[MAHO800C_2011]

I am a new member and have a question regarding the RGB horizontal+ vertical signal on a Maho 800C( manufacturing year. 90) – screen.

After switching the screen on, the picture on the CRT display is very blurred- only after around 1 / 2 hours the picture becomes more legible.

When talking to Maho, they said that maybe the power supply unit might conk out soon.
Now my question ( as a non electrician):

We got a converter card from CGA to VGA ( to connect normal TFTs). With this card there is a connection cable, which is reserved with 6 cables.

We should now connect the signal of the Maho with this cable.

R G N horizontal vertical and mass.

However the 15-pole SUB-S plug of the Maho has

Blue, white, yellow, green, rose, brown and mass (so 7 cables)

Can anybody tell me what cable has which signal?

Many thanks for all your answers!!

Hello
I have found the page of the circuit diagram.
Unfortunately, only the colors are described. Is there a RGB VH allocation for them?
