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.

macbook air a1466 backlight fuse and lcd connectors repair hamilton new zealand

Professional macbook repair in hamilton new zealand. This macbook air a1466 baclight fuse and lcd connectors repait done at applefix hamilton. The logic board of the macbook was liquid damaged and after some repair attempts at other macbook repair shops it was sent to us. Full backlight circuit was blown including lcd connectors. i have already wrote a blog on macbook backlight ic repair which you can read here.

On this macbook first we tested backlight ic whcih was faluty and it was replaced but even after replacing the back light ic still no image. i checked the lcd lvds connectors and find that both backlight lines are burnt on lcd connectors and one of the backlight line pad is ripped / burnt.

Even-though i could have jump wired burnt connectors to existing lcd connectors but because of the extreme liquid damage i decided to replace the macbook air lcd connectors.

In this kind of repair it is very important to have knowledge of how to read schematic diagram. Specially when some of the pads are burnt on pcb board. Without not having the knowledge of where these lines are leading to it is almost impossible to do a successful repair.

If you are reading this article to have some knowledge it is important to know that water or liquid damage electronics will not work just by cleaning because if there is a short on the board it cant be removed by cleaning. Cleaning is important but after you finished examining the board. The solution we use for ultrasonic clean are military grade and will will leave any traces of liquid damage after cleaning and it will be hard to find damaged area. For example see in the below picture we can see where the damage on the logic board is.

If your macbook or any other electronic is liquid damaged. Do not turn on do not charge you will make it worse. Rice remedy and hot cupboard treatment never worked. Having moisture or any liquid inside or on the logicboard will create conductivity and flow of the current throu this conductivity will burn the small components on logic board.
