To those of you extolling the virtues of jumping ship on CRT, I need to let you know that I continue every day to get inquiries from Pioneer Elite owners wanting to save their $5000-12000 sets from the problem Pioneer had with the cold solder joints on their PS boards in the x10 series and half of the x20 series, and their non-Elite counterparts. When I tell them it only costs them $275 to get that fixed permanently and lifetime warranteed, very few decline. The only ones who do are usually those who got theirs for $100 or free, which means that with those guys I have to deal with a completely different mindset vs. those who paid the big bucks for the best equipment available.

These owners who still care about their sets and who are contacting me every day, don't give a rat's *** about the new technologies. They spent huge amounts of $ on their sets, know their capabicties, and - I think justifiably - want to keep them alive indefinitely.

The windfall of having other owners who spent huge amounts of money on their sets now letting them go for peanuts in favor of flat panels these days - usually because of their wives - will not continue forever. For now you can pick one up for a song. Do it, have it cleaned properly and calibrated - and modified too - and enjoy having sizzling, full of depth HD for a fraction of what they paid for it, even after factoring in cleaning and calibration on that pre-owned set you just came into.

I am not saying there are not some great new technologies out there. Not even CRT can beat the million to one contrast ratio of OLED.

But those are still very expensive and as such way out of reach for all but the wealthy early adopters. And some - like OLED - are still not available to the consumer market as a big screen at all.

CRT is here now. It's big and it's faithful. It's smooth, crisp and true to film quality. It lasts. It has depth, and thru the roof contrast ratio.

And for now, while they still exist in nature - in perfectly good working order, at mid lifespan in their service lives (lasting head and shoulders longer than fixed pixel) and haven't all yet been abandoned for not being thin - it's CHEAP!



Hop on it!

I pretty sure Craig removed the lenses but I am not sure what he actually cleaned inside the TV.

Even if he went under the lenses and did the deeper optics cleaning perfectly, they still need it again at 2.5 years later, if you want to maintain a crystal clear light path in your viewing.

By asking obxdriver about his optics cleaning, I was gently pointing out that his Mits, after a period of dust and oil accumulation, will not show its virtues vis a vis his other set. And I wanted the possible new owner to know that what he was seeing was less than it can be. The advice was really for the new owner.

So how many lens surfaces does the 65813 have, and are they glass or acrylic?

You must have read what I wrote about active matrix OLED. The virtue of these "next to come" sets are that they eliminate all the compensatory circuitry that is being used to optimize LCD sets, each of which introduces issues of one sort or another. AMOLED will eliminate local dimming, motion interpolation and motion lag, and polarized light output to name a few.

To my eyes these CRT RPTV sets provide the best, most natural image to the eye compared to what's out there, and they do it with less processing. Elegant designs usually involve intelligent simplicity, not complexity.

As I've said before, I initially looked at mine as a transitional set, but as I look at other displays in the marketplace I continue to be impressed with how well CRT presents a great image, and does it in a way that is pleasing to the eye. None of the sets I've seen out there as of yet have this natural and comfortable image.

But I do think the new A94 Laservue DLP is a very good set...much better than the earlier models.

Will these upcoming large scale AMOLED displays have the same greenish tint problem that is slightly noticeable on our current four and five inch Super AMOLED panels?

Hard to say, since implementation of AMOLED for large displays is so new.

Supposedly there may be a 55 inch in the works, but it will initially be much more expensive than LED/LCD. There may also be an implementation of OLED wherein it is used as backlighting like LED, but the real thing will be be an actively driven emissive screen where the OLEDs become the pixels of the screen.

Compare this with even full array LED backlit LCD where a discrete number of LEDs provide diffused light to backlight the LCD shutters.

Wow! No matter what anyone says, CRT is without a doubt the technology to equal if not beat. And there is only ONE technology that can make that claim, and that is DLP. Nothing looks as good, as defined and still as natural as life itself. OLED or LCD or Elite or Plasma...even CRT itself...is no match for a perfectly tuned DLP. People talk about rainbows with DLP. People are looking at inferior DLP sets. And even at that, it isn't so much inferior as it is deteriorating/defective sets.

