In this video i have shown iphone dead repair, how to find faulty component or short on iphone logic board Not just one but there were multiple problems on this iphone. There are several ways to find the faulty or shorted component on the iphone logic borad. But before i go into details of how to find a short on the logic board or any logic board it is important to know what a “short” means in electronics.

 

A short circuit on PCB board refers to a condition in which electricity strays outside the established pathway of an electrical circuit. A short circuit happens when electrical flow completes its circuit journey via a shorter distance than is present in the established. On iphones there are two types of short ” in put short” and ” output short”. In most cases if the iphone is not liquid damaged usually it is a burnt capacitor that can create short on the iphone.

 

How to find shorted component on iphone logic board.

There are different ways you can find a shorted component on iphone logic board. The most commonly used method is supplying power to logic board with external power supply and check or feel with your hands where the log board is heating. With this method it is pretty hard to determine exactly which component is heating because there are components which you can see clearly on under microscope.

 

Isopropyl alcohol is easily available solution and can help to find which component  is heating. You can also use freeze spray which is shown in the video.

 

If both of above methods fail to conclude or find the faulty module or part. Thermal camera is best solution as shown in the video.. Watch the below video to learn how to uses, isopropyle, freeze or thermal camera method to find short on PCB board

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.

If your macbook is dead and you have been told it is not fixable it is worth trying with us. We also offer logic board repair courses.
