4.5K & 5K Retina Display Glass Separation & Factory Gasket Re-Sealing
Servicing the razor-thin 24" 4.5K iMac or 27" 5K iMac requires cutting through factory structural foam adhesive tape without scratching the glass or severing delicate display ribbon cables. Whether replacing a shattered front glass, fixing internal LCD vertical lines, or accessing internal components, our technicians use specialized cutting wheels and reinstall genuine laser-cut perimeter adhesive gaskets to securely bond the display back to the chassis.
Internal Switching Power Supply (PSU) Diagnostics & AC Inlet Repair
When an iMac or Mac Mini completely fails to turn on, displays no LED status indicators, or shuts off immediately after pressing the power button, the internal switching power supply unit (PSU) is commonly defective. We test primary and secondary voltage rails, replace failed electrolytic capacitors and rectifier diodes, or install factory replacement power modules to restore clean, stable power delivery.
High-End Blower Fan Evacuation & Arctic MX-6 Thermal Paste Application
Desktop Macs accumulate substantial ambient dust inside their downward-facing intake vents and blower fan ducts over years of continuous operation. This dust blanket causes processor overheating, fan whining, and performance lag. We thoroughly de-dust all internal fan blowers, clean copper heat sinks, and apply high-grade Arctic MX-6 thermal compound to the CPU and GPU dies for whisper-quiet thermal performance.
Logic Board Ultrasonic De-Oxidation & SMD Micro-Soldering
Desktop Macs can experience hardware failure from electrical power surges, thunderstorm lightning strikes, or insect ingress. Our Hyattsville micro-soldering engineers diagnose blown surface-mount diodes, shorted ceramic filtering capacitors, and corrupted firmware chips, repairing the original Apple logic board and saving you hundreds of dollars compared to board replacement.
High-Speed NVMe Storage Upgrades & APFS Data Recovery
For Intel iMacs and Mac Minis running slow mechanical hard drives or fusion drives, an internal solid-state drive upgrade transforms system responsiveness, reducing boot times from minutes to seconds. On Apple Silicon Mac desktops experiencing boot failure or flashing folder icons, we perform advanced data recovery to extract vital personal documents, photos, and business archives.
Frequently Asked Questions
Can you repair an iMac that will not turn on at all?
Yes! We diagnose power supplies, power button micro-switches, and motherboard power delivery circuits. Most power failures can be repaired cost-effectively by replacing or repairing the internal power supply unit (PSU).
How do you open an iMac without cracking the glass screen?
We use professional Apple display separation tools with precise depth guards to cut the factory adhesive foam without stressing the glass or damaging internal display flex cables, and we reseal it with genuine OEM adhesive strips.
Can you upgrade the storage on my older iMac or Mac Mini?
Yes! For supported Intel iMac and Mac Mini models, we replace slow hard drives with blazing-fast SATA or NVMe SSDs and clone all your existing data, resulting in a dramatic speed boost.
How long do desktop Mac repairs take at your Hyattsville shop?
Diagnostic evaluations are completed within 24 hours, and standard repairs such as power supply replacements, thermal cleanings, or drive upgrades are typically finished within 1 to 2 business days.
