iMac Aluminium (20″ & 24″) A1224/A1225 2007–2009 Forensic Technical Intake: iMac Aluminium (A1224/A1225) Target: 20-inch & 24-inch Models (2007–2009) 1. Primary Fault Classification Fault Group (A-Z) — Select Group — Audio & Sound Display & Backlight (CCFL) Graphics & Video (GPU) Logic Board & Cooling Optical Drive (SuperDrive) Ports & Connectivity Power Supply (Internal PSU) Storage & Booting Specific Fault — Select Group First — Describe this specific issue in your own words: 2. Device Condition (Day of Shipping) Why we need this: The aluminum iMac uses a heavy **magnetic glass panel**. If the chassis is slightly warped or the glass isn’t seated perfectly before shipping, the vibrations of transit can cause the glass to crack or the internal LCD mounting tabs to snap. Aluminum Chassis & Stand Condition (A-Z) Front Glass & LCD Panel State (A-Z) Rear Port & Airflow Grill State (A-Z) 3. Internal Power Supply (PSU) Diagnostics AI Technical Insight: These iMacs contain an internal power supply that generates significant heat. Over time, capacitors in the PSU can fail (bulge), leading to a ‘No Power’ state or a faint high-pitched whining. Forensic indicators like ‘ticking’ suggest the PSU is trying to start but hitting a short on the logic board. Power Status Condition (A-Z) Powers on and stays on Powers on but shuts down randomly No signs of life (No fans/No chime) Whining or Ticking noise when plugged in Do you see any internal diagnostic LEDs through the intake grill? 4. Graphics (GPU) & Thermal History AI Technical Insight: The A1224/A1225 models use MXM graphics cards (ATI/NVIDIA) that are prone to solder joint failure due to thermal cycling. Forensic symptoms include vertical lines on the screen, ‘checkerboard’ patterns, or the Mac stalling halfway through the Apple logo progress bar. Visual Artifacts (A-Z) No visual issues Vertical/Horizontal Lines Checkerboard / Blocks on screen Stuck at Apple Logo (Grey screen) Describe Fan Noise (Loud/Constant vs. Normal): 5. Data Backup Status Why we need this: These models use 3.5″ mechanical SATA hard drives. These drives have a high failure rate after 15+ years. The mechanical shock of shipping can cause a ‘head crash’ on an aging drive that was already struggling. Date of Last Backup Backup Method & Any ‘Clicking’ noises heard from the drive: 6. Previous Repair History Why we need this: Opening these iMacs requires heavy-duty suction cups. If a previous repair was done by a non-professional, there is a risk of torn VSYNC cables or stripped LCD screws, which can drastically increase the complexity of our repair. Has this device ever been repaired or opened? NoYesUnsure Approx. Dates, Who Performed Repair, and Result: 7. Mandatory Packaging Compliance CRITICAL: Due to the weight (up to 11kg) and the front glass, these iMacs must not be shipped in a single-walled box. The responsibility for secure packing remains entirely with the customer. Use a double-walled box with 4 inches of padding. If the stand is not supported, it can punch through the box. Seek professional guidance on large-format shipping. Describe your packaging method for this shipment:
