This is part two in the ever-exciting series:
Losing Sanity: The Art of Soldering.

You can look back at part one here:
CHAPTER ONE: The Failure Of King 9V
===============================================
Ok guys. I did it. My SNES is back on wall current, and guess what?

THE SOUND WORKS.

So, I know nothing's fried. My question is, WHAT NOW?
Its still fully functional! Sound is still alive. But how do i hook up power to a system that hates batteries?!

hmm... when you input the dc voltage, are you inputting it before the bridge rectifier? (like, soldering the input directly to the input traces under the jack)

try using some NiMh or NiCad batteries...if you're using normal alkaline ones, then perhaps they can't output enough current....also, try using enough batteries to get 12v...perhaps your SNES just needs a higher voltage to get sound to work...(the AC adapter outputs 10v, I believe)

AAAH!
I Never Thought Of That!

wow, You're a geinus, Gamelver!
Ill try it now, and get back to you.

Ok guys, Im seriously angry now.
so far:

i had it on wall=SOUND

i had it on 9v=NONE!

i had it on wall, again=SOUND

i had it on 6-D's=NONE! (9v total)

i had it on 8-D's=NONE! (12v total)

WHAT IS THIS?! SOME KIND OF SICK JOKE!?

Somehow, my snes knows its on battery, and in anger, shuts off the sound. What do I do?

hmmmm.....what kind of D batteries are you using?

Sweebez · Post by **Sweebez** » Sun May 08, 2005 7:31 pm

im still using alkaline ones...
dont wanna spend $$$ untill i have some sort of sound coming out...
what else is there?!

Post by **Gamelver** » Sun May 08, 2005 7:54 pm

well, perhaps the alkaline ones can't output enough amps....try getting some NiMh AAs if you can....

The SNES only takes one voltage right? I haven't looked at the back of a SNES in years, but if it does only take one voltage amount, and you still can't get it working, try a universal AC-DC converter.

Yes. You should just bite the bullet and be aware that portables cost money. Certain types of batteries won't be suitable, no matter how big they are. If the system isn't getting the CURRENT it needs, it's not gonna work no matter how much VOLTAGE you give it.
You can try plugging in 2 or 3 9V batteries in parallel just to see if that'll get sound back, but don't run it for very long that way, as it might cause "fun" things to happen... like exploding batteries.
Also, is it possible that your cabling is too thin to get the proper amperage to the system? Even if the batteries can provide it, if the wires can't, you're stuck.

the wires would have to be REALLY small to not allow the current through.....I personally think it's just the alkaline batteries...

no matter how small wires are they will work but if they are too small to carry all the current it will give some resistance heating it up......substancially

i guess ill try the 3 9v idea. If thats not workin, ill just have to get a rechargable one... Any suggestions?

Sweebez · Post by **Sweebez** » Mon May 09, 2005 3:02 pm

OK, It worked, well kinda. I got video...but again, no sound.

I'm not understanding this at all:

How does the fact that its NIMH change the result???
I mean is it more amps? more volts?

Im confused.

What is the heart of the issue, and how do NIMH batteries fix it?

UPDATE!!!!
At the seemingly wise information of (Dave), i hooked up my 7.4v, 800mah Sony Camcorder Battery...You guessed it.

Video, No Sound.

How do you have the whole setup for electricity from a wall source? Maybe when you use a battery, you may have jumped something on the board, or something.
