Thanks Smeeg.


I used your 831 settings on my 73732 and they worked great. I will fiddle more as I get used to the set. Meanwhile, I do await what you did in the service menu and could you post the code again. I know posted in here somewhere, but I have not been able to find it.

He said the lense assembly may be radically diffrent on the 831 with either more elements, or higher contrast lenses, or maybe something diffrent then that all together. This is not a reason to not get the diamond especially if it has a better optical block. I am gonna get down to the bottom of this and you can either count on one or two things. One being the website will not say high contrast screen anymore, or two the website will say improved light engine. If I offended anyone here by flaming them before having absolute confirmation from the source I'm sorry. Doesnt change anything for me I"m still getting the 65831 for half price shipped so I could care less.

Parasite, here is what Icaillo said: "The part numbers are the same for the screens, the mirrors, the lamps, and the ballasts".
So, the optical block is different. I thought the 180w Lamp would be different?


Parasite, I would appreciate you getting to the bottom of this. I have a 65831 and one of the reasons for the purchase was the high contrast screen. However, it would pi.s me off if Mits tried to differentiate the 831 but only some 1394 connectivity was different! In any event, to my eye, there was not a lot of difference between the 732 and 831....

If it proves that the screens are the same between the 732 and 831, then I suggest Mits refund the retail price difference between the two units to all who have purchased the 831 to date.

Thanks, Parasite.

Peace.

Great that your getting the TV for half price. Good.......for you.
Most others are/were paying a premium for their 831 and the great plasma like screen they *thought* they were getting. I guess the thing that kind of bothers me here about a lot of your posts is that you went on and on about how awesome the SCREEN is on the 831 is and that it was the "THE" thing that seperated the 831 and made it seem like a large 1080p plasma for a third of the cost etc etc.
At the time you were the only one who actually saw the 831 in person so many relied upon your opinion as a first adapter.
I guess I wish you were a little more clear on your facts before gushing, to be honest the high contrast plasma like screen talk is the only thing that had me interested in the mitsubishis in the first place because it was something the competition didnt have.

I can't believe that any owners of the 831's would be upset after seeing the picture this thing puts out! Myself, like most bought this set sight unseen, and no one has returned theirs because of the PQ. Some members here b!tched that they weren't getting as good a deal as others, as if it was our fault. Hey I have an idea, if you don't like the price: a)don't buy it, or b)wait until the price comes down to your liking. Now people are blaming ONE person for being deceived, even though Mitsubishi states this one huge feature right on their website!! Parasite "went on and on" about the screen..BECAUSE IT IS NICE!! Gdog, if you feel duped, then return your 831 and get the 732. If you don't even have the 831 yet, why are you here complaining?!

Been playing with mine for a couple days. No problems with the remote. The 831 came with two remotes--a large and small one. Do you have problems with both?

I paid way more then everyone is saying for the 732, yet I am extremely happy with it. I cannot imagine a better picture. It is in fact an identical picture as the 831 when compared iwth identical 1080i source material. If I bout the 831 instead and paid even more I would still be in the clouds happy with it even knowing the screens are identical.

In my case, I really like the PQ on my 831. Definitely world class. However, I have always thought the 732 and 831 were pretty close. Very hard to tell subtle differences in stores where the sets may or may not be adjacent, bad feeds, adjustments, etc.

If I now find out that the screens are identical, and therefore the PQ's are identical, then I would have to say I'm p.ssed. Not at Parasite, but at Mitsubishi. Parasite, IMHO, just reported the high quality of the 831--and I totally agree. I appreciate his posts, which I believe were done honestly and in all innocence. But without the Mits marketing hype of the high contrast screen, I would have bought a 732 and saved a few bucks. I certainly like the case of the 732 better than the 831, and the 732 is bright enough!

No way I'm taking mine back now, however. This set is awesome!

The little one works just fine. I can't program the big remote to control my dvd, receiver, and sat box. Are you using the ER emitter thing?

The instructions tells me: (not using the emitter)
1)Slide to device to control (tv, sat, dvd, audio I think)
2)Hold power until it blinks twice,
3)Enter codes
4)Hit power again..

I'm not at home so I can't test at the moment. But is this what people did?

I connected my PC to the DVI input of the PC. VGA analog. The picture is somewhat washed out compared with the PC. Is this typical of analog VGA input to the TV, or am I doing something wrong? Many of the video adjustments that are available for the TV are NOT available for the PC input. Like Brilliant/Bright/Natural. (My PC doesn't have a digital output, darn!).

