Apple 16" Color Display
The Macintosh 16" Color Display is a Trinitron colour monitor with a 17-inch tube and a 16-inch viewable image, sold by Apple from October 1991 to April 1994.[1] It runs at 832 × 624 and 75 Hz, and its tilt-and-swivel base carries three ADB ports and sound connections so that the keyboard, mouse and microphone can plug into the display.[2] The model number on the back is M1298.[1]

The 832 × 624 mode needs video that supports it; Apple's 1993 guide mentions the 16-inch display among the large displays supported by the PowerBook Duo MiniDock, and lists it with the 12-inch and 14-inch displays for the external video of the PowerBook 160 and 165c.[3]
Hardware
[edit | edit source]The display has a main board, a CRT/video board on the tube neck, a separate focus control board carrying the FOCUS and H.STAT controls, a contrast/brightness board, an AC inlet assembly and a base board for the ADB and sound connectors.[5]
| Part | Apple number |
|---|---|
| Main board | 661-1634 (Rev. A) or 661-1671 (Rev. B) |
| CRT/video board | 661-1635 |
| CRT assembly | 076-0563 |
| Focus control | 982-0139 |
| Contrast/brightness assembly | 982-0127 |
| AC inlet assembly | 076-0077 |
| Fuse | 922-0516 |
| Base PC assembly | 981-0029 |
| Video cable | 590-0734 |
The two main board revisions are replaced like for like: a board with vendor part number A-1335-028 printed near connector D3 is the original (661-1634); otherwise it is Rev. B (661-1671). A replacement CRT/video board must have switch SW1 set as Apple shows, towards the neck of the tube, or the colours cannot be set correctly and green is oversaturated.[6]
Known faults and normal behaviour
[edit | edit source]Apple's service manual opens with a chapter on environmental distortion: large monitors bend near metal furniture and jitter near fluorescent lights and appliances, and Apple says to move or turn the display before adjusting it or swapping modules.[7] Two thin horizontal lines, a quarter to a third of the way from the top and bottom, are the support wires of the Trinitron aperture grille and are not a fault.[8] A green vertical line at the left of the screen and an overall green cast are listed against the setting of SW1.[8]
No component-level repair reports or capacitor list for this display have been found, and Apple's documents give no component values.
