Component-Level Repairs That Save Devices Others Write Off
Last updated: April 2026
When Apple or other manufacturers quote thousands for a logic board replacement, we often repair the actual fault for a fraction of the cost. Our technicians perform component-level diagnostics and repairs on MacBooks, iMacs, and PC motherboards.
Schematic-based fault finding to identify the exact failed component.
Precision soldering under microscope to replace tiny surface-mount components.
Fix charging issues, no power problems, and battery management faults.
Graphics chip issues including reballing, replacement, and display circuit repairs.
Repair corrosion damage and replace components affected by liquid spills.
Repairs often preserve your data - no need for restoration from backup.
Simple steps to get your problem solved quickly and professionally.
We identify the specific fault using schematics and diagnostic equipment.
Clear quote for the repair. Often a fraction of board replacement cost.
Precision micro-soldering to replace or repair the failed components.
Thorough testing to ensure the repair is complete and reliable.

"Apple quoted £600 for a new logic board. These guys fixed the actual fault for £180. Works perfectly. Incredible skill."

"MacBook Pro wouldn't charge. They diagnosed a tiny component failure and fixed it same week. Saved me a fortune!"
Maria Santos

"iMac had a GPU fault causing display corruption. Apple said it couldn't be fixed. PC Macgicians repaired the board and it's been running perfectly for six months."

Most repair shops replace the entire logic board. We go further:
Schematic-based diagnosis
We use manufacturer schematics and board view software to trace faults to individual components — not just swap whole assemblies.
Micro-soldering under microscope
Tiny surface-mount components — capacitors, MOSFETs, inductors — are replaced with precision equipment not found in general repair shops.
BGA rework
Ball grid array chips (including GPU reballing) are handled with hot air rework stations for clean, reliable results.
Power rail testing
We measure power rails against schematics to find short circuits and open faults quickly, rather than guessing.
This level of work takes longer than a board swap but typically costs 50–80% less.
Two often-overlooked benefits of board repair over replacement:
Even if we can't repair the board, we'll give you an honest assessment and can often recover data separately.

Starting from
£95
Board repairs start from £95 for simple fixes. Complex repairs quoted individually based on diagnosis. Often 50–80% cheaper than full board replacement.

MacBook in Wandsworth SW18 with an intermittent logic-board fault. We carried out a board-level refurbishment rather than a full replacement, restoring stable operation.
MacBook Air in Putney SW15 returned with a new no-power fault unrelated to the previous repair. We diagnosed and refurbished the affected area honestly — service charge only, no upselling.

Not all motherboard failures mean a write-off. This guide explains which faults are fixable, what component-level repair actually costs in the UK, and when replacing the board or the machine makes more sense.
