2007 Mitsubishi WD-XX73X and XX831 Owner's Thread - Page 251

I got the information from service training and from the sales reps. I was told that TI did not support the combination of the new color wheel and the larger format chip. A large part of what they can do with the DMDs has to do with what TI does. I suspect that they just made a decision based on what was available and ready to go to get the sets to market. You will not find much detailed information. Even getting information about service menu items is like pulling teeth from Mitusbishi, and TI has little available publicly.

Basically, I don't make much of any of it and make my judgements on what I see in the performance and what I can get from the sets when I calibrate them. The 73" sets are clearly inferior to the smaller sets. Sill good, but I would just as soon have a Sony, where in the case of the smaller sets I find a slight edge to the Mits.

Any of the differences, however, can be easily overcome by poor calibration. Any of the top few products in this category could be better than the others when comparing calibrated to uncalibrated (or poorly calibrated) sets.

I respect your opinion on this. I have a 65907 that is near perfect (in fact I had a calibrator come out and he declined to work on it because it was so close to good). However, I do feel that even though the 73" may be "clearly inferior" in your educated opinion to the smaller sets I think that having the extra size accounts for something. Not everyone has your eye for detail and frankly I would rather watch a movie on a 73" screen than my 65907 even though I know the picture is probably better on my old 65".


I assume you meant "good" calibration in your statement above. What do you charge and do you ever come to Colorado?

i've tried searching this thread but i can't seem to find any good info...

I'm looking to get a 65731 or 65732(if available) but i want to know how the xbox 360 1080p is with the hddvd addon. The most info i got was that you cannot adjust the colors since the tv receives the signal as a pc signal, is that true? This is one of the main sources i will be using this tv for.

Any help would be appreciated.

I was just up at Magnolia, again comparing the Sony, Mits and Samsung. All >=70". The Sony seemed to have the best picture, from a clarity and true color perspective, but the Samsung was a very close second. I played with the controls on the mits, but I could not get the picture to be as nice as the Sony. The colors were a bit off and it seemed too bright. Even when I turned down the Brillance, it was not right. There was a scene with a satelite in space with a star background. After turning down the bright, the stars were gone, yet other colors such as the gold of the satelite seemed washed out still. The Mits has the Best I/O front and back, but ultimately it is the picture that is the most important. Based on what I have seen, I have decided to pass on the Mits. Now its a choice between the Sony or the Samsung. THe Samsung is a lot less expensive, and yet the picture seems to be 98% of that of the Sony. I did not attempt to adjust the Samsung, so there may have been some tweaking that could have brought the Samsung to par with the Sony.
However, based on what I have read in previous posts, I'm thinking the Samsung must have the smaller DMD DLP since it does have the 6 color color wheel. And if this smaller DMD does not have true 1080 resolution, but rather the bogus wobulation, maybe I was fooling myself that the picture was as good as the Sony.

I had the same issue with my 65731 after just 1 day at home, returned it back to Store and got a new one, everything has been great since then.

My 8300HD, won't work over HDMI either, but only for SD, if I tune to a HD channel it does it well.

The setting I had on my 8300HD with my LCD with DVI Connector before I got the Mitsubishi was Upconvert-1, so it upconverts all SD to 480p, and shows 720p and 1080i as 1080i, that's the only way I wants it, it prevents the issue of resize manually the image all the time when switching from SD to HD and viceversa, or even worst seeing everything on 1080i, with the damn bars at the sides.

I have called my local Cable company for months now and they most of the times don't even understand what I'm talking about , and the few that knows, can't do anything about it, I think maybe updating the firmware to latest version can fix the issue, but being one of the few reporting the issue, I think I'm out of luck.

Just using Component cables in the meantime, difference in HD channels ar enot that huge, so for now I'm stuck with it.

The PC signal is ONLY if you use the VGA output on the XBox. You will end up without the ability to fully adjust your colors. If you use the component input, you're limited to 1080i (no big deal), but no upconverting of SD DVD's.

