SNES broken Power connector port issue

Well, I can't recall who asked me about this, or I remember reading something related about it in another thread here.....Nevertheless, I got a freebie SNES system with the common broken power port issue..The chances to find one like it now a days are quite high. Either with a broken port, or found with a non-working power supply (bad transformer, blown diodes.etc..) ..There is no need to let it go to waste even if you are not a Nintendo fan....I figured to post this just in case..

There are a few ways to fix this..For me there are 2, a) The Fancy looking method: which requires more time and effort, and b) The want to play right away and make sure it works (if not known)...I'll explain below:

a) The Fancy method requires removing the rear bezel, where the AV port, RF modulator port and power port are located...Alot of soldering and using more tools such a dremmel involved.

(PIC1-The native SNES broken power port with just a few pins left)

This way is a bit more complicated, because both the RF modulator and old DC port need to be desoldered in order to reach and remove the actual broken port which is built in into the plastic piece.

Once everything is out, solder a standard DC port in the place where the old one was....With a dremmel, exacto knife on anything that can cut plastic for that matter, cut around the old DC port plastic to get completely rid of it and make room for new connector...

PIC2 - Soldered a DC port and the bezel shows a squared spot instead of the round one..

And the most important part, this is where Sega plays a role too.....The Sega Genesis model 1, Sega Master System, TurboGrafx-16 power supply or any DC PSU with center negative and around the same rating can power on this mutt.

And now Method b), Forget about all of the above, drill a single hole and install one of these:

It is a coaxial Power Jack Radio Shack part 274-1582, comes with mounting screw, this and some 20 gauge stranded copper wire will do it too...Simply, wire this jack accordingly to the old broken DC port still attached to the SNES motherboard. and there you go

Sweet I have an SNES I'm fixing up as we speak. Painting it because it was yellow and also the DC jack was broken. Like I've said I've had about 4 SNES pass through me at one time or another with that stupid jack broken. This will come in handy for me really soon!

Question: when looking at the back of the motherboard there are 2 soldering points for the original jack. My original jack is already pulled off. The one point is at the absolute rear and the other in front of it. What one is the Positive?

Great!...A big fan of your videos here by the way :notworthy:

EDIT: @MN12BIRD, the one closest to the edge is positive, the rear one is Negative/Ground

Oh, I forgot to mention!...For those that are having other technical problems with their SNES'es, audio or video problems for example, you see those smd capacitors?..they are most likely dried or drying up, so replace them while you are at it....2x 33uf 25v, 3x 10uf 16v, 1x 47uf 16v, 2.2uf 50v....Some revisions may have more on them

Thanks for this, I have an SNES that flickers color and b/w. Capacitors may fix that.

Dude you totally saved my life... I was looking for a tutorial on this for a week. Searching Google hardcore for hours.

Could you PLEASE do a video on this and post it on youtube? There are hundreds if not thousands of people with this issue looking for a solution on youtube, in other forums, etc. I can even provide you with proof if you don't believe me. Because of people not understanding this issue many SNES'S get tossed out to the garbage. A step by step video could help many people.

Can't you just still use the original SNES power supply with the new dc jack?????

I would love to do this to my SNES, because the power jack plastic cracked. I'll have to do your dc jack repair, but I need a deeper tutorial as I may do something wrong. I don't really know what to solder, and to where because the pictures you posted aren't that clear.

I have intermediate soldering skills but I need an in depth tutorial on how to remove the gray plate, especially how you state you have to desolder the rf thing, and other stuff. PLEASE FOR GOODNESS SAKE shoot a video or create a more in depth tutorial if you don't have a camera.

Here's just one of the people who need their SNES's saved:

http://www.youtube.com/watch?v=I_EAl...eature=related

If you look at the video above it has thousands of views with countless comments of people with the same issue and yet no resolution. You can search Youtube as hard as you want. Please shoot a video... I would even gladly donate some cash for your efforts... There are many forums with this issue, I can prove this to you and show you that no one has helped anyone. A video would help the world once and for all. :)

For goodness sake even look at this thread it has had over 1000 views. For a system with nearly 50 MILLION sold... there is no in depth technical resource out there on this.

Thanks

Generally I have just seen the middle pin broken off (as with laptops...), so I just build another pin for it, less hassle IMO

Well how do you personally do that exactly? Give me a link to a tutorial on that, or explain.

i'll first clean off all the residue of middle pin form the connector, then I get some thick enough strong iron wire, then use zinc-chloride to tin it (iron does not tin at all without it), bend it into shape. Then I get it in place and solder it to the PCB, using lot of solder so it won't get loose form the PCB. It will last forever.

Does anyone know where to buy these gray plates online?

sure, ebay for about $13. For that money you can do any of the above power jack repairs and still afford a beer after all the hassle. Or a pepsi/coke. Or a buck lottery ticket.
