Thought I would share something I just posted on the ISF Calibrators, where are you located? thread.


"I am going to be in Vegas August 23, at this point leaving again late the 25th. I would be glad to do a calibration or 2 while there and am free to extend my visit if needed.

I specialize in CRT technology - direct view, front projection and rear projection (self-contained CRT RPTV)- and also calibrate flat panels and other projection modalities like DLP (single and triple chip), LCOS, SXRD, D-ILA and Light Valve.

Double stacked CRT projectors are very powerful and deliver some of the finest contrast ratios available, far surpassing the contrast ratios of most of today's backlit and lamp driven devices. See the Screenshot War!!!!!!!! thread for examples.

Screenshot War!!!!!!!!

Only OLED surpasses CRT in contrast ratio, but to date OLED is still in its infancy for production models and AFAIK is limited to flat panels and head visors. Nothing I know of surpasses a CRT double stack in projected contrast ratio. Except of course a CRT triple stack (which yes, has been done!).

Multi-CRT projection (Barco) is used in the Portland OR Planetarium at OMSI (Oregon Museum of Science and Industry). Nothing beats it for showing stars and constellations against crystal clear black night sky. This translates to completely/faithfully captured shadow detail and spaciousness, in home theaters.


I want to see CRT continue to remain in service for what it can do and kept alive indefinitely, rather than simply replaced as a matter of course by profit motivated integrators who want to come in and say "Out with the old and in with the new" and sell their owners all new equipment. CRT tech is like tube audio - it is deep and pure and lasting forever. It shows no signs of letting up on that longevity. And its HD has depth and palpability that many of the fixed pixel devices out there today can only dream of.

My job is to bring out the best in your modality, whichever one it is. Including fine tuning your audio system to silky smooth performance. Audio is half the battle in home theater and should not be left to chance.

My brother has come upon a new way of streaming that is head and shoulders above most of what's out there today, it's called Vstream and has a truly delectable picture. It is one of the few streamers that supports 1080i, but does not seem to have component outputs. As such I am forced to use an HD Fury product with it, to convert the HDMI to component.

I can get a cost deal on these, but have to buy 2 to do so. I would rather just buy a used one, if someone out there has one he wants to get rid of. Or go in with me by buying one for yourself and have your unit be the second of the 2 that I have to buy to get the deal.

I also have 2 Sony bluray players that output 1080i HD on component. Such players are not made anymore, the component OP of today is now capped at 480p. For those of you who have CRT RPTVs that only accept component and were produced before the time of HDMI, these are the last 2 BDPs in the known universe (in my known universe anyway) that will play your Bluray discs in true, scintillating 1080i HD, the highest scanrate our sets can play, with no conversions to 1080p needed (as is true with flat panels on broadcast HD). The HD comes straight from the disc and is sent out in true 1080i while still in the digital domain of the player, the purest form possible for our sets. Needless to say, it's virtually the best way available to see your blurays on any CRT RPTV not equipped with HDMI.

Let me know -

Unhappy 2002 Pioneer SD532HD5 available to a good home

Anyone interested in acquiring a completely functional Pioneer SD532HD5 in the Washington, DC area? We have had the set since 2002, and had the power supply board re-soldered by Bob Jones a couple of years ago. The unit is free to a good home. We are being relocated and have two weeks to get rid of our excess furniture - sorry to say, this unit falls in that category.

Post here if interested.

Let us know if anyone picks it up. I've had one of these sitting in the garage since last year. Put it up on local boards like NextDoor.com but no takers. A few years ago when panels this size were still north of $1000 someone might have picked it up.

Still looking for a used HD Fury II at a good price. I have a I, but the I didn't put out on component, only RGB, which then involved getting an RGB to component transcoder. The II puts out on component or RGB, switchable.

Will be glad to trade that Fury 1 I have for your Fury II plus throw in a few bucks.

I would try a Loftek HDfuryPro. There is a a guy in San Jose that sells them for $35. It looks just like the ViewHD that I have used with my Mits for the past 3 years and it works perfect.

Thanks for the tip, I am only seriously interested in something like this if someone can vouch for it.

So is it the Loftek that you have used, or the View HD? Have you actually used the Loftek or does it simply look like the View HD, which you have used?

Just found it on ebay for that plus tax, just ordered it, shouldn't take long to get here from SJ. Also found the same kind of thing on ebay but without SPDIF output and for 1080p only, which of course will not work on our sets. The Loftek website says this box will do all of them, so it should work just fine.

One question - it says HDCP on it. Will it allow regular movie bluray content thru, or will it block it? If it blocks it, it's kinda worthless. The Fury does not allow any content to be blocked. Even with a fine scaler, the guys with the big expensive projectors need a Fury to get the signal thru intact from their bluray players.