I had problems with my TW 8300 box and a tech came out. He told me when TW spec'ed the 8300 box from SA so that they did not put a priority on the HDMI and it is very buggy. They made sure the component hook up was going to perform the best and that the HDMI may work on half their boxes because of software problems. Which confirms what many have already found, use component. I am on the fence as to 720p or 1080i works best for me.

Actually, I meant poor calibration, because OOB the sets have poor calibration and the comparison that most people will make is between sets that are NOT calibrated properly. As such, any of them may look better or worse than the others. Any of them calibrated properly will, of course, likely outperform the others OOB. The reason that I stated it the way that I did is that most people will never see a properly calibrated set.

My rates start at $150 + $75 per hour after initial analysis and depend on how much work you decide your set needs once we see how it measures. Calibration is not my primary business and I do not do "calibration trips" generally. I have had clients in San Antonio, Long Beach, CA, Birmingham, AL, and Dallas arrange for me to come out to do specific work for them, but, it usually has involved more than just calibration. I did make trips to Colorado Springs at one time for other business and to visit some friends in Eagle and Ft. Collins, but have not done so in a few years. A trip at this time would be too costly for one client. There are other calibration specialists in your area or who do make trips for that purpose that would be able to offer services more cost effectively.

Look to my calibration suggesestions for getting it closer without instrumentation. I think the post was #7180. It assumes OOB starting points and will generally be a good start for most people.

Don't misusnderstand the degree of my criticism of the 73". They are fine sets and many people are very happy with them. If you want the size look at the both big Sony and the Mits. Just make sure that you see them after at least doing some user level calibration on several sources similar to what you will be using. You will likely be happy with either. You will find much to like about the new technologies relative to your CRT based set. Regardless of how much you like it, as the CRTs age, you will not get the performance out of it that it had when new. No matter what people tell you, they do age out and no amount of calibration will get it back in total.

I'm having the exact same issue and I know the air is not hot. I even had a fan pointing directly at my TV and still this message came up. I think I am just resigned to call mits and see about getting a service tech or a replacement. Any one have any suggestions?

Thanks!

I assume you mean the problem where the message regarding cooling comes up and the set shuts down. I just serviced one this week for this problem. All I did was re-seat the connectors from the thermal sensor and it has not done it since. Hopefully that solves the problem. The sensor may be too sensitive and/or the placement of the connector near the lamp cage may make any resistance in the contacts worse as the temperature cycles.

I read somewhere that the new 6 color wheel was in relativly short supply, and the larger set would not use it at this time. I wish I could remember where I saw that, If I find it again I will post it.................

I just replaced my jvc 56fc97 with the 57831 and couldn't be happier. What a great tv. I tried some searches for some posted picture calibration settings but found nothing. I have the DVE disk which comes with 3 colored filters for R G B so I can get a reading on those colors but what do I use to get the 3 other colors used in the perfect color adjustments dialed in with? Has anyone used DVE and what were the results? Thanks.

Read post 7180 in this thread, for starters. There is also a thread for settings on these sets.

Try Sourcery's Tweaks...they should get you in the ballpark pretty quickly: http://www.avsforum.com/avs-vb/showthread.php?t=733591

Thanks for the response. I have another question, possibly suited to the Oppo thread, but maybe here. How good is the scaler/deinterlacer of our sets? Is it better to have the Oppo do most of the work, or let the Mits (57731) handle it?

I am just trying to minimize the number of conversions to the data.
For example:

1080i setting: 480i->480p->1080p->1080i => back to 1080p by my set. (4 conversions)
720p setting: 480i->480p->720p => 1080p by my set. (3 conversions)
480p setting: 480i->480p => 1080p by my set. (2 conversions)
480i setting: 480i => 480p->1080p by my set. (2 conversions)

Oppo => Mits

Bonus Edit: Is there a screen onDVE where I can use to compare the different outputs, or is it best I play a movie, like Cars (any certain point?) to compare?