No, there is nothing that can match or beat DLP technology. People only make false claims to justify to themselves their technology (and the exorbitant price they paid) is best.

Funny you should mention that, 'cuz I've always criticized DLP for seeming "fragile" at best to me in addition to the rainbows, jumpy refresh image and obvious contrast ratio "thing".

From my perspective, LCD and CRT are "tried and true" technologies with proven track records that aren't going anywhere. CRT just keeps going, and allows people to have HD on the cheap at the expense of square footage in their house and the weight of the unit, wether it is a direct view/monitor, rptv, or epic front projector model. LCD can be a long lasting technology, but not in cheaper quality sets. It has the obvious advantage of being thin, and even though it is criticized for its contrast ratio, this has improved drastically with time, although larger screen sizes and resolutions still carry a hefty price (but this has greatly improved over time as well, and will continue to).

Newer "oddball" technologies that produce images in unique ways like plasma and DLP have caught on a little bit. I haven't actually seen any plasma sets in person besides a crappy 42" WVGA set displaying standard def signal, but I have seen DLP before and like I said above, it just didn't "click" with me. Those fragile moving parts seem prone to failure over time unlike other more "passive" displays.

Like I said before, I think SAMOLED and its practically infinite contrast ratio holds quite a bit of promise once it can be made into screens bigger than 5". Even our CRT RPTV, when displaying a small amount of light graphics or text on a mostly black background causes the dark areas nearby to become "less dark" when you look closely. Even in pitch blackness, SAMOLED has absolutely none of this, and it really is a "miracle in the palm of your hand" to look at with the exception of its very slight green tint.

And this has been yet another "2 Bunny off topic display technology conversation starter non rant". Thank you.

Just to mix it up a bit, DLP is not a bad technology at all. Take a look at the A94 Laservue, which properly set up is a stunning set. Unlike the bulb driven units there is no color wheel. The only moving parts are the DMD's semiconductor micro mirrors, and semiconductors are very reliable. More and more cinemas are moving to DLP projection, based on sales growth.

I think the point is that every display technology has its problems, including LCD, and DLP for that matter. It's also a matter of how things are implemented.

CRT technology, as Bob has pointed out, is tried and true over decades. And ultimately it's about picture quality, not about whether something is the newest on the block. Based on my own experience there is nothing outdated or inferior about CRT RPTV at all. Before I found my current set, which gives up nothing to anything I've seen, I had a Mits 70 inch non HDTV, and after I had the optics clean it was still very watchable after twenty years. How many displays can you say that about?

Okay...so it doesn't do 3D. Bob's 65 inch Panasonic, with its 720p, apparently can with VIP3D.

Super AMOLED+ doesn't have the green tint (since it actually has 3 subpixels per pixel instead of sharing green ones), so at some point in the near future we should see some beatiful sets. Some of the CE companies have demoed sets that weren't more than 5-6mm thick.

Great information, about the subpixels.

The recent breakthrough by Sumitomo Chemical will bring OLED Hdtvs closer.

Well, Mr "pnj314159" drove from Jersey to Va, and took my (now his) beloved Mits WS-65813 and the Lumagen HDQ away yesterday.
He was a very nice and knowledgeable person and the Mits could not have found a better new owner. I am so happy the Craig Rounds calibrated TV/HDQ went to a purist for PQ. He really put the Mits/HDQ to the test before pulling his trigger.

Thanks to all who commented on this sale, and thanks to pnj314159 for coming to get her out of my way.

This really seems like a win-win situation. Both parties happy, and the 65813 gets to see New Jersey.

Exactly. There's nothing "wrong" with those displays, it's good to get into a discussion about it. And in the end, it is ultimately about picture quality, not specs. Just recently, I was asking in another subforum here on AVS about modelines for our CRT RP, and he/she didn't come right out and say it, but the implication was that it was "some crappy EDTV", but I just came right back and told him it was a 3D Full HD TV set.

