perfect, NOTHING made by man will ever be perfect. If you think the issues are not with-in the nomral variations of the design, you may need to deal with that but if you think it is likely to be with-in the nomral variations, then obsessing about it will only make you sick and not resolve the issue.

It is hard to nearly impossible to tell via typed descriptions whether or not the subtle issues you describe are in the normal ranges. Some people can tell via your pictures on some of the issues but frankly I could not see your issues and that may simply be because my computer and monitor are not up to that task.

I think you should rest until you have the scheduled service call and then deal with the issues.
post #613 of 733
Found a setting on my player. A subtitle Dimmer with various levels and an automatic mode. In automatic it dims the titles proportionally to the overall brightness of a scene so they aren't overly bright in dark scenes.

It pretty much eliminated the flashing problem. Nice.

After 3 phone calls in 3 days to Mitsubishi's tech department, still being strung along with 'we'll call you back.'
Feeling like a needy boyfriend.

Forming bad opinion about concierge service.
Seriously, are you guys really happy with your TVs and Mit's customer service?
post #614 of 733
In my experience, Customer Service was always poor until you got further up the food chain, so to speak. Once you get someone with authority to make decisions, things get way better, as in "bend over backwards" better in some cases.
post #615 of 733
@Augerhandle - Is there a best way to get kicked up the food chain?

Also... yeah, one more weird thing I'm seeing.
I can't find a pattern to when it appears, I've seen it on different sources, HDMI input and component.
It's there whether edge enhancement, Deep blah blah, etc., motion processing, etc. are on or off.

It presents as a shimmering line along the top edge of the screen right at the bezel.
It's most visible in films with a black letterbox bar.

This time I bring you video: http://www.mediafire.com/?6cyecbn3f4dh09b (Less than 1 mb).

Another problem? Tweakable? Common issue? WT heck is up with these TVs?

Patience, persistence, and politeness. Don't take no for an answer.

That appears to be some kind of light leakage or reflection in the optical path. I've never seen it before.

That's what your authorized Mitsubishi dealer should be doing, on your behalf. However, dealers that provide that level of service sometimes charge a bit more, which many people don't like to pay. Penny wise and pound foolish, IMHO.

@RU Geekman - The TV is little more then a week old. I shouldn't be paying anything to have a faulty TV repaired.

6 days later I still get told 'they'll call me back'. Today a manager will call me back.
Yeah, right.

Seriously, if you are considering a LaserVue, forget it unless you are willing to have a warranty-less television.
Mitsubishi seems to have zero customer service.
post #619 of 733
All he's saying is that the better dealers can help get things done when the manufacturer isn't taking care of things the way they should. So it's sometimes a choice of getting the absolute best price from a dealer that won't work with you on warranty problems or paying a little closer to list price to buy from a dealer that will help you out with problems (doing some of the legwork for you and knowing who to contact to make things happen, etc.). I don't think anyone would suggest that you should need to pay anything to get a defective TV that was purchased from an authorized dealer fixed while it's under warranty.

LaserVue #5 arrived today and it is an A96.

First impressions:
  • Box was longer. Took much more shoving to get it into elevator.
  • No image flaws. No light bleeding. Nothing. Yay.
  • Fans are a bit louder. Not a deal breaker, but I couldn't hear the ones on the A94. These are audible from our viewing position.
  • Channel Guide is really gone. Bah. Still have the button on the remote, it just doesn't do anything. Add/remove channel in menu isn't any more stable though.
  • 12 pounds heavier by spec. Now exceeds my table's maximum load by 1.8lbs. I'll risk it, but I wonder what they added.
  • Firmware is shown as v13.04 That means it is possible a future update will remove everyone's Channel Guide. Don't be surprised if you wake up one day and it isn't there.
  • Default aspect ratio is STILL stretch mode. Beware, it can make it look like you have bad geometry or something when it's really just messing with your image.

The GUIDE key still has a function in VUDU. It returns to the home screen.

