Super Nintendo not working properly

They're actually pretty clear. Thanks for the pics.

 

OK, it's a 1 Chip unit - so it's almost certainly got the soldered in connector (at least, all the NTSC 1 Chip models I've seen have had soldered in connectors - that's the first PAL one I've ever seen).

It also doesn't have the separate sound module - that was only used in the very early production units and that's a very late one.

 

So pretty much I'm stuffed, will keep it for spare parts

 

Ive bumbed into cart connectors that were too dirty to be cleaned by mere alcohol + lint + credit card. But looking at your pictures, yours look pretty neat, cannot say whats the problem.

 

Can you disable the CIC chip in a 1CHIP? I'd try that to rule out "cart protection" issues.

 

If all else fails, use fire.

Oops, wrong situation.

Get a nice fine sandpaper and expired credit card or used up gift card and try that. Be sure to blow out any dust with compressed air afterward. If it still doesn't work, the problem is not the connector.

 

Dont use sandpaper on cart connectors, it might work short term - but you are breaking it long term.

Emu_kidid - you can disable the CIC on the 1chip without issue.

 

Short term is better than no-term!
It would at least help to know that the cartridge slot is at fault... although if it isn't the cartridge slot... you just destroyed a cartridge slot! :grief:
It's a tough one, that's for sure!

The CIC idea sounds worth a shot though! :smile-new:

 

Just use a multimeter to check the cart slot works - insert a cart and then test from the cart to the solder points of the cart slot, which confirms if there is a connection or not.

 

You are so non-destructive Bad Ad!
Do you channel your destructive powers in a derby on the weekends or something? :wink-new:

 

I have started to see snes's with leaking caps that have ruined the tracks....

 

Don't joke about things like that omp! You'll get me worried... or maybe excited at the thought of more repair work. :cocksure:

 

Thank you all again. So I will check for connectivity like Bad_Ad84 suggested and report back

 

I am pretty sure i have some pics of it somewhere. The tracks dissapeared under a couple of ic's and short of removing them and repairing the traces to maybe repair it...

One of my upcoming projects is to replace the caps in a snes's and my nes. Done most of my sega's lol!

 

Here's hoping something isn't quite right with the cartridge slot! :encouragement:

Hmmm capacitors! I still have those Aiwas to do and all my consoles except the Sophia... this is going to take years! :livid:

 

What would you recommend for very severe cases? Some deoxit products?
I once had a genesis connector so corroded it was green, like old copper plumbing. I used sandpaper to restore them, but then i used progressively finer grit and finished with fine steel wool to give is a polish. I then sprayed compressed air to remove any potential conductive debris and finished the job by spraying contact lubricant to prevent further oxidizing. That worked great, console worked perfect after. If there is a better solution i dont know about it.

 

SNES with leaked caps ? Something like this can happen... in alternate universe.

 

Brasso seems to be good at getting rid of corrosion, which would be gentler on the metal since it's not grinding it off.

 

Ah sir! You got me! I just said that for the giggles! Don't let the truth get in the way of a good yarn.

 

I thought brasso was an abrasive also?
Anyway I only ever used sandpaper twice on connectors, and it was on some damn serious cases. One time was the sega mentioned earlier, other time was on a 486 PC board that suffered battery leakage. I took a photo from the PC board, so I can show you how bad it actually was, and the Genesis was close to that bad.
Believe me or not i actually got cards to work in the slot later on.
