Question 1

Is it worth repairing an iMac logic board vs replacing the whole machine?

Accepted Answer

Almost always yes for M1 and M3 iMacs, given replacement costs of R 30,000–R 70,000. Even for older Intel iMacs (2017–2020), logic board repair is typically R 3,000–R 7,000 vs R 18,000+ for a comparable new machine. We will give you an honest cost-benefit analysis.

Question 2

My iMac 27" has no display but the fans spin. What is the fault?

Accepted Answer

This is a common presentation for a display controller fault, backlight circuit failure, or disconnected display cable. All are repairable. On Intel iMacs, GPU failure can also cause this — we test systematically to identify the specific cause before quoting.

Question 3

Can you repair the iMac 24" M3 logic board?

Accepted Answer

Yes. The M3 iMac is fully serviceable for surrounding component repair. The M3 chip integrates CPU, GPU, RAM, and Neural Engine — these cannot be replaced at die level — but power management, display controller, USB/Thunderbolt circuits, and board traces are all serviceable.

Question 4

Does iMac logic board repair require removing the display?

Accepted Answer

Yes. iMac repair requires careful removal of the magnetically attached display glass and LCD panel to access the logic board. Our engineers are experienced with this process and use proper tools to avoid display damage during the repair.

Question 5

What iMac faults do you repair most often?

Accepted Answer

The most common iMac logic board faults we see are: no power (PSU or logic board power rail), no display / backlight failure, GPU failure on 27" Intel models, liquid damage (through ventilation slots), and USB/Thunderbolt port failure.
