4-years old MacBook Pro's logic board failed!

[pigoo3]

The guys at the Apple shop didn't go any further than saying the logic board failed!
Do you know/think the diagnostic can go up to the detail of finding the local fault?

They don't need to go any further. Because Apple isn't going to repair an individual solder joint on a logic board (if that is the problem)…or replace an individual resistor, transistor, capacitor or IC chip, etc. If something is wrong on the logic board…then Apple replaces the whole logic board. Logic boards are VERY VERY complicated things. And to find & repair an individual solder joint is not easy.

Even if logic board repair was possible…the reason why it's not done is "dollars & cents". The cost to repair a logic board (even if it could be done) would be pretty darn high. The hourly labor rate for repair technicians isn't cheap (even auto repair dealerships charge $125/hour and higher for labor). And fixing a logic board also requires some very expensive & complex equipment. So the cost of this expensive equipment has to be taken into consideration at well.

So let's say to costs $300 to fix a $500 logic board (or maybe more). It's just not a financially smart thing to do (when these same employee's can be doing other much more profitable activities). Especially if a "failing" logic board may all of a sudden develop a 2nd, 3rd, or 4th problem after the first problem is repaired. Now we could be talking $300 + $300 + $300…etc. etc. to repair things.

This may still be useful to you. In February 2015, Apple admitted there was a problem with the graphics card on some MBP between 2011-13.

Mine failed again in September this year; logic board (third in four years) replaced FOC; 10 days later failed again. Apple have now replaced my 2011 MBP with a NEW 15" MCP Retina (plus SperDrive), completely free of charge!!
