Well I dont use TX Chip - only chips I used front he TX line was the CoolRunner Rev. C and it was a clones lol.. first time ever purchase a chip...
for Slim console I prefer Squirt or X360Run . I dont have nothing again the TX Product gets 2 thing some of them are very expensive.
end 2,, squirt end X360run have less problem to resolve with it come down to it..
I think you console have this problem from the moment you damage those points..
So i recommend you check those point or try a using 30 AWG Kynar Wire
