Sega master Sytem II replace RF for a 8pin DIN

hi there,can anyone help me?there is any tutorial or anyone have de shematics so i can replace the rf unit and put a 8pin socket in a master system II.like in this video:

 

You could get a French Master System II. It already has the din socket.

 

Here's the service manual for Master System II

http://gamesx.com/wiki/lib/exe/fetc...aster_system_ii_service_manual_april_1991.pdf

It should have all the info u need. I think it only outputs Composite Video and Mono audio. Good luck.

Edit:

Just found this guide on getting full RGB direct from mobo

tks for the tips but i like to mod mine own console.i gonna check the service manual.tks for all!

 

tks.i like to leave the result of the mods:
Led bi color on the on/off button and revest because of the bright led ligth,and to add some final look to the button

Console whit switchless mod 50/60hrtz

Goodbye RF..welcome RGB



Pause button


Control pad printed on a 3D printer



There's a video of the final product

 

Very nice. Skilfully done. Liking the dual led mod.

Did u perform the RGB mod as well or is it still Composite video?

 

Taijigamer2 tks!
its a rbg mod.i made the cable so its composite Video but i already order some LM1881 so i can make it composite sync

 

Very nice. Have u thought about writing this up as a tutorial.

U could try wiring SYNC_O (pin11) of the CXA1145P to give u pure sync which would negate the need of a sync stripper. Not sure if the signal is strong enough which is why other tuts say to use Sync over composite but may be worth a go.

 

Master System 1 has separate pins for composite video and composite sync. If you copied its layout by following the service manual, either type of cable should work in most situations. Unless a TV really needs one or the other.

 

@Taijigamer2 i can make a tutorial
i use pin 11 from the CXA1145P,but what its the pin to use in the scart?PIN 20 ou 19?i use pin 20 for composite video.do i need to replace just the wire of PIN 20?replace composite for SYNC_O?tks for all.i gonna need to make some test's....and new wiring to the tutorial,because this its a test wiring.i gonna leave some pic of my SNES whit Super Pic.please tell me what you think about the wiring:

 

That sounds right. Modding a PAL SNES to resemble the NTSC SNES, means you've replaced the +12V output at the rear multi-av with csync. But I've never used a European TV with SCART switching to say for sure how useful the +12V is.

 

@Lum ??????sorry.????iam talking about master system,i only post that images of SNES so you can tell me if my wiring work its good or not!but tks anyway

 

In answer to you question about sync. Pin 20 is for composite video OR sync.



If u are running a pure sync signal to pin 20, u will need to apply 1-3v on pin 16 to switch the TVs to RGB mode otherwise u will get a blank picture as it will be looking for composite video on pin 20.

Pin 19 is for video out which is only relevant for DVD players and other devices which have SCART sockets for output.

 

@Taijigamer2 sorry to ask but here i gonna get that voltage?do have any schematic of that?tks for all!

 

I use this page for all my RGB cable info

Just wire 5v to u'r RGB connector on the mobo side and then put the relevant resistor between pin 8 and 16 on your SCART connector.

 

Taijigamer2 ok.that its the same schematics i use to make my cables.i gonna try replace just the wire on pin 20
