iMac 27-inch Repair FAQs
How much does iMac 27-inch repair cost?
Every iMac 27-inch repair begins with a free, no-obligation Quick Quote. You get an upfront fixed price before any work starts, and our no-fix-no-fee promise means you only pay if we solve it. All repairs carry a 90-day warranty.
Can you recover data from a iMac 27-inch?
Yes. We can recover documents, photos and files from your iMac 27-inch’s SSD, NVMe or hard drive — even if it won’t boot or power on. Ask us to image the drive before any repair so your data is protected.
Do you repair the iMac 27-inch out of warranty?
Absolutely. We’re an independent repairer, so we fix iMac 27-inch units that are out of warranty or no longer supported by the manufacturer — usually faster and for less.
Where can you repair my iMac 27-inch?
Australia-wide. We offer onsite visits, secure remote support, and workshop repair with nationwide pickup — whichever is fastest for you. Call 1300 723 628 to arrange.
Why won’t my iMac 27-inch turn on?
A iMac 27-inch that won’t power on is most often a failed power supply or adapter, a power-button or front-panel fault, or a motherboard issue. We diagnose it for free, give you a fixed-price quote, and most no-power faults are repairable — no fix, no fee.
My iMac 27-inch screen is black, dim or cracked — can you fix it?
Yes — on an all-in-one the screen is built in, so display, backlight and panel faults need careful repair. We diagnose whether it’s the panel, the backlight, the graphics or a cable, then repair or replace it.

iMac 27-inch Repair — your questions answered
How much does iMac 27-inch repair cost?
Pricing depends on the exact fault. A power supply board swap starts around $280 while a logic board replacement can reach $780. Every job receives a fixed quote after diagnostics so you know the total before any work begins.
Can you recover data from a failed iMac 27-inch hard drive?
Yes. Our technicians image the drive in a clean environment using professional tools before any replacement. Recovered files are returned on an external drive or uploaded to secure cloud storage.
Do you repair 27-inch iMacs with vertical lines or graphics issues?
We do. On 2011-2013 models the common cause is degraded GPU solder joints. We can reflow the board or fit a tested replacement, then reapply fresh thermal paste and test under load.
Will my iMac 27-inch still be supported after an SSD upgrade?
macOS updates continue regardless of storage changes. We fit a compatible SATA SSD with the correct thermal sensor adapter so fans remain quiet and the machine runs the latest macOS version supported by its model year.
How long does an iMac 27-inch power supply repair take?
Most power supply replacements are completed the same or next business day once parts arrive. Onsite visits are scheduled within 24-48 hours in capital cities and major regional centres.
