how to ... REMOVE A NECKBOARD???

[italiandoh]

ok, after a lot of trying / filing / fitting i finally found a strongenough piece of plastic. with it, i am able to turn that pot. here's the however: the width of the screen only changes slightly, sometimes the word PRESS at the left side of the screen reads just SS, sometimes it's al least half an R and ESS - but not more. i can turn the pot just by mere fractions but i can also turn it in bigger dimensions - the result stays the same. i can't check perfectly what happens when i turn the knob in varying degrees, because i don't have a large enough transportable mirror here to turn and check at the same time, so it's turning at the back, checking at the front, turning at the back, ... you get the picture.

from what i can tell right now, this isn't working as it is supposed to be . is it possible that the width coil is damaged (as i've stated above, it's wobbly)?

btw, the color problem might indeed just be a matter of color correction on the monitor's neckboard, at least that would be an easy fix!

suggestions?

What is the size of your Paperboy CRT ? I'm afraid the dual frequency Intervideo monitor you are using is for 25" and above sizes. So if your CRT is smaller, you will never make it fit unless you change appropriate components on the monitor. But this would be a total different story, not just a matter of tweaking some pots (or coils). And btw, I never had to touch any coils on Intervideo/Selti monitors, unlike other old monitors as Hantarex 900 / 900E.

without removing the glass and getting an exact measure i roughly get 48 centimeters which equals 19 inch. so basically what you're saying is that the monitor installed does not match the chassis?

Ully, why don't you ask Winni from the german forums? He is a professionally trained TV repair guy with years and years of experience with arcade monitors. He helped a lot of people with their troubles over there...

good idea, sascha! i should contact him as well, but let's also see what happens here

on to the other problem with the colors

i've said that some colors are missing. i've tried adjusting that with the pots on the back, but this is proving to be difficult. let me tell you what i've got:

- 1 pot labeled BLUE DRIVE
- 1 pot labeled RED DRIVE
- 1 pot labeled RED CUT OFF
- 1 pot labeled GREEN CUT OFF
- 1 pot labeled BLUE CUT OFF

first of all i'd like to know the difference between DRIVE and CUT OFF. does DRIVE boost the colors and CUT OFF removes them? why is there no GREEN CUT OFF?

anyway, when i enter the test screens i get screens for each individual color. it starts with RED. so i adjust the pots on the back to get a perfect red. when i then move on to GREEN and / or  BLUE, those colors are totally off (something grey-ish). so i thought i'd better start with the WHITE test screen. set everything up so that i had a bright clear white, moved on to the next test screen which is GREY - still a nice grey. started again with RED, but from what i remember red was green now (or something other than red).

resume: i can get each color i desire, not just all of them at the same time. is there a good method on how to start this adjustment? which color first, cut off or drive, contrast, brightness, whatever?

Ully , ajusting an arcade monitor

I downloaded all these video's and they are on my FTP, so i would say, download them all  

anyway, i remember that you upload a bunch of video's to my FTP, and alot of these where in your upload so you should have them.

I dont know if paperboy has testscreens, in anotherway you should hookup a PC that can output 15khz signals by for example soft15khz software and then run nokia monitor test and see if all your primary colors are correct (R G and B)
(i remember to read something about all green in a previouse post, so the question is , is it the board or is it a monitor problem)
Nokia Monitor Test is a excelent test program, i used it always when i repaired beamers for HP, Coretronics and BenQ

Yes, you will never be able to make it fit horizontally as it is now.

The proper calibration of the video amplifier section of your monitor requires some technical skills and is described on this manual (100 MB) on pages 8 and 9.
However, if you have a fault in one of three the color amplifiers on the neckboard you will never be able to do it anyway. The troubleshooting of this part is described in the pdf "mancirc_en" I've sent you via e-mail, on pages 28 and 29.
Good luck,

Matteo

Yes, I agree with Etienne. Since you are not sure your Paperboy board is outputting correct colors, you should now use another known working source to test your monitor.

If i read all this , it looks like the tube, yoke and chassis are not compatible with eachother in one or another way..

can't you just ditch this monitor and grab another monitor from the shelf ?   

[Superully]

Yes, you will never be able to make it fit horizontally as it is now.

that sucks!!!

i'm afraid that is beyond my skills

paperboy DOES have test screens and the colors were perfect at the start of this (the picture itself wasn't though), then i had the problem with the graphics error, i swapped boards to test another one and since then i have the color issues!

can't you just ditch this monitor and grab another monitor from the shelf ?   

remember: med-res monitor! in fact, i do have a spare med-res monitor here, but it says "APB" on the screen - even when it's turned off . i could try it, but i would have to make some new connectors. btw, i don't even know whether it's working or not!

does the game look real ugly on a standard lowres monitor ?
in that case you probably need to find another chassis....

or does the chassis from the other fit on this tube ?

don't know, but i guess there's a reason why the game needs a med-res monitor - and to be honest, i wouldn't wanna settle with less!

or does the chassis from the other fit on this tube ?

don't know, i'll have to check, but probably not

i could live with the screen being not fitting in horizontally, from what i can tell it doesn't affect the gameplay, but the colors are unbearable. so allow me to ask my question again:

what does (color) CUTOFF and (color) DRIVE exactly do?

You would feed a 24kHz signal into a 15kHz monitor, I doubt that this is a good idea.

Click me  
not exactly a straight answer, but the first link that appears will give some nice info

AH! that makes sence
