The family (CRT) TV in the 80s came with a fold out schematic tucked in a pocket on the inside of the back cover.
And a CRT is not something to take lightly, as there is a sizable transformer in there to drive the electron gun and the magnets that deflect the beam.
What happened, imo, is the increasing used of ICs (first standardized ones, and later ASICs). This made it much harder to troubleshoot a device without access to an oscilloscope and the ability to order up OEM parts.
Before that a multimeter and some basic understanding of electric circuits could get you a long way.
