iPhone 8 Data Recovery - DC Power Supply Fault Finding

When you know what your DPCS is telling you, you can find faults very quickly and easily. I was able to go straight to the problem with only a quick test of my DCPS and viewing of the amp draw. Quick spikes as shown in this video usually will indicate a shorted power rail. Also, a large steady draw can indicate the same. A small steady draw DOESN'T usually indicate a short, and more commonly indicated a MISSING line, such as a disconnected coil or resistor. A full amp draw BEFORE prompt to boot usually indicates a short main rail. Learning and categorizing what your DCPS tells you is the quickest way to solving board problems, or at least giving you a good hint in the right direction. View this video and others on my channel to learn what your amp draws mean.

This channel is top notch! Keep up the excellent work sir

[@kalisisaac9317]

I am a beginner and I really need to learn what different DCPS amp draws mean. Coz I see when you know what different meter readings mean, it simplifies and the quickens the diagnosis process. Do you have a video about amp draws and their meanings in phone repair please? If you don't have it yet, could you please make us one?

[@iBoardRepair]

You just have to watch all my videos. I don't have one video that combines all of them.

[@damjanovicr1195]

dont ever stop uploading, love the videos

[@iBoardRepair]

I will try to keep them consistent!

[@stevenjudiadan5245]

I love your video

[@iPhoneScreenFix1]

Nice video my friend. Keep up good work cheers from Canada.

[@iBoardRepair]

Appreciate it!

Thamks ❤boss for a good trick.

[@igorborgin54]

Great info, subbed

[@iBoardRepair]

Appreciate that!

[@Nectronixx]

First choice lol, love it when that happens.

[@iBoardRepair]

Yeah always makes me feel lucky!

[@MicroMageRepair]

Very cool, thanks!

[@iBoardRepair]

Thanks for watching! You are always good for a view and I appreciate that!

Can you help me iphone 8 not working

[@TTT-V]

little spike!!

[@damjanovicr1195]

so i had a short on 1v8_io, and when i injected volatage main power melted, camera ic melted, some other ic melted and cpu also melted, i was super confused as to what the problem could be, i followed your instruction i turned the board around, injected the voltage and sure enough one little cap was causing the issue. Line clear now!

[@iBoardRepair]

Make sure you only inject voltage up to what the line is rated for if you are injecting directly into the shorted line. For example, you only want to inject 1.8v on 1v8 line. Good job finding the cap!

[@ristinapharaone2502]

Hi, how many amps do you feel is appropriate when injecting voltage and do you put the black probe on ground?

[@damjanovicr1195]

@@ristinapharaone2502 red probe ground, black probe you test. In my case it was 1v8 Line so I injected 1.8 Volts

[@iBoardRepair]

@@ristinapharaone2502 Black probe goes on ground, yes. In general I keep my amps set to 2 but sometimes my dcps limits it to even less than that.

[@iBoardRepair]

@@damjanovicr1195 Black probes go on ground when injecting voltage. Red probes only go on ground when checking diode mode values.

What DC power supply are you using? Curious if most DCPS measure draw or is that a premium feature?

[@iBoardRepair]

I am using just a very basic, normal dcps. All of them will have voltage and amperage.
