I always read about how a rejuvenator is one of the best tools to have if one plans to work on monitors. Now I know why.

Prairied1ll0 hung out for a bit last night and brought his rejuvenator. We capped, tested, cleaned and rejuvenated the monitor in my Double Dragon.

And to think I would have settled with the before picture not knowing how badly it needed work. So word of advice, test your monitors and clean/rejuv if necessary. :)
 
that is truly awesome.

I've got a few monitors I need to get capped and rejuvenated. One of these days I will get around to it. But it seems like every time I have money for a cap kit, something else comes up.

That is a sweet picture. Is it the only monitor you did?
 
Yeah this is another "I LOVE THE REJUV" thread....

2.5 hours capped the hareness, fiddled with his jamma harness, rejuv/cleaned the guns in the tube, adjusted the monitor and checked out some Wii gaming stuff.... and we ended at 1:30 am

ONLY ONE MONITOR? 8 hour work day, 4 more hours in a startup meeting then headed to Eseyo1's, 1 hour commute in between...
I was totally burnt out by then.

Money for a cap kit? that's like 6 bucks... isn't that lunch money?

@Mindless Yeah, it was getting late, so we just did the one monitor, but I plan on doing the same to my old 25" K7000 that was in my X-Men. It's nice to have a working spare monitor.

@Prairied1ll0 It was a crazy day for you. Always fun hanging out.
 
Was there any adjustments to the color pots on the neckboard during this process? Don't get me wrong here, the results are stunning...but I wonder how much of the result was due to the cap kit and adjustment versus the rejuv.

I didn't have to do a lot of adjustments to the color pots. When we tested the R, G and B via the rejuvenator, they all read in the red (bottomed out). After doing the cleaning and rejuv, brought them back to life into the green. I'm sure the cap kit helped, but I feel the rejuv is what restored the colors.

I was wondering the same thing. I thought rejuvenation only affected the "strength" of the tube, i.e., how much light it generates (for example, a weak tube is hard to see during the day, while a strong tube is fine during the day, assuming it isn't in direct sunlight). I don't see how rejuvenation could fix screwy colors like that. The "before" picture just looks like an improperly adjusted monitor to me. I know people with TVs that look like that, after they screw with the color adjustments and can't get it back to normal (older TVs, before they had microchip controlled auto and default settings).
 
Hmm...well the red was off for sure before. But I feel the picture is definitely better. Regardless, I think doing both the cap kit and rejuv helped. I'm still new to monitor work so maybe Ken or someone can explain rejuvenation to us noobs. I thought it helped with restoring the tube so that the picture and colors come out more vibrant.

It looked like one of those before and after weight loss/botox commercials. Where the actor is faking the before pic..

The red was way too high, the monitor was too bright, but the tube was missing/had weak green and the rejuv fixed that.. Looks real nice now, thats all that matters..
 
Yes you've got to remember, in the first picture the green is low. However, that could be, because the green gun on the tube is shot. So rejuvenating it definately can make the colors better, not just the strength of the picture. No amount of cranking on the green dial could make it right if the green gun was screwed up.

A rejuvenator cleans the color guns (red, blue, green). The key is to clean the guns and then balance them (balancing is essentially cleaning them to an equal level). Dirty guns can either make a certain color significantly weaker than the others resulting in unbalanced colors that are not ablt to be corrected by the color pots or they can be shorted resulting in one color being shot at full strength, resulting in retrace lines of the shorted color and washing out the other colors entirely.


The process of cleaning is what makes the picture appear "stronger".

I wonder if that is what is wrong with my upper monitor in my Super Punch-Out machine. The reds are dark and can't be adjusted to be any lighter. However, this isn't really throwing any other colors off that I can see.

You can just hook a rejuvenator up to the monitor and look at the guns. The problem you describe could be caused by faults on the monitor chassis as well as the tube itself. The rejuvenator is a quick test to point you in the right direction.
 
Your DD is looking better and better man. :) Really nice outcome! You've got me curious about a rejuvenator as well.

I think you're spot on Bill.

I admit, the first pic, I didn't spend a lot of time adjusting.

The green gun was the one that needed the most work and tested the worst which affirms your point about the green being low.

Thanks for all of the insight guys. I learn something new every day.
 
Looks great! You guys did a great job! I need to do the same for my T2 game it's looking a little dim even with ajustments done.
 
The big point is that we did not adjust the colors after the caps and rejuv.
The guns all test bad and even after cleaning runs on the BK467, they didn't read in the green or yellow reange so I said that I think it needs to be shot w/ the rejuv so we tried one shot at each gun. Afer clean balance cycles, they all read in the low green range so it looked good.

The picture he shows is only with focus, brightness and contrast adjustments.

It was clearly in need of the rejuv. Not sure about the caps, but for 6 bucks and just time... done for good measure.
