Same advice as disassembling a very old CRT TV - leave it unplugged for 24 hours for all the capacitors to discharge if you’re wanting to reuse the bits for any projects that you’re doing. Otherwise, spicy voltages may still be present.
Just one minor quibble, leaving a old TV unplugged for 24 hours does not make it safe. Capacitors can hold a deadly charge for days, months, or even years.
You’ll give me traumatic flashbacks to our electricians checking the industrial overload settings by dropping a spanner onto the busbars. If the switchgear tripped out before the spanner melted, then the settings must be correct.
I’m reminded of that video of the two guys in an attic with a massive transformer and then using the ends to melt steel tools. I also wonder what wonderfully fun lung diseases those guys ended up with
Many times the fix is simple, like a spuriously blown fuse. And the capacitor that holds charge after unplugged does not for long thanks to the discharging resistor, although best not rely on that and use a screwdriver to short it, even basic ones can handle 2000 volts but extending one with a stick is always possible.
Obligatory please never disassemble a microwave no matter how cool a “magnetron” sounds

Just like microwaves, most of them have discharging resistors, and are easy to discharge safely manually by looking up how and being careful.
You don’t have dedicated high voltage discharge device, a screw driver taped to a big not conductive stick?

How else am I supposed to check if the “kill your entire family twice” capacitor out of a microwave is angry or not?
Round a nut? You go into the busbar box.
There are also videos online on how to safely discharge them, just in case there is still power left
