Ludlow, all three you mention are very low on precious metals, PC power supplies could be use by the hobbyist for electrolysis.
Other that that, it's mostly just copper and aluminum cooling ribs.
To get rid of tv's, monitors and LCD screens in my country, you have to pay for them!
Are the screens still attached or is it PCB's from said parts?
A scrapyard or ebay will be a more profitable place for you. Shipping such low value scrap will decrease any profit imo.
