Macbook Pro Retina A1502 dead logic board repair New Zealand

AppleFix New zealand are macbook repair experts in New Zealand in this blog we will demonstrated Macbook Pro Retina A1502 dead logic board repair New Zealand. This Macnook pro showing charging light on magsafe but fan not spinning.

We tested volts on magsafe and getting right voltage and nothing wrong with dc jack it suppling correct voltages. In this case first thing to do is to check the power rails from schematic diagram. Because magsafe charger light is turning on from green to yellow that means adapter sense is working but cpu not turning on so thus gives us idea that cpu vcore line might be faulty.

We checked ppvcc_s0_cpu we checked R7320 where we should get 1.5V but there is no volts on cpu rail. We find short on CPU vcore line. Having short on cpu line means macbook will not turn on.

Next thing to do is to find which part on cpu vcore line is faulty and creating the short? I also recommend not to clean a water damage macbook board before you examine it. Ultrasonic cleaning will wash any evidence which can make repair easier. I find C7374 capacitor little bit of moisture and sticky substance by one side of it. This gave me little bit of indication that this capacitor may be faulty. From schematic diagram i confirm this is same line ppvcc_s0_cpu.

I removed the suspected capacitor and tested with multimeter and short is gone. Got the same capacitor from a donor board soldered it back and macbook wturns on and fixed.
