Sony BVM 1311: The 90s Trinitron Studio Monitor - Troubleshooting & fixing lots of problems

About this video

Why does a Sony BVM 1311 monitor flash? The channel suspects a bad tube at first, but notes something smells fishy, and goes on to check the tube and other components.

Good to know: The tube and flyback hold a high voltage charge after unplugging. A knocked or cracked tube can implode, so protect your eyes and never lift it by the neck. Mains voltage inside. Soldering brings burns, fumes and lead.

Why watch it

Timestamps let you jump to testing, and a 240p test suite is linked for checking CRT displays. The job has lots of problems, not just one, so it is a layered diagnosis.
