What did I do to my NES??

I don't know if this is the right forum for this, if not I apologize, new here.



Ok so I tried doing the simple mod of bridging pins 3 and 9 with a 47k ohm resistor to get the expansion audio channels for the Japenese Castlevania 3 on my EverDrive. I did one little mistake and accidentally bridged pins 3 and 8 instead. No big deal, I just desoldered and soldered the resistor leg to pin 9 instead. So I figured that was it, I would fire up the NES and have expansion audio for my EverDrive



Nope, this is what ended up happing:







So I don't even know what the heck is wrong with it now and why it shows those weird grey and red lines moving slowing than really fast than repeats. I try to play a game and all I get is a grey screen. The EverDrive had solid screens of different colors everytime I reset the console. I have a brand new 72 pin connector from stoneagegamer.com which worked perfect before I did the mod.



So is the NES that weak of a console that as soon I touch it with a soldering iron it dies? I just got into soldering and my Sega Genesis took so much abuse from me and my RadioShack 75w soldering iron but yet still works! And I eventially got S-Video out of it. I don't understand how an NES dies just like that over some really simple mod.



Oh well, I've decided I'm just going to go the emulator route for the NES using my Wii, just so much more easier and cheaper. So because of that I don't care anymore about having an NES but I'm just curious about what the heck did I break inside the NES, and why did it break so easily?



Anyone know or have any idea what's wrong with it now?

    If you're new to soldering, double and triple check that you didn't short something you shouldn't have. Maybe you used too much solder and it's connecting with another pin or spot on the board.



    You can also take off the resistor, clean up all your solder work and see if the system works.

    Got pics of your work?

    Almost looks like you've shorted Power to Ground somehow, judging from the scrolling lines. Remove the mod you added and see if the issue persists.

    I did remove the mod and it still does that. I also cleaned up the flux I used and used a desoldering pump to take off excess solder. I'm unsure if it still had power in it, you know like when you unplug and then press the power button and the power led lights up for like half a second, I didn't make sure to do that. Could that have contributed to this problem if it still had a little bit of power in it?



    I'll try and get some pics up soon.
