Hi,
My wife and I are trying to find someone to mod an Amiga CD32 to output RGB and are looking for suggestions as to who can/will do it.
We am getting ready to buy an Amiga CD32, but our TV is NTSC, and only accepts 60hz signals. So, we are hoping to get around that by modding the CD32 to output RGB instead.
Our Samsung TV’s specs say RGB input, and on the back it says “PC input”, which I am assuming is the RGB.
My understanding is that as far as mods go, this is a pretty easy one, I just don’t know how to solder or read schematics, and don’t want to practice on a classic console.
We have a good history of buying modded consoles and mods of consoles that I provide…
I can provide a list of people I’ve done business with, and also we have an excellent rating on ebay as buyers.
My understanding is that the mod is “just” taking an amiga rgb cable, cutting the db 23, then locate the RGB and video at the TP9 test port near the fmv connector,
where there are pins where you can solder the cable.
Thanks to anyone who can help!
Here is the schematics from the Amiga CD32 FAQ, they aren't showing up right when I copy and paste, so here's the link too:

CD32 RGB signals...
The RGB signals are available from a test port, TP9...

Expansion port Pin 182 `-'
The RGB signals come from the D/A conversion unit and lead directly
to the expansion port. These signals are, however, not amplified. In
addition they are weakened by the S-Video output unit.
As a result I (aim to) insert a 47 Ohm resistor to each colour signal
connection. You may also reduce the load by interrupting the signal
supply to the S-Video unit. Set pin 174 of the expansion port to GND
to achieve that (174 --> u36 (4066) signal switches).
The sync signals connected to the expansion port are unbuffered. As
a result you may re-synchronize your Amiga by an external tact
source. You schould at least buffer the CSync line; there is no
external synchronisation possible on this pin.
Hint: make use of an XOR gate chip. You may negate certain sync
line(s) to adapt your Amiga to (old? :-( ) multiscan-monitors (the
A4000 monitor adapter box will do the same; without the possibility
of selected negation).
