What We See Most Often in Our Workshop
After diagnosing thousands of Apple devices in our London laboratory, the three most common hardware failures our technicians encounter are:
💧 Liquid-Damaged PMIC Circuits
Coffee and water spills create active electrolysis under chip packages, shorting main power management ICs (PMIC). Ultrasonic chemical cleaning and targeted micro-soldering restore power without replacing the motherboard assembly.
🔌 USB-C Controller (CD3215/CD3217) Failures
MacBooks that suddenly refuse to charge or stay stuck at 5V on USB-C meters usually suffer from blown controller ICs caused by third-party hubs or voltage spikes. We desolder damaged chips and replace them under stereomicroscopes.
🔋 Heat-Induced Battery Swelling
Prolonged exposure to internal heat breaks down lithium-ion chemistry, causing gas buildup that pushes trackpads and screens outward. Prompt battery extraction prevents glass cracking and frame warping.
💥 Flexgate & Backlight Flex Wear
Repeated opening of MacBook display lids strains delicate display flex cables, resulting in stage light effects or complete backlight blackouts while external monitors function normally.
Common Apple Problems We Solve
⚡ MacBook / Device Won't Turn On
Power rail shorts on main 12V or 20V lines, shorted PMIC chips, corrupt BIOS/EFI firmware, or depleted batteries. Read our in-depth black screen diagnostic guide.
🔋 Battery Draining Fast or Swollen
Lithium-ion cells degrade after 500–1000 charge cycles. Review official guidelines on Apple Battery Service Information.
💥 Cracked OLED / LCD Screens
Impact fractures, color lines, or non-responsive touch layers resolved by installing tested replacement display assemblies.
💧 Liquid Exposure & Water Damage
Spills trigger rapid electrolytic corrosion under chip packages. Read about liquid damage recovery protocols and official Apple Water Resistance Guidelines.
Common Apple Hardware Symptoms
-
Apple Device Won't Turn On: Dead power rails, shorted capacitors, or depleted batteries.
- Apple Device Stuck on Logo: Corrupt storage NAND controller, damaged iOS/macOS boot loader, or failing battery.
- Apple Device Charging Slowly: Oxidized USB-C/Lightning pins or shorted charging PMIC.
- Apple Battery Draining Fast: High internal resistance in degraded lithium-ion cells.
- Apple Screen Flickering: Failing display backlight IC, flex cable wear, or thermal GPU strain.
- Apple Device Overheating: Blocked cooling vents, dried thermal paste, or shorted power components.
- Apple Liquid Damage: Corrosion bridging micro-capacitors to ground under BGA chips.
- Apple No Display Output: Intact power rails but blown backlight fuse or failed LCD assembly.
- Apple Green Screen / White Lines: Fractured OLED digitizer substrate or cracked glass ribbon.
- Apple Boot Loop: Physical home button, sensor flex, or power management circuit fault.

Frequently Asked Questions
Can Apple devices be repaired?
Yes. Most Apple devices - including MacBooks, iPhones, iPads, and Apple Watches—can be fully repaired. Component-level specialists can replace shattered screens, degraded batteries, charging ports, liquid-damaged circuits, and shorted logic board chips without replacing the whole device.
Will I lose my data during an Apple repair?
In most cases, no. Our component-level repairs focus on fixing individual power and screen components, leaving your onboard storage drive, photos, files, and settings preserved whenever hardware permits.
How much does Apple repair cost in London?
Initial hardware diagnostics are free. Component repair costs depend on the model and fault; typical screen and battery replacements cost significantly less than purchasing a new device or paying full replacement fees. For full pricing details, see official AppleCare Repair Information.
Is independent Apple repair safe?
Yes. Reputable laboratories like Terabyte Electronics use high-grade replacement components, ESD-safe work environments, specialized stereomicroscopes, and calibrated thermal tools to perform factory-spec repairs.
Can Apple logic boards be repaired?
Yes. Instead of replacing the entire expensive logic board assembly, our technicians perform micro-soldering under high magnification to replace individual shorted capacitors, MOSFETs, and Power Management ICs (PMIC).
Do you repair liquid damage on Apple devices?
Yes. We perform ultrasonic chemical decontamination to strip active oxidation from copper traces before re-soldering shorted power rails on MacBooks, iPhones, and iPads.
How long does an Apple repair take?
Screen and battery replacements for iPhones, MacBooks, and iPads are often completed same-day or within 24 hours. Micro-soldering and complex liquid damage diagnostics take 24 to 48 hours.
Do you repair Apple Watches?
Yes. We repair cracked OLED screens, swollen batteries, and charging faults on Apple Watch Series 3 through 10, SE, and Ultra models.
Do you repair older Macs?
Yes. We service both legacy Intel MacBooks (2012–2020) and modern Apple Silicon M1, M2, M3, and M4 MacBooks.
Can you repair M-series Apple Silicon MacBooks?
Yes. We specialize in component-level micro-soldering for Apple Silicon M1, M2, M3, and M4 logic boards, including charging PMICs, USB-C controller ICs, and backlight drivers.
Is Apple Watch water-resistant after repair?
When opening an Apple Watch, the original factory seal breaks. We apply a new precision perimeter adhesive gasket during reassembly to restore daily splash resistance for normal wear.
Do I need an appointment for Apple repair in London?
Walk-ins are welcome 6 days a week at our 136 Kilburn High Road store. You can also book online in advance or request doorstep courier pickup.