I like a good argument, but I don't take crap from people like in that other thread. There was also this one time (on a forum about guinea pigs, of all things ), and I had a dying guinea pig that I was hoping I could help to live longer, but instead the playground/forum "bully" decided to go off on a ton of crap about me being an animal abuser and how I should've taken it to a hospital and stuff (which we could not afford at the time), so I came back calmly but very firmly and told him/her my mind and completely pwned the would be "argument". I think sometimes people are afraid to reveal the truth in a situation because they're afraid of an argument, and I'm glad you went ahead and shared your opinion (calmly) and opened this up for us to have a healthy, calm discussion on DLP and SAMOLED and other display technologies.

I guess I didn't really know where I was going with that, but "all that to say" that just because people tell you that it's just some "antique EDTV" doesn't mean it's true. CRT RPTV has that "3D" magic too, so you do get to tell people that it is a 3D Full HD TV set.

Yes. But remember, every design brings potential problems. Flat panels such as LCD potentially can and do suffer banding, dirty screen effect, or mura effect. It's also about implementation and quality control.

So I went to Paul's TV today, just to check out displays, and got into a conversation with a couple of the very knowledgeable salesman who work there... salesman who'd worked for years, at other AV companies. In the conversation I got an answer to my question about the lenses in the 65813, which are also in a few other Mitsubishi models. The secondary lenses are acrylic, but the primary focusing lens is a Nikon glass lens, which is a very high-grade optic. This goes to show you how much quality went into some of these sets.

I have seen the insides of the lens barrel where one of the center lensers is glass while the outer lenses are plastic. Didn't know whether that was done often or not, I have only seen it once, when I had to open up a lens barrel. But good to know!


The last OLED I saw was a Sony, where they were quoting the retail selling price of the 11" version as $2500. That was 3 years ago at CES.

Where I also saw their advanced 27" proprietary model, which was not in production yet, and nobody knew when it would be.

Both sets had 1,000,000:1 contrast ratio and not even a hint of green tint. No OLED I have seen has had even a hint of anything but pure black, and completely transparent shadow detail. Absolutely crystal clear blacks, the depth of which was simply stunning, every time. I was very disappointed that they were making such slow progress at coming up with big screens with that technology.

And that was 3 years ago.

The breakthrough by Sumitomo, posted a few posts back, was quite big, so I think it's highly possible we'll see a 40-55 inch in one to two years. Maybe in 2012.

I'd imagine the glass optic formed the point of focus within the lens assembly, and so a high resolution glass there would really impact image quality.

Nikon has made some very fine optics.

I wonder if the Super AMOLED was what gives it the green tint. In a microscope video and a conversation I had with someone on another board, the SAMOLED pixels share green subpixels. I found a program for my Epic (actually cooked in to the latest Legendary ROM) called Voodoo tweaks, and that lets you have some control over the red, green, and blue gamma control of the screen, and I'd say I've come at least somewhat close to nailing it.

What if somebody bought like fifty Samsung Epics and stuck them to a wall and then used them all as secondary monitors from their computer and then put a video on it? We'd have like a massive 5000x3000something "big Super AMOLED screen" kind of . It must be the concept of actually putting a lot of those small LEDs together in one display that is the challenge, especially with doing it cost effectively.

Good stuff, good stuff.

My guess is anyone who spent $5000-12000 on a tv is totally willing to pay $275 to keep it running regardless of the technology involved. Anyone else just has to look at the marketplace where you can buy a 50" flat panel for $500. Price wins every time and even $275 which isn't much to keep a tv going is enough for someone to decide to drop their CRT and put that money on a new TV. I love my 73" mitts and 65" Hitachi, but when they die I will jump ship and get one of those sharp 80" sets or something similar. Its just easier and more cost effective than putting money in an aging CRT.

I equate CRT's to the muscle cars of the 60's and 70's. IMO there were never any cars built then or now that can compete with them but they are only appreciated by those who know their value and are willing to work on them,everyone else just wants a reliable cheap car.

