iPhone 8 Plus: kept restarting when charging
The client brought in a phone that kept restarting whenever it was plugged in to charge. We found a faulty component on the board, replaced it and tested — the device now works steadily.
Your iPhone 8 Plus won’t turn on after a drop or crash — we’ll restore the board in 1–3 days, no extra charges after approval.

The board is to blame when the phone will not power on, hangs on the logo, restarts alone or ignores the charger despite a healthy battery.
No response to the button or a charger, even though the battery and port have been ruled out.
The phone reboots again and again on the Apple logo and never reaches the home screen.
The body is warm with nothing running and the battery melts away, hinting at a power leak.
The SIM is not found or the camera will not open, which is sometimes a board issue.
The price starts with a board repair and, if a swap is needed, depends on the extent of the fault; the final sum comes after diagnostics.

The final price depends on the fault found and on the repair route you pick.
The technician first checks the power rails and hunts for the faulty stage, then decides whether to repair or replace the board.

Current draw, power rails and data exchange are checked to find the faulty block.

The display, battery and cameras come off before the board is lifted out of the frame.

The board is searched for traces of moisture, oxidized contacts and cracked solder joints.

The faulty block is fixed, or a donor board is fitted when repair no longer makes sense.

Cameras, cables and buttons are moved across and the phone is put back together in order.

Power-on, signal, cameras, charging and sensors are tested to confirm that everything works.
The scope of work is settled once the board has been diagnosed.
Price for my modelA technician usually tries to fix the original board first and considers a swap only when the damage is too extensive.


Boards belong with people who can solder and verify the result, and such work carries a warranty up to 1 year.
The repair comes with a warranty up to 1 year, and the technician confirms the terms before starting.
In 11 years we have seen many board faults after water, drops and botched repairs elsewhere.
Boards and critical blocks are handled by experienced technicians rather than by random hands.
A real cause is found first, and only then comes a repair or swap proposal, with no guessing.
We take devices in two cities, so the matter can be settled wherever it suits you better.
Weekdays 10:00–19:00, weekends and holidays 11:00–18:00, so a Saturday visit is possible.

