iMac Logic Board Replacement in London | Certified Apple Experts – Macguys

Your iMac often does more than just sit on your desk; it's the quiet powerhouse behind your creative projects, your workday, and your personal productivity. So when it suddenly refuses to start or shuts down mid-task, it can feel like your entire setup has come to a standstill.

Instead of buying a brand-new machine, you can rely on Macguys, London’s trusted team of Apple repair specialists, for professional and reliable iMac logic board repair and replacement services. Our certified Apple technicians use genuine components, advanced diagnostics, and careful workmanship to bring your iMac back to full health quickly, safely, and affordably.

Why Logic Board Replacement Matters

The logic board, often referred to as the iMac’s motherboard, is the central hub that connects all your computer’s vital systems from the CPU and GPU to memory, ports, and power management. If it fails, your iMac can stop responding entirely.

Signs Your Logic Board May Need Replacement

• iMac not turning on at all
• Sudden restarts or freezing mid-use
• Black screen even when powered
• Burning smell or visible internal damage
• USB ports, Wi-Fi, or Bluetooth not responding
• Frequent kernel panics or unexpected shutdowns

When a logic board is too damaged to repair, replacing it can:

• Restore full system functionality
• Extend your iMac’s life span
• Save money compared to buying a new system
• Preserve your existing files and setup

At Macguys, each iMac is assessed using Apple-standard diagnostic tools to ensure precise results before any part is replaced.

FAQs

How long does a logic board replacement take?

Most iMac replacements are completed within 1–3 days, depending on the model and part stock.

Is it worth replacing the logic board instead of buying a new iMac?
