They are a pretty darn close matchup to eachother.   Go for it !!

OK i have a similar thingy after cleaning up my cabinet and putting the wrong plugs into each other 
A had no blue color, just green & red ...
Switched RGB pin an the jamma plug (soldered), so my blue does work!
So i take a look on the scheme, the good thing is that the 3 colors circuits are identical so you can compare to each other!
Take a look at the electronic board at the back on the tube, swapped the rgb's like i did on the jamma plus and the colors are all working just one missing wile swapping.
Built out my chassis measured all components of that circuit, i had a broken zenerdiode!
Changed also capacitors & transistors as i was afraid of damage after connecting the wrong plug .....
And it works! Lucky me 
Oh i have a hantarex mct9110 monitor, but i presume it's much the same ....

Hi guys,

I'm sorry for the lack off updates on this but i have been very, very busy. 

It's been 3 months since I've came here with my monitor problem, and i finally got it to work with the help of all of you. 

Hopefully i will get some screenshoots once i finish installing the software.
In the meantime, here is a pic of the neck card with the new chip installed. 

Cheers,
Mac

thats good news,was the problem the Lm decoder i/c in the end or other

[MacStone]

Yes, it was the IC chip.
I've managed to solder a socket onto the board, to facilitate the chip's removal.   
Now i keep one spare just in case.

[grantspain]

well congratulations and it looks a pretty professional job as well,sockets are always handy.now we just wait to see perfect screen shots

Hi guys,
Where can I purchase  these transistors for the neck board, and capacitors?

Thanks