iPhone 8 Plus Logic Board Repair in Astana with Data Kept Safe
At iServices we repair the iPhone 8 Plus logic board under a microscope, and in most cases the data stays on your phone because we fix the faulty component instead of swapping the whole board. Free 15-minute diagnostics in front of you, board work takes 1–3 days, warranty up to 1 year.
A handset that will not start or runs hot is not automatically a board case. Here is how to tell board-level symptoms from a tired cell, a worn connector or a stuck button.
We rule out the cell, the Lightning connector and the power button first, because those three account for a large share of dead-handset cases and cost far less to fix than board work. A swollen or aged pack, a corroded port packed with lint and a torn power-button flex all produce the same silence on the bench. Our engineer runs free diagnostics in front of you for 15 minutes, reads health, measures current draw and shows you the part that failed. A worn pack can mimic a board fault with random shutdowns and reboots, so a health reading and a current-draw test in the same session separate the two. If the readings confirm a board fault, iPhone 8 Plus logic board repair in Astana starts with the same free diagnostics and a fixed price on the receipt.
Board diagnostics is measurement, not guesswork. Below is exactly what the specialist tests on your iPhone 8 Plus and why a WhatsApp photo already lets us quote the scope of work.
We connect the board to a lab power supply and read its current draw, which tells us whether it is shorted, stuck in a boot loop or simply not getting power. A healthy device pulls a specific curve at boot; a flat line at zero points to a broken power rail, while a spike above the normal range means a short to ground somewhere on the board. From there the technician narrows the fault to a single rail, then to a cluster of SMD components a few millimetres wide. We do board repair under a microscope, so a cracked trace or a cold joint on a BGA chip is visible rather than assumed. A rosin test turns an invisible short into a visible hot spot on the board, so the specialist replaces one component instead of guessing across the whole circuit.
Diagnostics take about 15 minutes and stay free even if you decide not to repair, and an engineer replies on WhatsApp within 5 minutes with a price quoted from a photo of the damage. You sit beside the bench while the specialist opens the phone, reads the current draw and shows you the failed rail on the screen. Before any work starts, the price, the part (original or aftermarket), the turnaround and the warranty are written on the receipt in about two minutes, and the new part is shown in factory packaging before installation. Seeing the test on your own screen and the current reading on the bench removes the "free diagnostics that turns paid on refusal" trap common to aggregator listings.
A technician always has two routes with a dead board: repair the failed component on your own board or fit a donor board. The difference is not only in effort — it decides what your phone carries out of the workshop.
| Option | What stays with you | When it fits |
|---|---|---|
| Component repair | Original board, data, IMEI, paired parts | Single failed controller, codec or modem |
| Full board replacement | Clean donor board, no old data | Damage across layers or unrepairable traces |
| Partial reball | Original board, most data, same IMEI | Cracked solder under one chip only |
A donor board must match the iPhone 8 Plus model exactly and be free of an iCloud activation lock, otherwise the phone will not activate after the swap. We check the donor under the microscope before quoting: board revision, NAND condition, and whether any previous rework left bridges on the traces. The serial number and IMEI are stored on the board itself, so a replacement changes both, and any workshop promising to keep your IMEI on a new board is describing something the hardware does not allow. The honest conversation happens before the screwdriver comes out — if a donor is the only realistic route, you should know that your original identifiers leave with the old board.
The question we hear most before board work is whether photos, chats and the fingerprint will survive. Here is a direct answer, without promises the hardware cannot keep.
Your photos, messages and accounts sit in the encrypted NAND memory soldered to the board, so they survive a component repair and do not move to a new board. That memory chip stores the file system and the keys that unlock it, which is why a technician can read your files from a board that refuses to boot. Encryption ties those keys to the board's own processor, so pulling the chip and dropping it elsewhere rarely works. An iCloud backup remains the cleanest safety net: it copies everything off the device before anyone touches a screwdriver. That is why a dead board can still hold readable information for a specialist, and why a full replacement is the one scenario where your files are genuinely gone unless you had a backup.
On the iPhone 8 Plus the Touch ID sensor and the Home button are paired with the original board, so after a full board swap the button clicks but the fingerprint will not work. The pairing lives in the processor: the sensor's unique key is bound to the chip it shipped with, and no calibration tool lets a different board accept it. We confirm this with you before the work starts, and on a component-level repair the original pairing stays intact because the processor and the button never part. Our engineers test Touch ID together with you at pickup, alongside the other functions on the checklist. A customer who expected a working fingerprint after a cheaper board swap is the most common disappointment in this repair, so we would rather say it upfront than explain it later.
Water and waiting time are the two things owners worry about most. Here is why a board that has seen liquid takes longer to diagnose, and exactly what you get back at the counter.
Once liquid has touched the board, diagnostics can stretch to two days, because corrosion keeps creeping along the contacts long after the phone looks dry. Moisture enters through the SIM tray and the charging port, then settles under the shields; oxides form on the traces and bridge neighbouring lines. We run the board through an ultrasonic bath and inspect every joint under the microscope. Handsets switched on straight away arrive with far more damage than those that stayed off. Powering a wet board on to test it is what turns a cleanable short into burned traces, so keep the device off until an engineer sees it.
A board fault is a specific diagnosis, not a guess, and the right decision depends on what the microscope shows. Here is what matters when you hand the phone over.
Did not find an answer? Message us on WhatsApp: an engineer replies, not a bot.
Ask a questionNot necessarily: a dead battery, a faulty power button or a bad charging port can cause the same symptom. Diagnostics check these first. Only a confirmed board fault leads to board repair.
No, the fingerprint sensor is paired with the original board, so with a different board Touch ID stops working. Repairing your own board keeps it. That is one more reason to fix rather than swap.
Greyed-out Wi-Fi and Bluetooth usually mean a fault in the wireless chip or its solder joints on the board. A drop or overheating can cause it. This is fixed with board-level repair in Astana.
When the speakers, microphones and recording all fail together, the audio chip on the board is often the cause. This fault is common on older iPhone models after drops. The chip or its joints are repaired by soldering.
Sometimes, but the chances fall the longer corrosion works. The board is cleaned in an ultrasonic bath and damaged parts are replaced. The engineer tells you honestly if repair is not possible.
Bring the phone, its passcode and, if possible, the original cable. Know your Apple ID password, because the phone may ask for it after repair. A backup made earlier is also useful.
До этого обращалась в сервис у дома, там только развели руками. Ребёнок поиграл, теперь нет сети. Полёт нормальный
Smotrel otzyvy v 2GIS, vybral po adekvatnosti. Ostavil zaiavku na iPhone 8 Plus. Problema — ne rabotaet zvuk. Vydali nomer zakaza i skazali, kak otslezhivat. Po faktu meniali: kontroller pitaniia. Otdal 15 500 i ne zhaleiu. Posle remonta — kak novoe.

The difference is not always visible, but it can be checked. An original panel is the one the manufacturer installs; an aftermarket copy costs about 35% less.

What “maximum capacity” means, why the phone shuts down in the cold, and how long a new battery lasts.

Power it off, skip the rice, and get the board checked before corrosion starts. Here is the short version of the first 30 minutes.

Most charging faults come from the cable, the port or the battery. Here is how to find the cause and get a free check.
