nes controller not working?

reliant · Post by **reliant** » Fri Jun 01, 2007 8:04 pm

i moved the IC on my nes controller to the other side of the board in an attempt to save space inside the controller, and i accidently broke off one of the pins, i dremeled a lil of the chip off(enough to get to the metal) and soldered it on there, then i soldered the rest of the pins on, and when i try and use the controller, nothing really happens except the screen kinda flashes a little bit when i press a button. did i mess up the chip by dremeling it? or is a connection maybe loose? any help is appreciated.

it's possible that you damaged the IC when using the dremel on it, it's also possible that you just have a bad solder joint, it's also quite possible that you overheated the IC when you were soldering to it.

I would try resoldering all of your connections on the IC and see if that changes anything.

ok i dont think that any of that was wrong, i bought a new controller, and desoldered the IC very carefully and bent the pins very carefully, didnt break any, soldered the chip on the other side and, blah, it still does the same thing, could the problem be my noac? i dont have another to test it, here i'll try and explain what its doing with my mad paint skilzz

Could you have mixed up the P/S and Clock lines? On my NESQuick I moved the 4021 to the other side of the controller PCB (bending the leads 180 degrees) and it works fine.

well i hooked it up many times using the wireing diagram found in the "definative noac pinout" thingy, disconnecting, then looking at the diagram and reconnecting, and still nothing. honestly i believe i may have messed something up on the noac board, because i dont have crappy built in games anymore

. i am probably going to end up just buying another one, only20 bux at the flea market by my house

, but anyway, the only game i can get to play is a cartridge via the family converter. and another quick question, should i have used a heatsink while soldering to prevent heat from going to the 4021? did i maybe damage this one too? no dremel on this one
