Trying to hook up Jamma to monitor. $50 for the person to get it going

Hi guys I hope someone can help me and if they can get this going I'm happy to send them $50 for their time as I don't like to muck around and know time is money.
I've been on this problem for over a week now , so don't think it's a easy one to solve.
I have a 48 in 1 jamma games board and trying to connect it to a Sony 27 inch TV- monitor .
This Monitor uses a external box that acts as the tuner and auxiliary inputs, on the rear of the monitor itself it has three input connectors. The first one is Scart , the second is a RGB multi pin plug ( looks like a 34 pin floppy drive connector ) and the third is a composite input RCA..
I have tried hooking up the Scart connection with
red to 15
Green to 11
Blue to 7
GND to 5, 9, 13, 18, 21
Sync to 20
+5 volts through 100ohm resistor to 16
When hooking up on scart only trace line visible and no picture.

Now with the 34 pin RGB multi plug connector here is the pinouts for it :
Pin Description
1 +5V power supply
2 +5V power supply
3 Audio (R) input GND
4 GND
5 Remote control GND
6 Composite video output GND
7 Audio (L) input GND
8 Red Return (GND)
9 Green Return (GND)
10 Blue Return (GND)
11 GND
12 Blanking input Return (GND)
13 H.sync Return (GND)
14 N.C.
15 V.sync Return (GND)
16 GND
17 N.C.
18 N.C.
19 N.C.
20 Audio (R) Input
21 Mode Select
22 N.C.
23 Composite Video Output
24 Audio (L) Input
25 Red Input
26 Green Input
27 Blue input
28 N.C.
29 Blanking Input
30 H.sync or composite sync
31 V.sync
32 N.C.
33 RGB/NORMAL mode select
34 Audio Select

Now with this plug I couldn't find the right way for the female connector to go in as the web page does not show where the key should be on the plug .
http://pinouts.ru/Home/sonyrgbmulti_pinout.shtml
I checked the voltages for the two +5 volts feed as shown in the diagram and found two feeds that were 6.45 AC so I take it that's Number 1 and 2.
Than I tried to hookup the wires as shown now.
8 to GND.
9 to GND.
10 GND.
12 to GND.
16 to GND.
25 to Jamma red.
26 to Jamma Green.
27 to Jamma Blue.
30 to H.sync Jamma
Only trace line showed ( no picture )
Now I also found that number 21 of multi pin is a mode switch that switches from Digital RGB to Analogue RGB. I tried to put a 100kohm resistor from 21 to ground then 21 to +5 volts , then I removed the resistor and gave pin 21 a direct Neg and then +5 volts ( no such luck picture still the same ).
I also found that number 33 is RGB VS Normal and did the exact same as above with resistor and direct Neg and +5 volts to which still nothing appears on screen.
If I hook up my Computer monitor to the VGA output plug on the Jamma board a picture comes up Ok but I have to set the Dip switch to VGA mode. With all my testing I did try both settings CGA and VGA.
Now with the composite monitor input I hooked up a DVD player to it and picture appears ok on the monitor so I know that side works.
So you see I just about tried everything I could think of and my last way out would be to buy a RGB to NTSC/PAL converter so I can run the game from Jamma to Composite RCA but I know I will be loosing quality so that's my last resort.
Help to get the Scart or RGB multi pin going would be greatly appreciated. Thank you and regards Electroman2006

Have you tried connecting pin 8 of the SCART to +5v?

Thanks for the that Barakka but I did do it and nothing happens ( forgot to put that down on the original post as I also put it through a 100ohm resistor to try ).
Now I think I found the problem . Last night I was up until 4 am trying to figure it out and tiredness started to come into effect. I said to myself stuff this I'm pulling out the monitors rear circuit board and checking the Scart and Multi pin connections on the board. Well Surprise surprise , with the multi pin outs on the circuit board was labeled with the pin numbers and NO WAY looked like the ones I got off the net ( AARGGGGHHHHH) The ones from the net read 1 up, 2 down, 3 up, 4 down and so on and on the circuit board it reads from left to right 1,2,3,4 and so on.
This is break I was after , I lesson learnt NEVER trust the net. I'll post more soon regarding if it worked. Regards Electroman

Well success at last , Picture comes up but two small issues I now have to deal with .
First is that the image isn't 100% , I don't know if it's the fault of the 48 in 1 games board or my monitor . All images produced on screen has small lines going through them ( game playable but reminds me of the old Atrai graphics) As I don't have another Jamma board I can't really test to see if it's the fault of the multi games board .
Secondly the image shown on the monitor comes up horizontal and after spending many nights after work making the brackets to hold the screen in place it's going to be a real pain to turn it around and make new brackets ( Would there be a better solution to fix this ? ) Oh well not major problems but more teething ones at that.
Here is the wiring diagram of how I connected up the RGB Multi Pin plug.
1 bridged with 33
2 bridged with 29
GND pins bridged 4, 8, 9, 10, 11, 12, 13, 16,
25 to Jamma RED
26 to Jamma Green
27 to Jamma Blue
30 to Jamma Sync.

will this even suport your jamma video?

Hi , yes it will support my Jamma Video but there goes my plan on watching DVDs on it as well . I'm making new brackets to turn the screen around to view Jamma and by using the normal RCA video input connection on the rear any input on this can only be viewed by tilting your head on an angle. Win some Loose some I say.
