Interesting Jorge, I bet that is the resin my One PJ has a green tint to it . I can not fix it with out the lumagen, and even then the lumagen has a hard time taming 30 and 40 ire.
it might also explain why i I got better results lowering contrast from the 75 i was running to 72 on that PJ while leaving the other one alone and lowering the ftl by lowering the G2's to match the other PJ.
Ahh the Joys of Blending!

I Think it was a Ground cable that was off touching the board. Look like its just those 2 resistors.

Parts ordered, when waiting i continue with my other convergence board. But i still have a problem with convergence, almost the same as before, i cant move red convergence, just red raster. i can make vertical red convergence its horisontal that wont Work, i located the problem to the controle board, its all working with my old controle board, it looks like its trying to moce green horisontal convergense when douing red, i think the problem came after i touched the green random access, but i have reset the CLM 2 times and reseated the U35 chip on the Board, same same.
Ideas?

Check your HDM cables again. Horizontal convergence of the rasters come from the HDM as well.
Also I wonder if the ground short may have nuked something on your ultra CLM. it may have and the CLMs are different, the ultra CLM has more parts. you can not swap Ultra HDM,s,CLM's, and Back heat sink boards, or Focus boards. they all tie in together.

Hi,
I think that this is only one part of the equation. The complete 'picture' (the complete system and our perception of its result) depends on at least six factors:
- Input signal, its processing and linear amplification
- Electron beam and its intensity at a specific drive setting
- Phosphor sensivity/luminosity
- Optical system including glycol, filtering (C-element) and lens
- Screen properties (reflection capability)
- Human eye properties (sensivity vs. wavelength)
I think the adjustment range for green is mostly due to our higher sensivity for wavelengths around green (~520nm) where even small luminosity steps are noticeable. Maybe Scott has more information on this...
Regards,
barclay66

Guys
Marquee VIMs have limited adjustment range on green gain, I can maybe scope it in the next day or two, it is done on purpose.

Its not working with all non ultra boards to, so no matter what i dit, im sure i did it good.. Damn im not very proud of myself.. Good we dont have high Places or trains close.
There is a buzz from the Vertical board is that normal.?

Sorry to hear that Kurt. I know how it feels to have something working and then messing it up.
Some Vertical boards do buzz, its most likely a capacitor.
Do you have an oscilloscope to check the convergence wave forms?

I have a scope, im not a expert using it, but if someone tell me where to put the probe, i might get Lucky.
Strange thing is that it wont work with any setup ultra or non ultra. There is a 15V RTN i dont get on the motherboard under the vertical deflection moduel.

Just to think positive, i had a positive experience right before the smoke went out. When i was douing the setup, and setting the G2 level with a brightness at 40 i could see scanlines on the tube with low level IRE level, and the lines got much thinner and sharper on screen.
So maybe and just maybe i have done something right somewhere, hope it will happen again soon.
When i think back what happened was after geometry setup, i was making some smaal convergence adjustments on green convergence, after that i went to do the other colors, and noticed that green moved horisontal instead of red.
After some time i found out that i had changed red and green on the convergence board, i put it right, and then it was no longer possible to adjust red.. Then i looked again and the smoke came out when i turned it back on.
What makes me Wonder the most is why.. not even with all the non ultras boards put back in..
I have measured impedance on all coils and look fine, and the smoke went out of the blue chanel, nothing to do with the red green i was working on.

Re check then red channel parts as well just to be sure.
Or you still had the connectors wrong.
Nashou |
The smoke im quite sure was the ground cable not conected touching some component on the blue chanel, nothing to do with the other problem.. just me f*cking up. it shut Down right after it powered on. after i had the rear boards open and closed.
Ill try later change the red to one of the other chanels on the board, get a idea if its the board or coil, or maybe controle board. it just dont make sence. im quite sure its not the convergence board, like both boards behave the same, and both controle boards the same to..

it`s the ceramic capacitors that buzz, nothing odd, mine does this too.

Now its wierd.. Just thanged red and green plug on the board.. wola.. green is moving when adjusting red, so the red chanel output is working the controle board is working, but when i enter green convergence.. well its just working like normal.. with the red and green chanel changed.. WTF.
putting green right, changing blue and red, working like i surposed, then put it all back to normal, and... Ohh now its all working right.. Im confused..

Now stop f*cking with it!!!

The thing is initializating it wont help, just did the same thing to the other controle board, seems like they are both working now.. Its something that gets stuck when changing the colors, but saved it by changing plugs again going true the adjustments with wrong convergence plug in, and then change them back to normal.. wola.. but seems like i have to follow a order.. colors like that.. go true different convergence patterns.. if working now hands off.. hoping to get my parts tomorow get the smoke back into the ultra convergence board.. 2 resistors and 1 transistor what i can find.
Would someone please cross fingers for me.. !!

Thanks.. I just got a bit scared with all my messing up.
I can se they have done a lot of decupling with different caps on the ultra board.. I think it might Work for a much tighter focus.. cant wait to get that one back in.
I did see scan lines on 1080P 60hz before messing it up last night, so maybe my serious grounding of convergence board and neck boards have done more than i emagine.

Could it be that kurt has a P43 phosfor? Those give lower light output at 60 or 72 Hz. Since the projector comes from some simulator it could well be a 3d simulator.
It's just an idea.

Ron. |
Just checked what kind of green tube, its a PT22-19
