iMac logic boards fail in three patterns: power delivery (no boot, fans only), GPU failure (boots to a black or distorted screen), and T2 or SoC lockup (chime, backlight, but no display handoff). Each has a different fix, and we'll quote your exact fault on WhatsApp.
On 2017-2020 27" Intel iMacs we work at component level - replacing the failed PMIC, MOSFET, capacitor or buck converter on the board itself. That's a 3-5 day job and costs far less than a full board swap. GPU rework on the discrete AMD Radeon Pro chip is also viable in many cases.
On 24" M-series iMacs the situation is harder. The SoC integrates CPU, GPU, RAM and Neural Engine on a single die. If the SoC dies, the board is dead. No micro-soldering can recover it. The realistic fixes are around the SoC: power delivery, ports, T2 secure subsystem on early Intel models. We'll always tell you which side of that line your fault sits on, and refund the diagnostic if a board swap is the only path and you'd rather replace the iMac.

Models & pricing
Every line below includes parts, labour, and a 15-day written warranty. No diagnostic fee, no surprise add-ons.
iMac 27" Intel (2017-2020) - power circuit
3-4 days
iMac 27" Intel (2017-2020) - GPU rework
4-5 days
iMac 27" Intel (2017-2020) - full board
5-7 days
iMac 24" M1 / M3 / M4 - port + power
3-4 days
iMac 24" M-series - SoC fault
5-7 days
iMac Pro 27" (2017) - board work
5-7 days
Component-level rework where SoC and PMIC are healthy. SoC failure on M-series often means a full board swap - we'll tell you upfront.
Common problems
The highest-volume tickets at the workshop. Match the symptom to find the typical fix and price.
PMIC or input-side fault. Common on 2017-2019 27" iMacs after a power surge or PSU failure. Component-level rework - get a free quote for the price.
Boot completes but display handoff fails - usually GPU on Intel 27" iMacs (Radeon Pro 575/580). Reflow rarely lasts; we replace the GPU itself with reballed stock. Get a free quote.
RAM detection failure. On 27" Intel models RAM is user-replaceable from the rear hatch - we test stick-by-stick and reseat. If the RAM controller on the board has failed, board work needed.
iMac chimes, fans run, backlight comes on, then nothing - T2 secure subsystem fault. Specialised JTAG repair - get a free quote for the price. Data preserved.
PD controller or retimer fault. Component-level fix - price depends on which port and which controller chip; get a free quote.
Sensor or SMC fault on Intel iMacs; thermal sensor fault on M-series. Usually a board-level fix, sometimes a reseat. Diagnosed first.
Our process
From the quote form to handover. Each step has a fixed time estimate.
Send the symptoms
Tell us exactly what happens in the quote form - chime, fan, screen. We give a likely cause and a price range before you bring it in.
Bring it in
Walk in to Concord Tower, Dubai Media City, with parking on site - or book a same-day courier yourself and share the tracking link in the WhatsApp chat that opens after you send the quote form.
Diagnosis (24 hours)
Power-rail check, scope on the relevant lines, identify the failed component. Open quote, no work without sign-off.
Component-level rework
Failed chip removed under a microscope, pads cleaned, replacement reballed and placed. IR rework station, controlled thermal profile.
Bench burn-in 48 hr
Stress test under load - CPU, GPU, ports, sensors. Catches intermittents before you collect it.
Collect + warranty card
Ready to collect with a 15-day written warranty and a photo log of the work done.
