Macintosh TV Service Source
The Macintosh TV volume of Apple's Service Source is a 139-page service manual for the Macintosh TV. The Overview says it "contains complete repair procedures for the Macintosh TV" (PDF p. 3). The PDF was produced in FrameMaker and is dated 4 December 1995.
Like other Service Source volumes, it works at module level: specifications, symptom charts, take-apart procedures, battery test, display adjustments and an exploded view with module part numbers.