Is this something that I can do or do you think that a call into Mits is the better option? I want to get this taken care quick because it is annoying.

Thanks for the help!!

Call for service. If you have a problem you want it documented incase it is a strange one that is intermittent.

Thanks for the info! It's much appreciated!!!!

By the way, how fast are they with service?

Service depends on the local provider. Mitsubishi has little control over that.

Sunday I got a great deal (?) at a local B&M on a 57732. CC now has the Y-57 for $150 less. Is the 57332 worth $150 more for the color controls and an extra component video input?

In my opinion, yes, but that's just my opinion. Without the extra color tint controls you will never be able to have your set professionally calibrated (not that you would anyway)

Like I'm sure a few others on this thread I have been what some would call a lurker. Using the thread to research and learn from others experiences. It is now time to share my own.

I purchased a 57732 in September 2006 in part supported by some of the posts on this thread, some other reseach and above all my own expirences with Mitsu products.

I then pulled the trigger on calibration of the set after reading of some others very positve experiences with Jeff Meier. I waited patiently for four months until Jeff could return to the northeast. I decided based on the feedback posted here that his services were worth the wait and I was not disappointed with the results.

All I can say is you do not relaize what you are missing until you have your set professionally calibrated. To observe what the settings were OOB and to where they were adjusted to is pheonominal.

I tried to play with some of the settings that were posted here but I agree with others who have posted that settings are unique to each unit.

Jeff is a true gentlemen and someone who will patiently educate you about the technology. He has a true passion for his trade.

For me the prices difference between the 732 and 831 was not worth it. Again my personal opinion. However the earlier post about the difference between the Y model and the 732 yes their is no question it is worth it!

However what ever model you choose (732 or 831), it is worth your time (educational) and money to have the set professionally calibrated. I know Jeff is busy but hope you all have the opportunity to work with him if you decide to have your set calibrated.

Thank you to all the posters who take the time to share information on this forum about the products they purchase.

Color me a believer in professional calibration

P.S. Thanks Jeff for the 4 hours you spent with me on Saturday. It was one of the most educational Saturdays I have had in a while.

Hi,
I'm considering buying the 57732 but am having trouble convincing the wife. We just returned our 1yr old Philips 50PF7220A to costco because of black screen problems. She doesn't want to give up the nice viewing angles of a plasma. So how bad are the view angles anyhow?
Thanks,
Srjo

I have a 65-831 about two months old.
twice in the last week my tv displayed a message that my vents were blocked and would shut down momentarily. I immediately shut it off and then turned it right back on and did not have any other issues.

My home is cool and nothing is blocking the vents. The fact that I can just turn it off and right back on seems like a false alarm.

Has anyone had this problem and what did you do to fix or find out was the cause?

Thank you for the help
Ken

It was my pleasure. Hopefully, you are enjoying the changes to your audio as well.

I'm calling for service tomorrow because mine did again tonight and when I cut it back on the message came up again and it just shut down. I just want this resolved. I'll keep you posted with Mits' response on the issue. The first time I called I was told to reset the TV. But as you can tell that didn't work. LOL

Thanks for your report. Did Jeff (UMR) work on your audio?

I've included your report in the list that is linked at the bottom of my post.

Enjoy.

They are not as good as plasma but I have no beef. I have my couch parallel to the TV about 11' away, love seat to the left at 90 degree angle and chair to the right at a 45 degree angle... all seats have a good view of the screen, leftmost seat on the love seat has a slightly darker picture but still plenty bright. The viewing angles are more limited when you are looking down at the screen, looking up at it is OK since the matching stand is pretty low-profile. Hopefully this helps. I just pulled the trigger on the 57831 a few days ago, and other than the SSE which I find mildly distracting, I am extremely pleased with this set.

Thank you, what a pain in the ass. Sometimes it makes you miss the simple technology we use to have.
