Oh man, thanks soooo much D-Lite, Who woulda thought changing something as simple as ONE cap,  could go from no sound, TO LOUD SOUND! Thanks so much, you saved me a buncha money (and not on my car insurance!!)

Yikes, I figured the explanation to fix the problem would be "shake the unit" or something an electronic moron could fix.  Looks like I will have to stick to playing my Express with headphones...  this looks like rocket science.

My broken Twin Famicom is also crying :(

I just fixed my new TurboExpress and I just wanted to say that you can substitute the 100uF caps with smaller ones. I used 68uF caps in mine and the sound is nice and loud. :)

So the sound and headphones were not working AT ALL on my Turbo Express and I did this mod - the sound now works in both the headphones and speakers - but its the infamous low sound. Low in both speakers and headphones. What do you recommend doing?

Start looking around the board for capacitors that have broken or corroded legs; check for electrolytic fluid on the board. I'm guessing that you may have another bad capacitor. the 2 big 100's around the sound caps have been bad in the last 4 units I have opened up  ~ but be careful and work very slow ~ The traces love to come up in this area.

100uf 35v caps will work for those right?

and I replace which ones, green or blue: (I already removed one cap in the green and replaced another with the guide)

The area in green. Start there in your search.

The two tiny caps in the green area are 33uf (microfarad) capacitors - Those are the Sound Caps! Replace them first. You can upgrade them to 45uf to "Hot Rod" it for sightly louder volume.

You're getting close.

Correction, 47uf. No problem; Red Ghosts capacitor chart will help too, here's the link:

After staring at it for about 15 minutes, everything should start to make sense.

Actually, all the caps circled in green are in the audio circuit, not just the small ones...

Where is the best place to buy capacitors online? My local radioshack does not have a few of these caps and there is no other local place to shop at.

I got mine in bulk from www.allelectronics.com.  A lot of folks swear by www.digikey.com.  Dunno if that helps or not.
