510UXB22 Replacements
 

My CRT is just a little too tired I'm afraid as we all know. I've been trying to find a replacement 510UXB22, but I can't seem to find one.

There was an arcade machine at the flea market that used the same CRT, a Pac-Man game, but it had severe burn in (but oddly the CRT seemed strong still).

Is there a compatible replacement? I'd imagine I'd probably have to swap the yokes, but I'd need to make sure I get a CRT with the right deflection angle.

I have a Philips Magnavox in storage that's a 19" and has what I believe is the same CRT picture shape. Low hours too and very VERY bright (which of course I'd run at normal TV brightness, no need to be killing it with contrast).

I don't know what CRT it uses though. It's a late 90's set.

Possible to adapt it? I'll get more information like model and CRT number when I can, but it may not be this weekend. I tried to find a picture of this TV but I couldn't.

Wouldn't be easier to rejuvenate the CRT?

That can be risky, and from what I gather, may not even last long.

Well the CRT is done for anyway, It might be the chance to learn how to do it yourself! :)

Lol

Well right now I can't afford a rejuvenator at this time.

What set is it? The Samsung?
Swapping yokes on a factory converged CRT, seldom works out very well.
Especially, for your application, where the convergence has to be perfect.
Re: A rejuvenator. Most CRT testers, rejuvenators, seldom come with socket required for the later types. :sigh:

Ok. I usually get scared about rejuvenators, but I guess I can give it a try if I come across one.

The CRT still works like it did when I got it, it hasn't gotten worse, but on some color tones, the color bleeds, and I either have to lower contrast more (which it's at a perfect comfortable spot right now), or lower color. CSI Miami and it's yellowish tone is one of the shows that like to bleed a bit.

From what I researched, the socket is a CR25.

Look for a B&K 467, or higher, model number. I've used a 480 for years and have rejuvenated more CRT's with it than I care to remember. Some of them lasted a long time after rejuvenation and some didn't. I was finding weak CRT's in '80's Samsung TV's when they were less than 10 years old; so, I'm not surprised that this one is fading. A Sencore CR70 is another good one.

How many times can you rejuvenate a CRT before it dies completly? Can you tell what brand will respond better to the treatment than others? What are the variable of the equasion? :p

After repairing TV sets for 50+ years, I have a hard time watching a TV, that is slightly less than perfect. Right now, I can't tell you how many sets I have. I can't stand a set with bleeding colors, poor gray-scale.
Some of my old sets aren't as good, but they're not my daily watchers.
The G/W near here had a 27" Sony Wega, from about 2003 for $1.99. It had Super VHS, RGB and all the other options. :drool:

I can't imagine too many times.

An American TV with RGB? That's quite impressive!

Any TV I get with component video, I modify for RGB inputs too as a switchable option. My technique is different depending on how the TV handles those inputs. Most I can just modify the circuitry and get RGB directly fed in. Some need an internal RGB to Y/Pr/Pb conversion if it has one of those stupid all-in-one chips that you can't bypass.

I probably used the wrong terminology. The jacks are Y/Pr/Pb. :scratch2:

Ahh ok. Yea RGB and Y/Pr/Pb, even though result in highly similar color quality (I can't visibly see the difference), are quite different in how color is obtained from it.

I did a bit of clean up in this thread.

Just a reminder that personal attacks are not allowed here, if you don't care for what someone is talking about then move along to the next topic, or use the block function and you won't see them at all.

Thanks Eric!

Agree, thanks Eric. If someone has a problem with me, just send me a PM so it can stay out of public and we can work this out. There's no need to involve everyone else.

Anytime you have to rejuvenate, consider the CRT on the way out. You only have so much cathode material. :no:

This thread will have to be moved to the solid state section, not sure if I can do that myself or not, couldn't see..

But anyway, I borrowed a CRT tester from my old job, it was a B&K, as for the model I don't remember. I hooked it up, and started testing.

Red gun - Very very weak.
Green gun - Very strong.
Blue gun - Meh. It's border lining of good and bad.

So, I went ahead and did what I needed too, and hoped I didn't fry the CRT. After that was done, tested again. Now, all 3 guns appeared to be holding strong. Took several attempts to get this, but it's now holding strong. Red is still not as strong as green though, but all are "in the green" now though so to speak.

Turned on the TV, now all the colors were off again, and so I had to re-calibrated the colors using a colorimeter probe. Got the RGB levels to where it needs to be, and have been sitting down watching the TV every night when I got home from work. I have been holding off posting about this for the past couple days just to be sure it is going to hold, and so far, I tested last night before returning the tester, it's still in great shape now.

