Atari2600a's SNESp

Post by atari2600a » Wed Aug 02, 2006 7:01 pm

My mom's in Egypt for the next 3 weeks, & I didn't grab my Sega Genesis 3 mobo. Just now I realized that I have a couple dead SNES'es lying around! I never looked into the SNES too much to diagnose the problem they all have...

They all seem to have the same problem, they all just plain won't start up! No light, no screen flickering, nothing! (I know it wasn't the Power Supply, because it worked fine on another SNES)

Hopefully, if you guys can help me out on this problem, I'd like to make an MTAC brand SNESp! I'd do it using the same case, by rising the mobo as much as I can & putting a screen & controls on the back!

EDIT: Sorry, forgot to ask the actual question! Does anyone know what the problem is?

More EDIT: For the record, I'd probably also attach a hinge & probably some kind of push-in-clip-lock-thing, for easy maintenance ...

The first mini snes i bought had a repaired power switch. Somebody jumped the one trace with a small wire. I just recently bought another broken snes mini on ebay, and the seller stated that it didnt work unless you switched it on and off a few times. Im guessing the power switch in the minis may be a weak spot.

If you talking about 1st gen SNES, then unfortunatly i dont have any ideas..

Check some of the fuses on the board that are back by the power input. If one of them is blown you can jump that fuse and see if the system can still work. Triton and many others that have worked on SNESs will agree that this is typicly the problem. Just be sure to be careful as if you do anything that would blow a few after you jump it you'll just fry the board and it will be about as useful as a parper weight, so just be careful.

Thanks! (I didn't even know that was a fuse!)

UPDATE: Getting a better SNES from the Attic

Post by atari2600a » Thu Aug 03, 2006 5:40 pm

I dug up one of my SNES's from my closet, & the cosmetic condition of the case is poor! (& I plan to use the case for the SNESp)

Today, when my father gets home, I'll ask him to take the Expedition out of the Garage so I can look in the attic. (The attic ladder pulls down directly above where the truck is...)

For the controller, I'm doing what some of you have done: remove the bottom half of a controller, lay it flat on the portable case, use a pencil to draw where the drill holes are, drill away, & screw the top half of the case & PCB onto the case.

I couldn't find another SNES in the attic, so I'm going to just use something else as a case. For the few of you who have used Tupperware as a case, how good does it feel as a case? I'm not sure, but I might go to Radio Shack today or tommorow (probably not), so I might be able to look at the cases they sell there...

Once I bust my SNES case open, I'll take some pics of the stuff I have.

By the way, is cardboard electrical-taped to a PCB a good insulator?

Its good enough for me, except I use card stock because its thinner.

Okay, the screen I'm using takes 12V... I'm curious, can a 7805 handle 12 volts?

Somebody correct me if I'm wrong, but doesn't the SNES use AC power? It's been so long since I saw a SNES power supply, but I remember it being AC. So...Would this be a problem? (seeing that batteries give off DC)

As you can probably tell from my horrid above paragraph, I know enough electrical lingo to know what all the components are, I just sometimes have a little trouble knowing exactly how they work together sometimes...

The power supply would be AC input DC output.

Are you sure? I remember it saying "Output: 10v AC"...

So, if I find any old 12V AC Adapter (I have buckets full of them), can I test out the SNES mobo w/ one? (The screen can wait...)

It actually outputs 10VDC.

Seriously!? You mean Nintendo fu(n)ked us over by printing AC instead of DC!?

Either way, I am a Nintendo fanboy, & will not object to their ways & teachings. :P
