Apple Cinema Display Service Source

From RetroTechCollection

The Apple Cinema Display volume of Apple's Service Source is a 50-page service manual for the original 22-inch Apple Cinema Display, a TFT active-matrix LCD with a DVI connection, bundled with selected Power Mac G4 computers fitted with an AGP DVI graphics card. The PDF was produced in FrameMaker and distilled on 9 December 1999.[1]

What the manual says the product is

[edit | edit source]

The Cinema Display is a 22-inch (diagonal) TFT active-matrix LCD which, Apple says, was the largest flat-panel display ever released when it was introduced. It has a wide-format 1600 × 1024 native resolution, 24-bit colour, a 160-degree horizontal and vertical viewing angle, a power button that switches the display and the computer on together or puts both to sleep, a DVI 24-pin connector with TMDS signalling, two USB ports supplying 500 mA each, and a stand tilting from 10 to 30 degrees. It weighs 25 lb (11.4 kg). Apple calls it the first Apple display to support DVI. The display cable splits into three connectors: power adapter, USB and DVI.[2]

The Specifications chapter refers the reader to Apple's Spec Database and reproduces Apple's August 1999 specification sheet (L04178A): brightness 180 cd/m² and contrast ratio 300:1 (typical); resolutions 1600 × 1024 (optimum), 1280 × 800, 1024 × 640 and 800 × 500; antiglare hardcoat; 100-240 VAC, 50-60 Hz, less than 62 W operating through an external power adapter; order number M7478LL/A.[3]

What it settles

[edit | edit source]
  • A power light flashing three short amber flashes, repeating, calls for turning the display off and on, checking the DVI graphics card and installing the Apple Displays software. Two short flashes and one long flash indicate a backlight fault.[4]
  • A picture that has dimmed over time points to failing backlights. A screen saver can keep the backlights lit; sleep through Energy Saver turns them off, with the power light amber.[5]
  • Some behaviour is normal: a still image left for about 24 hours can leave a ghost that clears in one to two times as long with the display asleep; colours need 30 minutes' warm-up to reach full uniformity; letterbox bars on DVDs are set by the disc.[6]
  • Apple says to plug the computer into a grounded outlet before connecting the display, to protect it from electrostatic discharge.[5]
  • The exploded view lists the service parts: monitor stand 922-3941, power cord 922-3942, power adapter 922-3943, grip pad 922-3944 and hinge cap 922-3945. The front and back display assemblies are not offered.[7]

What this manual does not contain

[edit | edit source]

The Take Apart chapter covers the monitor stand (three screws at the hinge, 5/64-inch hex) and the grip pads only.[8] Apple serviced the display as a whole unit through mail-in or facilitated repair, and the manual has no procedure for the backlights, inverter, panel or logic board, no parts list below the stand and cables, no schematic and no component values.[1]
