Yup, I find the crystals on Tv's, microwaves, handsfree telephones etc. Anything that needs a crystal to set the timing of something.
Monitors don't have them, so I think they have something to do with timing the electron rays of & on & maybe where & when the ray changes direction across the screen.
On a monitor, the computer will probably control this.
Depending on how old the TV is, the sort of crystal they use changes. Theres a sort thats in a can, like old transistors, most are flatter & larger dia.
Some Tv's have 2 or 3 crystals too, of different sizes & types.
Real old Tv's have a thin tube thats got red copper wire wound around its length, thats the sort of Tv that may have gold plated legs on some of its transistors. Its a old version of the crystal SAW.
Also, check any Tv channel changers, the sort where you had to get off your rr's to change channel. The contacts on these often have gold plating
I am saving then for PM refining, on the chance that the crystals contain silver.
I snap them off & 1/2 the time the legs stay on. They get their own jar which is 1 pint, & 2/3ds full. They might be reclaimable & the broken ones are for refining.
Unfortunaly I can't find some tin for the tin chloride 'gold test'.
