Service Manual [1]

Variant of the Philips/Commodore CRT:1084-P, itself based on the Philips CRT:CM8833 and CRT:CM8850, adding stereo sound and a headphone jack.

NTSC version can be identified by the 120 V power input, front hue control, and 4 rear controls for size and position. PAL version is 220 V, lacks a hue control, and moves the horizontal position knob to the front.

Digital input is for CGA-compatible signal (5 volt RGBIHV), linear input is for SCART-compatible signal (RGBS). Very early production DAC card (possibly not used in 1084S-P) also supports Apple XRGB, selected via a dedicated pin unused on later versions. S-Video support (called LCA: Luma/Chroma/Audio) pre-dates its name or the de facto standard mini-DIN connector.

VCR switch increases horizontal sync for better compatibility with unstable signals (ie analog videotape).

The PCB and back cover can readily be upgraded with a SCART socket, as well as with a green-only filter circuit (present on other variants of the CM8833/50).