Switched Digital on cable screws up the channel edit. If you are viewing a digial channel and a new switched digital channels shares the phyiscal channel, the new channel is added to the list, however because you were on another vitural channel at the time, the TV was not able to establish that it cannot receive that signal.

Um... what?
post #623 of 733
Physical Channel the frequency the channel is actual using.

Virtural Channel the number the channel calls itself - not related to the frequency.

Digital physical channels can carry multiple sub-channels, 2-1, 2-2, 2-3 etc. All of these can be on the same physical channel (frequency carrier). The Virtual channel system can rename these sub-channels almost any number such as 2-1, 22-3, 42-42 etc if the head end wants to do this.

Switched digital is designed for cable boxes and is a method to support popular and less popular channels within a limited maximum number of physical channels. The digital channels that are not viewed by as many people (the less popular channels). When a viewer wants to view a less popular channel, G4 as example, that no one locally is currently viewing, the viewer selects it from the guide in the cable box - always shown as 758 for example. The cable box sends that request to the head end. The head end looks at the current load and establishes that phyiscal channel 128 is currently underutalized so puts G4 as a sub-channel on 128 and tells the cable box how to find it now. When the viewer stops watching G4 for an extended period of time and no one else locally is watching, then the head end reassigned the sub-channel space - giving a new sub number - to another low usage channel that someone else has just requested.

The problem is the TV is not able to view these channels in the first place but it is able to establish that a new virtual channel number has been sent on a physical channel so it adds that to the list of channel.

When you are in the TV's channel edit screen you see the virtual channel number as the main numbers in that screen, The little gray numbers adjacent are the real physical channel number. You will see that often a lot of sub-channels will share the same physical channel.

I suppose there could be a better way to handle this situation but 75-80% of the American population has cable boxes or satellite receivers and do not see this so this may be low on the priority list.
post #624 of 733
Thanks.

I don't know if that is the reason, but I found on the A94 that the Channel Guide would lock up with some stations. What I was referring to as still unstable is when using the trying to remove a channel with add/remove, you can uncheck some and find you still have it.

A couple channels I had to delete 4 times before it stayed gone. Could be a physical vs virtual channel thing.
But I do think that the ability for some channels to lock up the guide is the reason Mits removed it. I would have preferred that they fixed the problem.

My 70" Sharp LCD just developed a blue line down the side after 8 months of service, so I'm going back to Mitsubishi (previously had a DLP and CRT RPTV). I'm considering perusing the 21 pages here, but anyone have cliff notes to offer? Thanks in advance.
post #626 of 733
Skip it. Their customer support requires dedication from you to get anything done. I've been through 5 TVs now (2 damaged during shipping), and the A96 still shows weird artifacts that the A94 had.

The TV is certainly not worth the price for the quality or the service. Only if you can get it for less than half MSRP consider it.

Just joined AVS...

I am very interested in purchasing the Lazervue L75-A94. Unfortunately, here in Florida there are none to see in person. I have seen youtube videos and read all the user forums. The specs sound impressive. I own an older Mitsubishi rear projection 61" but it is old technology and no HDMI, etc. time to upgrade.

About a year ago I purchased a SONY 43" LCD Bravia for the bedroom. I would buy another SONY for my living room, but they don't presently offer a large enough screen that is in my budget...so I like the Mitsubishi. I have an expensive stand the Lazervue would fit on. Just some questions from you forumers that own one:

Does it have a version of "Motion Flow"...the soap opera effect (which I happen to love)

Is it basically a great picture? Is it a "soft" picture or very "sharp" Does the matte screen affect this? I like low glare screens...

I've read that AlltimeTVs.com is high pressure...but they offer the best price (even though the Lazervue is on backorder) As far as I can tell, they are reputable...

Any insight you can throw my way is appreciated!

The LaserVue doesn't require "Motion Flow" or anything like that because the pixels are are way faster than LCD pixels.

No, I live in Jacksonville. Went to high school in Naples, though! (Way back in the '70's!)
