Super Nintendo not working properly

So yesterday I got a Snes console with one controller, Mario Kart & Mario Allstars. Didn't come with the power adapter so I used my Nes power and started it up but all I got was black screen when I tried Allstars and a white Nintendo logo when I tried Mario Kart.

The cartridges are in great condition, I opened them up and cleaned them anyway. I have also tested them on my other Snes and start up fine every time.

I have also tried with official Snes power adapter the second time around and no luck

I have opened up the console to see any visible damage but since I have no idea what to look for I was hoping someone could point me in the right direction?

 

The NES Power Adapter and SNES Power Adapter are not the same thing. You probably blew a fuse when you used the NES one.

 

PAL NES Power Adapter and PAL SNES Power Adapter are the same thing.

 

Any other suggestions? Today I also tried Mario Paint and Weapon Lord, black screen on both

 

That is good to know (just in case I pickup a SNES in the future)!

Any gunk in the cartridge slot? I once found a massive ball of lint in a Mega Drive I had! How did it get so big! ffended:

 

It sounds like you got bad connection between your consoles protection chip and your cartridges protection chip. Have you tried to clean the SNES connector or replace it with a new one?

 

I have tried cleaning the cartridge slot, ended up using a lint free cloth doused in alcohol and a credit card. I guess I should try it again. The console doesn't appear to be in a bad condition, no massive balls of lint

I wanted to remove the snes connector from the motherboard but was afraid I would stuff something up, might give it another shot or search youtube for a video on how to do it

Thanks for the suggestion guys

 

Had this problem on a SFC with the separate sound module. I thought it was the pin connector so I replaced it and nothing. Bought a spare separate sound module and bam! it worked like a charm. I don't know if Euro models had a separate audio circuit or not though.

 

The connector is real easy to remove as well, it won't mess anything up. You could pull it off and try re-seating it to the main board as well.

 

Thank you ekek2009. I don't think the audio is separate, didn't see a removable sound module. Wasn't sure if the cartridge connector was soldered to the motherboard so I gave up trying to remove it
When I get home from work I will have another go.

 

I don't think there's any removable module in PAL SNES ( except for RF modulator that can be removed, but it soldered to PCB anyway).
Well, if there's a red light when you turn your SNES on and you see changes on the screen, then fuse is intact, if there's no lights - check the fuse first, and replace it if it's fried. If fuse is ok, then try to clean the cartridge slot.

 

I don't know if I was clear enough in the first post, but the power is not the issue here, it turns on every single time.
What I'm not sure is if the cartridge connector can be removed or does it need to be resoldered which I don't think I'm going to attempt

 

Awwww come on! Where's your sense of adventure! :biggrin-new:

 

I'm just not really familiar with PAL SNES board revisions. Some connectors are actually soldered, some aren't. You should be able to give it a good tug and it'll come off. You'd know if you had the separate sound module. It'd look like this:

 

Сartridge connector is soldered. And if you cleaned it and checked for bent contacts without any luck, then you can try to heat connector solder joints, unlike removal it's really easy and don't require some special skills.

 

AFAIK early PAL revisions with separate sound modules are very rare. Bought my first SNES in 92 and no separate module there.

 

maybe the av/rf out is faulty not the cart connector.?

 

It depends on how old the SNES is - the earlier ones used a two-part connector where the base was soldered to the main board and the actual cart connector just plugged onto it. The later ones used a single-part connector that was soldered directly to the board (probably a cost-cutting measure).

Best thing to do is take a photo of the connector and post it.

 

I do have video on Super Mario Kart- white nintendo logo

Sorry about the quality, my phone is quite old
