One thing I did notice while in there was the dust on everything. Can anyone tell me if there are good, competent instructions on the forum here as far as how this task needs to accomplished. I would like to do it the right way.smile.gif

Thanks for your help in getting her back up and running. My wife sure was happy!!

So glad you prevailed! Now don't be a cowboy in there on your dirty optics - you only get one chance to get it right each time, without permanent damage. Contact me like they say above, and let's get it done right.

Stay tuned, I will also be talking here about my meeting with Paul Darbee and his associates, among them Adam Darbee, who will be my direct contact. After having seen the Darblett in action, you weren't lying! It definitely does stuff that has not been done before.

We are in talks about my becoming a distributor.

Again, they have rules against giving them to consumers, they are only supposed to go to those in the trade. DK why, but that's what they told me when i asked for more. Will be working on getting others for my satellite installations, where i do demos... If I can make you one of those locations, I will.

Michael and Leo and I go way back and we all have live history with each other, so they get all i've got for now...

Send me your snail mail addresses, all 3 of you and I'll get moving on this once I am home again -

Well, I am here again with another Mits 65813 calibrated by Craig Rounds.
My buddy who owns this particular 65813 is getting the 70" Elite in 3-4 weeks.
The TV is located in Chesapeake, VA
The TV was calibrated by Craig in 2007
It has the 2% overscan mod, and the edge enhancement mod that Craig performed on-site.
In 2009, the 9V regulator and DM caps were replaced by Craig during a 2 year tune up visit.
The TV is flawless. No burn-in

As stated, it will be 3-4 weeks, before this TV will be available.
Any one interested?

I can't believe nobody here has pounced on this. I would! If I didn't already have 4 on the property as it is...

There is a discussion on LinkedIn about plasma vs. LCD. When it started 3D was just a glimmer in the eye of its creator. Some new responses just happened, and nobody was taking 3D into consideration.

So I just posted this there, thought I'd share it with you here:


With the advent of 3D coming over us like a tsunami - can you tell I just got back from CES? - the advantage of increased light output to compensate for the essential loss of half your display's light output from keeping one of the images always NOT going to one of your eyes, which is essential for 3D - cannot be overstated.

Many people are let down when they see the reduced light output of 3D even out in the movie theaters, due to one of their eyes always needing to be seeing one of the images but never both. Whether you are using electronic shutter glasses or cross-polarization (RealD 3D, LG Cinema, IMAX and others) plastic lens glasses, the need for one eye to not ever see the same thing the other eye is seeing, stays the same. Result: all else being equal a dimmer picture, with perceived light levels basically cut in half.

Plasma's light output cannot be increased. Neither can CRT, they are both phosphor based. (I am still a diehard CRT fan even so...) In current tech only light driven displays can give us increased light levels. The purity of the blacks suffers, yes, and nothing I know of except OLED can beat CRT for having the best blacks. But since your 3D filters - be they active or passive - are already dimming your light levels down anyway, the blacks in light driven technologies return to their roots and stay pure.

Bulb driven - or LED driven - technology will be best for 3D. When OLED - or its variations like AMOLED and others - gets to being highly available with strong, high brightness organic LEDs being used like they do in the huge stadium displays, that will work too. But right now OLED is still rolling out, for consumers. Until it's more commonplace, for 3D the present light driven modes currently in place will do just fine for making up the difference.

I know very well the virtues of these sets. Putting 9 inch tubes onto a 65 inch screen creates huge advantages.

If i didn't already have one, or even if I lived on the other side of the country, near the set, I'd grab it up.

This model is one of the best CRTs RPTV made.

Would it be forward to say that a cleaned, shimmed and calibrated 65813 or a 73" model with 9" CRTs is the holy grail tv set for those in the know. If I had the means to get that 65813 across the country I'd pounce on it as well.

If the round trip from NJ to VA wouldn't end in divorce, I'd consider it, too.

Guess I'll have to settle for my Hitachi.

Hope you find a good home for it, though.

Too bad it can't be mine.

The other 65813 for sale a year or so ago also involved a round trip from NJ to VA, and he never reported in his post any family problems! Does your wife object to the trip, or another hulking piece of furniture? The 65813 is actually pretty svelte. wink.gif

Yes, MY 65813 was sold to a fellow AVS'er from NJ in December 2011. I think I remember him saying it took 6 hours to make the trip.
He spent 2 hours looking the TV over.
Then, we rolled it right out the front door onto his pickup truck bed.
Last I heard, he was very very pleased. He also got my Lumagen HDQ VP, also calibrated by Craig Rounds.
The current 65813, owned by my best friend, is a beauty. He has been very diligent to prevent burn in.
No Gaming. Non smoking house.
I have had 1 PM about the set.
I will know this weekend if the set is still available.
He mentioned he may GIVE IT AWAY to his nephew.
I am going to let him know that there is at least one person asking for a price, which I also don't know.
I told him to ask $300-400 and see what happens.

