You could try...Powerbookmedic.com

But they may still just want to do "part swaps" (replace bad parts with working parts)...rather than repairing a "bad part". It's just too difficult, time consuming, and expensive to repair & diagnose "bad parts". If there's like on capacitor or resistor that's bad...these are very very (of not impossible) to replace.

p.s. What the heck "new chip" did you use? There usually is no way to replace the "chip" without simply using another logic board. If by "chip" you mean the cpu.