Will let you know how it works -

My unit is a View HD but looks identical. I use it with my Sony Blu Ray player to stream Netflix and other services. I also use it with my DVB-S2 FTA satellite receiver. I don't rent DVD's so I could not honestly say how it works on them.

The unit works fine, but has only been tested on streaming, so I don't know if it will still allow the signal thru on copyrighted material, which is what HDCP and HDMI are all about. This is where the HD Fury products excel, and are needed even when expensive scalers are used, whose signal is still blocked by the HDCP encryption. Using the Fury's as the final stage allows the signal thru intact and beautiful.

" The unit works fine, but has only been tested on streaming"

I thought that was what you wanted it for. Perhaps you should have spent 10 times the cost for the HD Fury.

Image Perfection saves my 710HD !

I have a 15 year old 64" PRO-710HD, and the picture had become so poor that I decided to try to find someone who could clean and tune the set back to its original state. My Internet search found Bob Jones (Image Perfection) who clearly seemed to be the pre-eminent expert on RPTVs. He gave me a list of common products and tools, and on a Saturday morning we spent a couple of hours (on speaker phone) dissembling, cleaning and tuning the set. I cannot describe how incredible the picture now looks!

If you have one of these sets, it is well worth this comparatively minor expense to bring it back to top video form. I would suggest setting aside at least two hours to start, as it is necessary to clean the rear mirror thoroughly (multiple times), and clean all three of the surfaces in each
lens. It is also very important to address readjusting the focal points of each lens, both mechanically at the lens and electronically near the circuit boards. He also quickly addressed adjusting the brightness after properly setting the contrast base, another noticeable improvement.

Bob is patient, and a great teacher. You not only significantly restore your picture quality, but you will become well-versed in understanding how to dissemble the set, the care and handling of various surfaces, and how and why different things affect the picture quality. After a few hours, the picture is now incredibly sharp, text is crisp, color deep. The convergence, a chore that used to require endlessly trying to coordinate moving the color lines horizontally and vertically on the grid pattern with the remote, was spot on without having to deal with that procedure.

My wife came in and looked at the picture and said "Wow!". Even from the kitchen, looking at the set from nearly 25' away, she commented again later at how the picture just jumps out at you. Even walking by the room, from 20' away at a 45 degree angle, I have to stop and admire the picture, even in full daylight. It's a real joy to sit down and watch the TV again!

If you wish to once again enjoy the full quality and capabilities of your RPTV, contact Bob Jones at Image Perfection. If you are a real AV enthusiast, he can take you even further into advanced tuning procedures should you wish to delve into more sophisticated processes. Bob has an incredible amount of knowledge and experience in tuning and caring for RPTVs, and is great at answering all your questions and providing explanations that are easy to understand.

P.S. - I found that having a self-closing, angle-nosed hobby tweezers is a great help in handling the removal and reinsertion of certain screws that are at risk of being dropped into the bottom of the set. Why trust your magnetized screwdriver when you can be more completely confident about handling them!

Vin, my man! Thanks so much for your amazing review! It was fun spending that time with you.

I want to point out that Vin and I performed this minor miracle ENTIRELY ON THE PHONE! I know I have garnered, however unwittingly the rep for saying, "Fly me in!" It's kinda become a trademark for me.

While I love to be flown in and see the country while working, as these sets become sparser and sparser, fewer and fewer calibration tours are being formed. This saddens me, as I always have fun being flown somewhere, but there is hope! Vin was able to pull off this incredible feat while never leaving his home!

There is really no need to fly me in unless you want the full meal deal, the entire enchilada. We filled 4 full hours of me coaching him over the phone on exactly what to do and how to do it, with results to shout about. Scream about! Sure there's more we can do, I have run that down to him, but he wants to kick back and enjoy his superlative pic for a while now. No problem, I like to acclimate myself to things I have just accomplished too, before I move on.

So if you still own one of these legendary sets - did I mention that this thread hit 1 million views last year? Look up the stats - and it's not looking all that fine anymore, spend some time with me on the phone! These sets are just going on and on forever, I no longer say they will last 10 years. Or 20 years. They will last as long as they are taken care of and maintained properly. Do you really want to go out and buy something new that has nowhere near this kind of longevity? KEEP YOUR CRT! It will probably outlast anything you will buy new these days. And with my help you can have a better than new looking set at all times.

I am ready for a phone consultation hour on weekends, evenings and many times when most people would not want to spend time working. It's a fun job for me, and I guaranty it will put a smile on your face.

Call me!

Thanks again, Vin -
