An iMac that won't power on, boot-loops, or freezes with graphic glitches usually has a board fault — and a board fault is not a death sentence. MacTech Pro repairs the failed component under the microscope instead of selling you a whole new board.

How much does iMac logic board repair in Dubai cost?
Quick Answer
It depends on what actually failed. A blown fuse or a single failed power IC is a far smaller job than deep liquid-damage corrosion or a GPU fault. MacTech Pro runs a free diagnosis first, tells you exactly what failed, and quotes a fixed price before any work begins — typically a fraction of an official board-replacement quote, because we repair the component, not swap the whole board.
MacTech Pro is an iMac logic board repair specialist in Dubai, working at the level most shops in the city simply can't: the individual component. The logic board is the heart of your iMac — the CPU or Apple Silicon SoC, the GPU, the power circuitry, and on the M-series machines even your storage all live on it. When it fails, the official answer is usually a full board replacement at a painful price. Our answer is different: find the failed component, replace it under the microscope, and hand you back your own machine — your data intact — for a fraction of the cost.
We cover every iMac from 2015 to 2026: the Intel 27-inch 5K and 21.5-inch 4K models, the iMac Pro, and the Apple Silicon 24-inch machines on M1, M3, and M4, with the newest M5 covered as it lands. If you've searched iMac repair near me after a dead screen or an endless boot loop, this page is for you. And if liquid was involved, our Mac water damage repair service with ultrasonic board cleaning is the deepest rescue available in Dubai.
Board faults wear many disguises. If your iMac is doing any of the following, bring it to MacTech Pro for a free diagnosis before paying for the wrong repair.
Completely dead at the button. Often a failed power rail on the board — but sometimes just the power supply, which is exactly what our diagnosis separates.
The Apple logo appears, then the machine restarts — or macOS crashes randomly with panic reports. A power-delivery or component fault on the board is a common cause.
Coloured lines, blocks, glitching textures, or hard freezes — classic GPU-side faults on the Intel 5K iMacs, diagnosable down to the chip and its power circuitry.
Fans roaring from cold or temperature sensors vanishing in diagnostics points at a sensor line or SMC-side fault on the board.
Liquid creeping into the base of an iMac corrodes the board quietly. Erratic behaviour weeks after a spill is corrosion at work — and the earlier we clean it, the more survives.
The machine chimes and runs, the screen stays dark. A blown backlight fuse or driver circuit on the board is a small, very fixable repair — not a new display.
Board repair done right is a discipline: prove the fault, trace it, fix the component, test hard. Here's exactly how MacTech Pro does it.
A dead iMac is just as often a failed power supply as a failed board, and the two repairs are priced very differently. MacTech Pro tests the PSU, SSD and RAM separately before blaming the board. You never pay for a board repair when a cheaper part was the real culprit.
The iMac's bonded display is sliced open cleanly with the correct cutting tool in dust-controlled conditions to reach the board — done right, the opening is invisible after reassembly.
Using board schematics, a multimeter and a bench power supply, MacTech Pro traces exactly where the voltage stops. This is how a fault gets pinned to one component — a power IC, a MOSFET, a fuse, a corroded trace — instead of "the board is dead."
The failed component is replaced under a microscope with hot air and precision tools. Most Dubai shops quote a whole new board at this point; we replace a part that often costs a few dirhams.
A board repair never formats your drive. On the Apple Silicon iMacs, where storage is soldered to the board itself, repairing your original board is precisely how your data survives — a board swap would lose it. On badly damaged machines we get your files out safely before deeper work.
The repaired board is reassembled and stress-tested across boot, graphics, thermals and ports before it leaves the bench — and every logic board repair carries a 90-day written warranty.

A note from the bench: on the Apple Silicon iMacs the RAM and storage are part of the board itself, which makes component-level repair even more valuable — fixing your original board is the only route that keeps your data exactly where it is. Older iMacs not listed here are welcome too; if it's an iMac with a board fault, MacTech Pro can almost certainly repair it.
Schematics, a microscope, hot air and micro-soldering — we fix the failed part on your board instead of selling you a whole new one. Most Dubai shops can't do this; we can.
PSU, SSD and RAM are tested before the board takes the blame. You get one fixed number after the free diagnosis, and it doesn't move without your say-so.
Board repair preserves your storage — critical on Apple Silicon iMacs where the SSD lives on the board. On badly hit machines, data recovery comes first.
Ultrasonic board cleaning plus micro-soldering — the deepest liquid-damage rescue in Dubai, for boards other shops have written off.
Replacing one failed IC costs far less than replacing the whole board. That difference goes straight back in your pocket, with no compromise on quality.
Every logic board repair is stress-tested and backed by a 90-day warranty on the work, handed to you in writing when you collect your iMac.
