I heat the solid on the back side of the PC boards with my work shop propane torch then blow the solder away with my air compressor air blower.
I move along pretty fast with the torch trying not to damage any parts. It is easy to miss a few places then I have to use my soldering gun to remove those parts I missed.
Most of the parts pull right off unless the wires are bent over. ICs always fall off easy but I have no use for those. I am only after certain parts like 1/2 watt resistors, power resistors, large capacitors, chokes, certain transformers, fuse blocks, heat sinks, mosfets, power transistors, steak on terminals.
I can get $300 worth of parts in 1 hours work. It takes longer to strip the PC board from the junk TV than it does to remove the parts from the PC board. There are lots of good wires and connectors I can reuse too.
Parts with bent over wires will need to be bent up straight with a tiny flat sharp end screw driver. Bending up 1 wire is enough to remove the part.
Transistor wires are always bent over. I don't often save these transistors I have no clue what they are and don't need them. Bargan packs of transistors are cheap so are 1/4 watt resistors and small capacitors.
I inspect the PC boards for parts I want if there are only a few I remove those then trash the board I don't waste time on things I don't need or things that are very time consuming to remove. It is rare to have damages parts even the diodes and transistors are still good. I test every thing before I use them, even new parts I buy sometimes parts are bad from the factory.
