[QUOTE="pigoo3, post: 1514300, member: 56379"] You don't. Modern computer logic boards are wayyy too complex...and the individual circuitry is wayyy too small for this sort of troubleshooting. And even if it could be done...there is absolutely no way you could replace whatever transistor, capacitor, or resister was bad. Do you know what this is analogous to?? This is like someone saying that they want to perform brain surgery on someone...but has absolutely no medical training...AND...doesn't even know how to use a scalpel!!! Like I already mentioned...modern computer logic boards are way too complex to diagnose or repair. Your only real option is to purchase a good working replacement logic board. AND in many cases...replacement logic boards are so expensive that it isn't worth it (you could buy the same working computer for about the same money). And yes...I have probably answered this very question hundreds of times...and I have given the same answer/advice!;) - Nick [/QUOTE]
