Title: Help with famicon repair - Damsel in distress!:P
Post by: yanosch on March 18, 2015, 05:20:59 am
Hey guys!

I'm maddie! Good to meet you all! I recently got into old school gaming  and bought myself a broken famicon.
Normally I'm quite handy with electrical stuff.  But this console has me stumped!
I tried it first of course, sadly, no response!
I figured there must be something wrong with the circuit then!

would any of you guys be willing to help me fix this thing? What would be the logical steps to troubleshoot?

I have HVC-CPU-07 model dated 1984

I took some shots for you:)

What PSU are you using ?

PSU has to be 9V with the following :

- negative center,
- positive edge.

Did you check also the continuity of the power jack ?

Welcome to the boards. We have a few very knowledgeable members who I'm sure can lend a hand.

By the way, it's Famicom. ;)

Hey guys! Sorry for the typ-o! Famicom of course!
I'm using an old megadrive PSU! That should be allright right?:)

And sorry for being a noob, but what is the continuity?:)

What other specs would you like too have?

The megadrive PSU is ok.

The continuity is checked with a multimeter :

(starting from the "off" position on the photo, continuity test is the 5th symbol)

Checking the continuity means to know if the signal from your PSU really goes to your famicom. WHen you do check, if the signal is ok you can hear a "bip" from the multimeter, if no, then there's no sound^^.

The famicom power jack seems a bit rusty on photos, so checking continuity will tell you if the famicom is really powered.


We need more info on the problem you're encountering, to help you the best way.
