What's Wrong With This Dead Vectrex?

About this video

What is wrong with a totally dead Vectrex bought as junk on eBay? The maker diagnoses the fault, after warning that the CRT can hold a deadly charge even when switched off.

Good to know: The tube and flyback hold a potentially lethal charge after unplugging. A knocked or cracked tube can implode, so protect your eyes and never lift it by the neck. Mains voltage inside. The channel says this is not instruction.

Why watch it

Totally dead and bought as junk, the Vectrex gives no symptom to work from beyond nothing happening, so the interest is the diagnosis path.
