Gets 5V, won't step up to 20V — charging stuck in a loop.
At first glance the power IC looks guilty.
Tracing the supply chain backwards, the issue was an upstream enable line.
Follow the chain, not the part.
Not part-swapping guesswork — see the system, find the fault. From holding a multimeter to board-level diagnosis, step by step. Start your 14-day free trial. No card required.

Phase 1 — 14 days — on us. Aside from the signup form, no payment, no credit card. Across 8 phases you'll build the bench reflexes — from measurement to processor, from signal to logic board. Start today, read boards by day 14.
“When I finished the power-sequence lesson in Phase 2, I read the PPVBUS_CONN line correctly for the first time.”
Occasional emails about new phases, certificate prep, and free resources. No spam, no card.
If you want to learn electronics repair, let me tell you one clear thing:
The problem isn't the devices — it's not understanding the systems.
Sound familiar? You're not alone.
Most training says "this point should read this voltage." But why the voltage is there, how far the current spreads if it's missing, which block feeds which — that's never shown. Memorization works on one device; the moment the fault changes, you're stuck.
The invisible cost of continuing without training:
My curiosity started in 2005 in Azerbaijan. Military service, two countries, Antalya in 2018. Both sides of the bench stayed the same — device, screwdriver, microscope, oscilloscope, solder, patience.
In Antalya I founded Elma Teknik Servis. MacBooks, iPhones and iPads arrive by cargo from all over Türkiye. Every device a case, every case a lesson.
“I built this academy so the system I learned over 20 years wouldn't sit in a shelf full of folders.”
From safety to measurement, processor systems, communication layers, peripherals to RF, from board literacy to controlled intervention — an 8-phase engineering arc. Phase 1 is live — new days ship weekly.
Academy lessons aren't one-way like a technical book. Learning objective, concept, measurement flow, İlham's bench notes, quiz and live RAG case — 11 layers woven into the same day.
What you'll understand by the end of the day
Each layer is shown to the student in sequence on the same day. The difference from one-way video courses is right here — every concept is processed from 11 different angles.
Representative cases — full diagnostic steps and measurements are inside the academy.

Tracing the supply chain backwards, the issue was an upstream enable line.
Follow the chain, not the part.
Cable plugged in, draws no amps; occasionally heats up.
The first instinct is to replace the charge port.
A short on the charge line was also pulling down the data line — the port was fine.
The symptom is in one place, the cause may be elsewhere.
Powers on, fan spins, but the screen is black; no external display either.
Assumed to be the panel or display cable.
Not the backlight; a power rail was missing — the board produced no image at all.
Don't replace parts before measuring.
Screen is intact but touch won't register, occasional ghost touches.
The first thought is a digitizer/screen swap.
There was noise on the touch controller's supply line — the screen was fine.
Question the signal first, the part second.
Battery at 0%, adapter connected but no charge; SMC reset doesn't help.
Assumed the battery or charge board needs replacing.
A MOSFET on the charge-control line was shorted.
The symptom says 'battery,' the cause may be in power control.
Horizontal lines on screen, occasional white-out.
Assumed a panel fault, screen gets replaced.
Not the screen; the display supply rail had low voltage.
If a new part shows the same fault, check the supply.

The workshop's apprentices — opens in Phase 6.
Two separate programs, two separate specializations. The electronics core teaches the systems mindset of processor-level repair. The board-level repair program carries that mindset onto iPhone, iPad and MacBook logic boards — three devices in one package. Whichever you buy, all of its phases open up.
One correct diagnosis is sometimes worth more than the price of the course.