I'm not complaining one bit. 731, 732 and 831 was right next to each other. I liked the 831 most before even touching the remote and knowing it was the 831. I l loved it even more after playing with the settings on all 3 models. I can't even imagine how good the picture will look compare the 2 after getting this calibritated.

I think the issue is more one of credibility than picture quality. The 831 is awesome. The 732 is also fantastic. If the electronics and screens are identical, then the pictures on the two sets should be able to be calibrated to be equally good. Those of us who sprung for the 831 thought there was a substantive difference to justify the cost differential. And we would start questioning Mits credibility on dissemination of factual information on their sets.

I'm not questioning whether or not the 831 sets have great PQ--I am sure they do--I just dont like being sold or convinced of something that isnt there--I was strongly considering buying an 831 based largely on the screen----I have bought many things based upon "user reviews" of products. Sometimes I have been happy...sometimes not. But to a large degree I tend to trust user opinions more than a magazine or website that may be getting a kickback for a positive review.
Im not blaming Parasite for anything other than enthusiastically reporting mis-information. Which he unequivocally did. Now Mitsubishi on the other hand was flat out deceitful and should be dealt with accordingly. I seriously doubt many people would pay $5-800 extra for a firewire port and an extra remote control.

Seems similar to MYHD at digitalconnection. Other options are around. Doesn't look like that great a deal to me...

Parasite, thanks for looking into this. I purchased the 65831 this weekend, have 29 days left on my 30 day no questions asked return policy. When I looked at the mits all in a line, the 831 was more vivid and did not show the reflection from windows/lights/TV on opposite wall like the 731/732 did. If the 732 has the same screen, optical block, lens and sticker on the speaker (:-)) then I may ask for a refund or exchange for 732. But, the 831 is awesome and the price was within $200 of the 65732 same store. I did get to see the 2nd half of the Redskins game on the new set, very happy camper.

Again, I am going by memory of this thread and of the 732 thread but the following seem valid summaries of the in store comparative viewing posts:

1. Most people thought there was a significant difference between the 831/732 versus the 731, esp re black levels/shadow detail.

2. Most people (though not all) saw some differences (slight to moderate) between the 831 and the 732, some of which are easily explained by the bulb, while others aren't.

I don't accept that the differences were due to feed quality or settings - if that were true then there would be a significant # of people preferring the 732 (i.e., where the 831 was set up poorly or had a bad feed. I have personally observed the 2 sets side by side at 3 different stores, with varying lighting and feeds, but the same settings. At times I felt the sets were equal (1080p/bright lights) and at times the advantage went to the 831. At no time did the 732 look better. Still, I ordered the 732, then changed when I saw the two in a dark room where the whites/face tones on the 831 were superior. As to the difference in depth, that is a closer call but I at times I thought I did see a small difference.

I thought SSE was low on both sets.

It still says high contrast screen technology in the general description. The fact of the matter is, even though it says it for the 831 and not the 732 does not mean the 732 doesn't have it. It's just an implication that we all soaked up and if it is true that the 732 has this screen as well, then it was very clever albeit misleading verbiage.

You guys give manufacturers too much credit if you think that it was clever manipulation. More likely it was poor communication and people not verifying info. More likely just one end not knowing what the other was doing, poor communication, incompetence, or just a misteak.

Uh, they use the same lamp, too. Unless Mitsubishi uses the same part numbers for more than one part, that is.

Umm Astro , I OWNED a 60xbr1, correction: I owned THREE of them, which all had, you guessed it:green blob. And its funny that you then quote the implication that one shouldn't cry when something negative is said about a TV they like, the big difference is that there is nothing negative being said about the 831, it is people that don't own the 831 complaining about the so-called lack of difference between the 2. I don't see any 831 owners with buyer's remorse, I only see 732 owners trying to justify the difference, or lack thereof.
Nice try though

Now Mitsubishi on the other hand was flat out deceitful and should be dealt with accordingly. I seriously doubt many people would pay $5-800 extra for a firewire port and an extra remote control.

