Is Your iMac Not Powering On?
Logic board failure is one of the most common reasons iMacs refuse to power on. If you’re experiencing any of these symptoms, your logic board likely needs professional attention:
Common Logic Board Failure Symptoms:
- iMac is completely dead with no power, no fan noise, and no LED indicators
- Power button unresponsive, or iMac won’t boot beyond the Apple logo
- Random shutdowns or continuous restart loops without warning
- Blank screen on startup despite hearing the startup chime
- Kernel panics with error messages appearing frequently
- USB ports, Thunderbolt ports, or other connectivity are not functioning
- Graphics distortion, colored lines, artifacts, or screen glitches
- iMac boots but freezes during operation or loading
- Overheating issues with excessive fan noise
- Battery not charging (on iMac models with battery backup)
- No display output despite the iMac appearing to power on
- Strange beeping sounds during startup (POST failure codes)
- WiFi, Bluetooth, or other integrated components are not working
- External displays won’t connect or recognise your iMac
