SNES won't power on... chance for recovery?

Former Member

Hi everyone,

 

I posted this in /r/SNES and got no useful help, so I figured I'd come here because I'm assuming people in this forum know at least a little more about electronics...

 

Anyways, I bought two SNES units for the low low price of $20. One of them worked mostly fine while the other wouldn't read carts at all (fixed later with some good ol' isopropyl alcohol). I was cleaning them both up just to get them in as best condition as I could, and in my process I decided to clean the cart slot of the mostly working unit. I had the board out of the case at this point, and after I cleaned it I wanted to test that it still worked. So I went over to my TV, plopped the SNES down on my carpeted floor (I think this was my mistake), plugged in the power and POP! I saw a spark form the board towards the back where the power is. I attempted switching the unit on and nothing happened; no power LED, no video out, nothing. The fuse isn't blown (I think - I did a rudimentary continuity test my using the power button leads on my computer motherboard and the PC turned on when I contacted either side of the fuse with some cables), so I'm assuming something in the power delivery mechanism got fried.

 

How can I diagnose exactly what's wrong with my SNES, and would I be able to fix it? Thanks in advance for any responses!

 

Edit: Just to clarify, I did use the official power supply, so I don't think it was that. I'm guessing there was a short somewhere else on the board besides the fuse. Also, I attached pictures of the board.

    Do you see any obvious signs of burning on any board components?

     

    Can you remove the fuse and do continuity test on it?

    I did a cursory look at it after the incident, but couldn't see anything obvious. There was that "burnt electronics" smell, but there were no visible signs (to me) that anything happened. I don't have the board with me at the moment but I can check later to be sure, or maybe send pictures.

     

    I might be able to remove the fuse and test it, is what I did initially (with the PC mobo) a solid way to test continuity, or do I need a multimeter? (I'm a real electronics noob and don't have one. Might be worth the investment...)