It's funny that you mention the 80 inch Sharp, as I feel that's a very good display, despite my general disinclination towards LED/LCD
.
I saw it once at BB, and once at Paul's. At Best Buy I liked it better than the Elite, probably because it doesn't have local dimming, which I think problematic. It was easier on the eye than the local dimming Elite. At Paul's I was able to take it down from the brilliant mode to film (Mits doesn't have a THX mode), and both modes looked extremely good.

They were showing Avatar...the non 3D version, as the current 80 inch doesn't have 3D or 240hz...and the image had a lot of impact. Extremely immersive.

Sharp reduced the light bleed by decreasing the pixel gaps, and frankly to my eye the display produced very good blacks without any need for local dimming. It uses an XGen panel like the Elite, with less processing, and...no local dimming.

It's a very good display.

And at the same time there is an enchantment to the round dimensionality of CRT, which has the warmth of vinyl compared to the often clinical sound of digital. LCD is, after all, a digital technology.

I hope to keep my tv sets for awhile longer and let Sharp refine those big sets and perhaps other manufacturers get into making larger sizes. It's inevitable that sooner or later the cost to fix will outweigh the benefit of keeping our CRT tv sets.

Totally agree,when I bought my Hitachi from Circuit city, the salesman kept trying to steer me to a DLP, but I knew what the better set was even under the awful conditions they had the Hitachi presented.

Horizontal lines on 57HX93

I’ve made a brief post about this before. I’m getting a horizontal line that flashes on my display it’s typically red and its constant yet intermittent and it locaiton vairries. It does it most of the time and the frequency in which it happens is not consistent. Also what happens is when it’s doing this the color changes gets washed out.

It does it when the sets just turned on and also why it’s been on awhile. However at times it won’t do it at all or very little.

The strange part about it to me, is it doesn’t do it on antenna inputs. I’ve check both component and the DVI input with multiple sources, (PS3, HD-DVD, DirecTV) and it doesn’t matter which devices on which input, it still does it. I didn't check s-vid or composit. When I watch split screen(AKA PIP) antenna and directTV, it does it only on the veiwable image, its weird when you chage the zoom levels of each picture (making the direcTV really small) it only flashes on that small portion of the screen never a flash on the antenna input or any of the grey area. What board could be going out or have a bad connection? Or any other items to check.

Other than some marks on the screen I’ve loved the picture this set has given me. I still think it’s display when it was working is still better than most display’s I’ve seen.

I'd imagine the glass optic formed the point of focus within the lens assembly, and so a high resolution glass there would really impact image quality.

Nikon has made some very fine optics.

Makes sense -

Price wins every time and even $275 which isn't much to keep a tv going is enough for someone to decide to drop their CRT and put that money on a new TV. I love my 73" mitts and 65" Hitachi, but when they die I will jump ship and get one of those sharp 80" sets or something similar. Its just easier and more cost effective than putting money in an aging CRT.

I equate CRT's to the muscle cars of the 60's and 70's. IMO there were never any cars built then or now that can compete with them but they are only appreciated by those who know their value and are willing to work on them,everyone else just wants a reliable cheap car.

Once you have had your sets cleaned properly and calibrated, I doubt you'll want to part with them even if something does go bad on them and need to be repaired.

You are obviously an afficianado of the best. CRT has a 20+ year service life. Barco Federal still makes CRT triple gun projectors for the government, for their government-owned flight simulators. I am working on 4 Barco 909's (9" guns) and 3 Barco 812's (12" guns) as we speak, for a retired aerospace guy up in Alameda. Plus a couple more in the wings at his warehouse and his own private 812 in his basement.

CRT is not dead, not by a long shot. Nor does it deserve to be.

Haven't seen one working yet! Am doing repairs on all these guys, with the aerospace guy's help, which makes things a whole lot easier as he is very adept and does his homework thoroughly and very religiously.

Can't wait -