Ok let me make this clear as possible. I just got off the phone with my mits rep who just got off the phone with the chief engineer at mits. The screen is different in the 831 for the 57 and 65 not the 73. the part number is the same because right now it is considered a generic part number and they have not shipped out one replacement screen to this point. They are going to change the part number for the screen on the 831 for the 57 and 65, either when the first replacemt one is ordered or by this banter hitting critical mass as it is about to. So to clarify the 57 and 65 diamonds do have a diffrent screen. The diffrence is in the lenticular not the franel. the optical block is also diffrent in the 831 over the 732 and the changes are not cleared to be printed yet because they dont want other dlp manufactures to learn from them. They will change the part number. To those here who questioned me pushing misinfo, let me remind you it was I who went to the top of the food chain at mits and had the website specify the 6 segement color wheel was in the 57 and 65 and 52 only. I said I would get to the bottom of it and I did and the next day they changed the website after I had a talk with the rep on three way call with the webmaster. I told him now if they are printing misinfo that is fraud and a quick call to the engineer set me straight on the facts that it is a diffrent screen "lenticular" and it will have the part number changed to reflect this.

Now I really am confused. The MITS web site says: "Mitsubishi's 732 Series 1080p DLP® HDTVs feature Mitsubishi's 6-Color Light Engine and unique TurboLight150 lamp system."
AND "Mitsubishi's Diamond 831 Series offers the pinnacle in style and performance, boasting the best Mitsubishi picture ever! These 57˝ and 65˝ 1080p DLP® HDTVs feature Mitsubishi's exclusive 6-Color Light Engine and unique TurboLight180 lamp system for unsurpassed detail and vibrant colors."

So they very clearly state that there is a 180w lamp for the 65831 and 150w bulb for the 65732.

So two possibilities. One is that their service and repair manual and part numbers are screwed up. Two is that they have changed the TV's and the web site is full of garbage. I once was heavily involved in a repair parts system and can tell you that both scenarios are entirely possible!

On the screen, MITS has indeed changed their web site. The 65831 now says:"High Contrast Picture" and the 65732 says "....[nothing]...". But the text of the High Contrast Picture is in standard type font, in a set of bolded bullets, which makes it a recent addition or an afterthought to the web site. Maybe MITS is retracting the "high contrast screen" for the 831?

If there is this kind of confusion on the LAMP, which I thought was a clear difference between the models, then heaven knows the confusion on the screens is even greater!

Parasite, we do need some help here. Can you find out from MITS WHAT'S GOING ON HERE?!?

Parasite, Thanks for digging into the info and cleared this up. I never thought you were intentionally pushing wrong info onto us. Matters like this, especially so early in the ball game can be easily mis-informed.
Your info/contribution here is much appreciated by me and others alike.

They will change the part number. To those here who questioned me pushing misinfo, let me remind you it was I who went to the top of the food chain and mits and had the website specify the 6 segement color wheel was in the 57 and 65 and 52 only. I said I would get to the bottom of it and I did and the next day they changed the website after I had a talk with the rep on three way call with the webmaster. I told him now if they are printing misinfo that is fraud and a quick call to the engineer set me strait on the facts that it is a diffrent screen "lenticular" and it will have the part number changed to reflect this.

Parasite, thanks for the clarification. As I mentioned before, I used to work in a large repair parts business and the use of generic part numbers, BEFORE an actual item was assigned to it, was common. (An ugly process that I tried to discourage, since I was in IT, but common nonetheless). So I buy it. They would be smart to fix this asap, however, to keep the noise level down on this forum.
That also explains why the 150 and 180w lamps currently have the same part number. This was just a non-issue.

HOWEVER, WHY DID THEY CHANGE THE VERBAGE ON THE 65831 WEB SITE JUST RECENTLY TO SAY "High Contrast Picture" instead of "High Contrast Screen"? This sounds like backpeddling.

And, thanks a lot Parasite. Its nice to have the voice of reason here. Your posts are highly valued.

Now, maybe even less of a reason the get the 73831 ? No 6 color wheel(even with the larger chip) and no better screen ? What was mitsubishi thinking ?

[quote=PARASITE]Ok let me make this clear as possible. I just got off the phone with my mits rep who just got off the phone with the chief engineer at mits. The screen is diffrent in the 831 for the 57 and 65 not the 73.

Parasite,
Thanks for digging in to all this stuff to clear up the considerable confusion.

My interest in in the 73" sets. Am I to understand that you are saying that the 73732 and the 73831 will have the same screens? If this is correct, than the only difference between them will be the color of the outside of the units? I thought I understood from previous posts that both of the 73's use the larger chips and the 180 watt lamp systems. So if the "high contrast screen" is not being used on the 73831, then the picture quality should be the same between the 73732 and the 73831. Should this be so, I would guess the 73831 will have pretty poor sales, as not many folks would be willing to pay an extra $500 for the piano black finish.
