iMacs can develop faults ranging from failed storage drives and overheating to display issues, liquid damage, logic board faults, and software corruption.
At Dead or Alive Technology, we provide diagnostics-led iMac repairs for home users, creative professionals, students, and business customers. We work on Intel-based iMacs, Retina iMacs, Fusion Drive systems, SSD upgrades, and selected Apple silicon devices where serviceable.
Based in Wishaw, North Lanarkshire, we support customers across Glasgow, Edinburgh, the Central Belt, and UK-wide where suitable. Our approach focuses on accurate diagnostics, transparent communication, quality repairs, and long-term reliability rather than guesswork part swapping.
Diagnosis for dead iMacs, no power faults, failed startup, black screens, boot loops, and intermittent power issues.
Diagnostics for slow startup, freezing, spinning wheel issues, ageing hard drives, Fusion Drive failure, and software problems.
Replacement of older hard drives and Fusion Drives with SSD upgrades for significantly improved performance and reliability.
Internal cleaning, thermal servicing, cooling diagnostics, fan issues, overheating shutdowns, and temperature-related faults.
Diagnosis for screen flickering, no display, backlight faults, display lines, image distortion, and graphical issues.
Advanced assessment for liquid damaged iMacs including corrosion inspection and board-level fault tracing where viable.
Advanced board-level repair solutions for logic board faults, power issues, charging circuits, and component failures.
macOS corruption, failed updates, startup problems, software crashes, account issues, and operating system recovery.
Assessment and recovery options for failed drives, corrupted storage, inaccessible user profiles, and non-booting iMac systems.
We service many Apple desktop models including:
Not sure which iMac you have? Contact us with the serial number or model information and we can advise.
We properly diagnose faults before recommending repairs, upgrades, or replacement parts to ensure the correct solution.
Experience with common iMac faults including storage failure, overheating, display problems, and board-level issues.
You receive straightforward advice, realistic expectations, and transparent pricing throughout the repair process.
We prioritise reliable repairs and correct fault finding rather than rushed turnaround or unnecessary replacements.
Standard diagnostics are typically £30 and may be deducted from the repair cost where appropriate if the repair proceeds. Advanced diagnostics, liquid damage assessment, or board-level fault tracing may require a higher diagnostic fee.
Yes. Many older iMacs benefit significantly from SSD upgrades, thermal servicing, software optimisation, or replacement of failing storage devices.
Yes. We offer liquid damage diagnostics and corrosion assessment. Success depends on the extent of the damage and how quickly the device was powered down after exposure.
In many cases, yes. We can assess failed drives, corrupted storage, and non-booting systems to determine available recovery options.
Yes. We provide advanced diagnostics and selected board-level repair options for compatible logic board faults.
Repair time depends on the fault, testing requirements, and parts availability. Straightforward upgrades may be completed quickly, while intermittent faults or board-level diagnostics can require additional time.
