About this video

A faulty 486 motherboard, later identified by the maker as a PCChips M921, is troubleshot by Tony359 with advice from the Vogons forum, and a reference page is linked.

Good to know: Board level work usually means soldering: burns and fumes, and old solder contains lead.

Why watch it

At 50 minutes on a single board, this is a long troubleshooting session, and the maker frames it as an attempt at a repair. The board's reference page lists its details.
