Original NES will not turn on

[Royalonrawr]

I soldered a blue led into my original NES now it won't turn on. When I push the power button the light will do a single flash for a split second but nothing else. I'm beside myself because everything was working fine before I soldered the LED on. I know it's not the AV adapter because I have three NES and all the other ones work with the same AV adapter. The solder points aren't shorting out on each other either there is no continuity between them. I soldered blue LEDs into my other two NES's and they work great. Any ideas?

Maybe the led is in backwards. Or shorted. Maybe the power switch jumper got knocked loose. 

 

 Did you get it fixed yet?
