Alright so I've modded my famicom to use AV and I got the audio working fine, but the video isnt as easy. I tried following this schematic on http://jpx72.detailne.sk/modd_files/fc/avmod.htm but I dont know where to solder the resistors and compasitors. It looks like they solder to the 7805 but I donbt know where to put them exactly or how the video signal would get through then. Im still new to modding. I did try connecting them directly to pin 21 and I got video, but it looks pretty dark. Also I simply put the composite video directly onto pin 21 and I got the same result. so if someone could sent me a pic of this mod or tell me where to solder what.  :'( please help me

I jus tried connecting a a933 transistor to it and now it looks like the fami wont even turn on. I connected the emitter to the 300 resistor the base to pin 21 andthe collector to ground.