And now here's what my picture looks like: http://img.photobucket.com/albums/v3...n/colors-2.jpg

In this picture you wouldn't notice it, but the ceiling light was actually on. That's how bright the picture was, that the TV's bezel looks so dark as if the room light was off. I hadn't adjusted contrast and brightness yet before taking this picture.
Notice how vibrant all the colors are, without a single bit of bleeding or smearing. The color control isn't even cranked up in this picture, I set the color and tint via SMPTE color bars using a blue filter.
The focus on the CRT also seems to have improved which caught me off guard. Because I thought that was a function of the flyback, but it seems the CRT has gained focus too, as you can see in the blue sky, those are the sharpest scanlines I have ever seen on this TV.

For reference, the picture used to look like this, you can see the slight bleeding of colors on the reds.

Lets hope this lasts!

Side note, this old effect: http://img.photobucket.com/albums/v3...n/IMG_0510.jpg

When on a completely black screen in a very dark lit room, is completely gone now. I can be in a darker than dark room with this TV on, on a black screen, and think the TV was off.

The results will only be temporary; but, how temporary is anyone's guess. It could fall off in a week, a month, or you could get over a year out of it. The whole idea behind rejuvenating a CRT is to try and add a little extra life to a tube while the owner makes preparations to either replace the CRT or the TV. Hopefully, this one will last long enough to give you time to track down a reasonably priced replacement. And, yes, low emission can cause poor focus.

I do hope to find a replacement or compatible CRT. Hopefully this lasts long enough till then. I even recently installed new bias multi turn pots.

If you're trying to replace a 90 degree 19" CRT from the 1980's-1990's they're usually interchangeable as long as the number of pins are the same and the neck diameter matches. In arcade monitors the general rule of thumb is use the original yoke that came from the recipient unless, of course the DC resistance of the two yoke windings are the same or really, really close.

In the tv to arcade swap, the tube of choice, 19VJTP22 is hard to find. I usually keep an eye out for early 1990's 19" round corner TVs which I know to have the right number of pins and neck diameter and go through the convergence ritual. There are a lot of 19" TVs around.

Ok, thanks for the recommendation.

I was watching a VHS tape, and even after rejuvenation, I'm seeing this now.

This looks FAR worse than it ever did. But here's the kicker, it's only doing it on this tape, not on cable TV, DTV, or DVD's. I tried the same scene from the DVD, and it did NO smearing whatsoever.

CRT still tests great, doesn't look like it's lost anything so far.

I hope this is just a bad tape.

I think it's a bad tape. If it were the CRT, it would be doing it on every source.

equiv
 

510UXB22 is equiv to 19VJXP22. Common, used in many Sears, Sanyo, Sharp sets.
19VJTP22 will not sub the 510UX.

Hmm, apparently Sears has one brand new.

http://www.searspartsdirect.com/part...&prst=&shdMod=

But it's a 19VJXP22R. But, the price. Wow that's a lot of money for a tube.

$130 for a brand-new (or even well-rebuilt) CRT does not seem high at all. Remember, it is for a TV that cost $350 in 1982 dollars, more or less, and not for a last-gasp $99 CRT set from 2005.

Ahh that's quite true. I keep forgetting the value of this TV back then.

Hmm, new CRT, new flyback, this isn't that bad of a situation actually. It's almost like a new TV (minus the capacitors are still original).

Sadly though since loosing my job I won't be able to afford a new TV, but I am going to keep this bookmarked. Hopefully by the time I get a new job I can afford it.

Wasn't there a thread about the CRTs listed on Sears' website not actually existing in stock?

I really hope not.

I'll be pissed if the website is lying about the stock.

My brother bought that same set several years ago, for his basement rec room. It was something like $188.00, on sale, brand new.
It's an entry level model, as basic as they come.
The thrifts are selling CRT sets, so cheap, around here. Priced at $1.00 to $20.00, on the high end. :scratch2:

I don't know how relevant this is now, but have you tried the procedure I outlined for rejuvenating the CRT? No special stuff needed, use the stuff in your junkbox to do it!
--I posted it here somewhere...

Its a Lot less stressful than the usual booster like a B-K, Muter etc.--ie, no arcing and sparking that just ruins the cathode surface, burning away good and bad material alike....

I/we in the UK recently have been messing round trying some really stuffed CRT's with some good success. The Sony KV1320 I did is still really good...

With all the differences between sets and countries, the CRT low-emission issue is much the same!:D

Just an update, since I had the TV apart today trying to find the cause of whine in the TV for my room mate, I decided to see how the CRT is working.

Put on a movie full of color, turned up the color more on the TV than I normally would.

Still no bleeding of colors. This CRT is holding up quite well.

I think I have one of those CRT's in my repair stock, a Hitachi if I remember correctly. Make me an offer.....

Well as per the latest post, the CRT is still holding up well so far. Still seems green in the shadow areas when warming up, but it DOES wake up now.

However if you live in Florida near the Daytona area I might be willing to work something out.

I'm a bit further east.... New Brunswick Canada (next to Maine). I have a lot of CRT's I'd sell cheap and many I'd give away if anyone wants them.
