Title: Adjust pots on RF unit?
Post by: sfgsgvs on November 20, 2012, 06:50:21 am
Can you somehow adjust the pots on the RF unit in a Famicom to make it work with a PAL TV? I have a HVC-CPU-07 with two clearly visible pots on the RF unit. Right now I only get a clear b/w picture and no sound.

I would be pretty satisfied if the picture was like now, but with color. And sound of course.

I don't believe adjusting the pots will do any good.

I think the problem is that most TV's don't have NTSC support via RF, even if they have it via AV, so your only options would be to either AV mod your Famicom or obtain a nice CRT with NTSC 3.58 support via RF.

all that RF unit is doing is the placing low frequency video and sound into the proper TV's channel frequency. It can't do any color converting of signal (unless you have a bit wierd HK famicom with ntsc->pal converter)

not sure if you are serious or just trolling us

The TV (new-ish Samsung CRT from 2002-3) can handle an american Jaguar through RF without problem, so NTSC color shouldn't be an issue. But it doesn't like the Famicom for some reason.

hint: your color subcarrier is a bit off.