I was only able to get $550 for mine WITH the HDQ

One of the bigger problems is that I would then need to get rid of MY baby, which ain't happnin' anytime soon.

I made a youtube video of the problem with my Mits WS-55413 HDTV:

http://www.youtube.com/watch?v=CmiRs7yOF28&feature=youtu.be

TV would not power up for a couple of cold rainy days, then it came back. First time trying to powerup the unit it stops after 4 seconds, second attempt brings it back on and the picture problems appear. After a few minutes it gets better.

Any idea on where the problem is and is it just a board swap? I could do that if it is easily accessible. Our other Mits RP-CRT WS-55315 is just starting to have the same problem, not as bad yet.

Thanks!

Fred

Well folks, I talked to my buddy this morning about selling his Mits WS65813.
His Elite will be here next Friday.
He said he is giving the TV to his nephew for free.
I told him there was a prospective buyer, but he said no, he wanted to do this for his nephew. Very thoughtful on his behalf.
So, I am sorry to get anyone's hopes up, but the Mits 65813 in Chesapeake, VA is not for sale.
His nephew is one lucky 25 year old guy.

Unless you want to pay beaucoup bucks for the Runco 65" RPTV, which actually used one of their full fledged ceiling projectors. That would definitely would be better.

And try a cleaned, calibrated and shimmed 73", like mine!

Other than that, yeah I think we're all in agreement with you on that.

You have a sloppy picture superimposing on an otherwise half decent one. This suggests to me that certain circuits in there are not being kept separate like they should be. They are being co-mingled together, which smacks of coolant leakage on the boards.

The entire Mit HDready lineup was plagued by a huge design flaw on the part of Mitsubishi. They didn't design in overflow bladders on their CRTs like other brands did, and the seals were inadequate to contain the coolant once it warmed up. As a result many many otherwise excellent Mit HDreadys have already bit the dust.

If the coolant hits the left 2 boards when facing from the front of the set, the ones under the red and green CRTs, I have always been able to fix them. They are single layer boards. The right hand one, under the blue gun, not so much. It's a 4 layer board, and once the layers have been penetrated or the coolant has gone under one of the flat pack ICs, it's usually history. So pray to get lucky!

You can send me one or both of the 2 boards on the left for repair when they have had coolant damage. I will do my best with them and get them back to you for reinstallation and testing. Have never failed yet to revive either of them, or both, I have always brought them back alive. You can send me the one on the right as well, but no promises.

Hello all,

I'm newly registered. Have read many of the posts in this excellent thread and have an issue that I thought the great minds like Mr. Bob could help with. I'm not ruling out a paid phone consult either. I purchased this Mitsubishi WS-65869 brand new on 9-11-2002. Have enjoyed and continue to enjoy the picture vs. current panel technology.. Over the last several months, the picture has developed the symptoms shown in the attached screen shots. I have twice returned the set to operation by replacing the 7 caps on the DM module PS board. I just replaced the coolant in the blue gun hoping it was part of the issue since the coolant has never been changed. To my surprise, the 10 year old coolant was nice and clear, and there was no crusty build up on the lens. White text on black screen results in dark band across the screen, which I have seen when editors try to put nice crisp white titles on black background. To prevent the overshoot, most editors put a 1 or 2 pixel blur to soften the light to dark transition..

On another forum, there was a similar problem described which ended up being a bad cap on the CRT PCB. That makes sense to me, but I'd like opinions of those who work with tv circuits on a regular basis. I have a degree in electronics and had amateur radio and FCC first class licenses many moons ago. I went the route of semiconductor fab equipment tech after college that ended up being my decades long career before leaving to start a video production company. Most of my alignment skills are geared towards the camera end of things using wall charts.

I share Mr. Bob's opinion about CRT PQ. I worked for Sony in their booth at NAB and when they brought out their OLED production monitors, they placed two of them next to a CRT in a darkened demo area. It took a few minutes,before I was able to pick out the CRT. That shows just how nice the black levels and contrast can be with OLED. I'm trying to keep the Mits in operation until OLED for the living room comes out of the stratosphere in terms of pricing.

Thanks for any advice you can give me. I know my way around the circuitry but unfortunately, I never invested in a good scope for the house. I was spoiled because I was able to check out nice tools from my employer for personal use on a short term basis. I do have a good Fluke voltmeter though.

Regards,

Greg B.

My recommendation would be to not use a flash when shooting a set with its glarescreen in place, and to correct the spec that says it has 50:1 contrast ratio, which is absolutely dismal. It's more like 100,000:1 minimum, for any CRT RPTV.

You might want to go over your text with a fine tooth comb too. Some errors were pretty apparent.

Just my .02...
