Famicon Composite Mod Help

[Beaps]

Hi All,

I tried modding my Jap Famicon tonight & all I am getting is this.



I am sure its the transistor they game me is the wrong one. Any ideas what I am doing wrong or where I can get the correct transistor in the UK?

Thanks

Be sure, that your TV support NTSC(60Hz).

I just tried it my Sony PVM also. Sound plays fine, similar image

Just use the transistor inside your famicom and which guide are you using.

[Beaps]

I removed the original transistor, I'm using the 80sFreak mod

[Pikkon]

Post some pics of your mod so we can see if it's all wired correctly.

Thanks for all your help guys, I really appreciate it!







I took the ground for the video from the other side of the board for now

[Beaps]

Sorry, not quite sure what you mean. You mean what transistor I am using?

[keropi]

^ yep, I take it he wants to know the value of the capacitor and the transistor code you are using

[Beaps]

Sure ok, give me a sec

The transistor is Bc635 fcb, the one from 22 to 21 says 104z, the one that connects to video out is 33

[Pikkon]

Well your using a NPN transistor.I would take out the one your using a use the original PNP transistor and see if that fixes your problem.

[Beaps]

So solder back in the original transistor but life leg E?

[Pikkon]

Yup.

[Beaps]

Oh ok, only solder it to the bottom of the board this time?

[Pikkon]

Yes,its all detailed in this guide.        http://jpx72.detailne.sk/modd_files/fc/avmod.htm
