How much does iMac Not Turning On - Diagnosis & Repair in Dubai cost?
Quick answer
iMac Not Turning On - Diagnosis & Repair in Dubai starts from AED 400. Typical turnaround: 1-3 days. All repairs include a 90-day written warranty on parts and labour, free pickup and delivery across Dubai mainland, and same-day completion on most common services.
- 90-day written warranty
- No fix, no charge
- Same-day on common repairs
"iMac won't turn on" describes at least eight different faults. Pressing the power button and getting nothing at all is different from getting a chime and a black screen, which is different from getting a fan and no chime. The fix - and the price - depend on which one you have.
The single most common cause on 2017-2020 27" iMacs is a failed power supply. Apple's PSU module in those years uses a high-voltage capacitor that dries out after 5-7 years of Dubai heat. Symptom: dead silent, no LED on the back. Replacement is AED 400 and takes a day. We see it weekly.
The second most common is a startup-disk problem: iMac powers on, chimes, then loops on the Apple logo or shows a folder with a question mark. That's not hardware in most cases - APFS corruption, T2 SSD pairing, or a failed firmware update. AED 350 to recover, often same day.

Fan spins, no chime, black screen
GPU initialisation fault on Intel iMacs, or display handoff fault on M-series. Diagnosed in 1 hour. GPU rework AED 1,500 if Intel; M-series usually needs board work.

iMac Not Turning On - Diagnosis & Repair FAQ
- Older Intel iMacs (2009-2015) have a small diagnostic LED behind the rear vent. One steady light = power supply alive but no boot signal. No light = PSU or input fuse fault. We use this within 30 seconds of the iMac arriving at the bench.
- If it's a power supply, SMC reset, cable reseat or backup battery - yes, same day. Board-level work takes 3 days. We tell you which category your iMac falls into within an hour of arrival.
- Power supply, by a mile. Those PSUs fail at 5-7 years and Dubai heat accelerates it. AED 400 to replace, 1 day turnaround. We have the part in stock.
- No, in almost every case. Power supply, SMC, sensor, port - none of those touch the SSD. Even on logic-board work we keep your original SSD paired to your original board. The only exception is a failed SSD itself, where we attempt data recovery first.
- T2 is Apple's secure subsystem on 2018+ Intel Macs. It encrypts the SSD with a key that lives on the T2 itself. If we replace the logic board, the T2 changes and the SSD becomes unreadable forever. Our process keeps the original board and only repairs the failed component on it.
- No. Free diagnosis, free pickup, free delivery if you decide not to proceed. The only thing we ask is a short WhatsApp confirmation either way.
- Sometimes - backlight failure on 27" Retina shows exactly this. But it can also be GPU initialisation. Free diagnosis tells you which. Backlight repair AED 800, GPU rework AED 1,500.
- Two things: (1) hard reboot - hold the power button for 10 seconds, release, wait 10, press once. (2) SMC reset on Intel iMacs - unplug, wait 15 seconds, plug back in, then press power. Fixes maybe 5% of cases. If those don't work, send it in.
