Overview<\/h1>\n

The Philips VP415 laserdisc player used by the BBC Domesday project is modular and contains many plug in boards.\u00a0 Each board performs a specific function (or set of functions) within the player.\u00a0 Here are the modules organised by their alphabetic identifier.\u00a0 Click on any of the modules for more information:<\/p>\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n

Module Layout<\/h1>\n

The module layout in the player is shown in the following picture:<\/p>\n

NFR\/Fusible resistors<\/h1>\n

Nearly all of the modules in the VP415 contain Non-Flammable Resistors (also known as fusible resistors).\u00a0 These resistors can be identified physically by colour as they are axial resistors with grey bodies.\u00a0 In the schematics the NFR resistors are marked with a black triangle containing the '!' symbol.<\/p>\n

Note that these components are safety components and are not the same as normal axial resistors.\u00a0 Under no circumstances<\/strong> should you replace them with standard resistors!<\/p>\n

Vishay make a range of NFR resistors suitable for repair and replacement.\u00a0 The manufacturer part numbers vary based on packaged quantity; searching for the following part numbers should provide a range of acceptable replacement parts:<\/p>\n
