Exactly, my television is an ips lcd with an arm based programmable microcomputer with software that translates input signals for the display, LED backlighting and an internal power supply. Although, I wouldn’t be able to repair it, there are no spare parts.
Every washing machine has an embedded system that controls the washing cycle and needed programming for that. That’s not common knowledge and they rather put functionality in their marketing than function.
We need a right to repair and common instructions how to fix things, maybe that helps dissolving the magic.
