Scrapping Monitors & TV's (Plastic & Glass) - Page 3

Has anyone try to test LCD screens in broken monitors? That is, taking the monitors apart, pulling out the screens with all the wiring and testing just the screens? I googled a bit and found a place offering LCD test equipment. Not sure it's worth it, both in terms of time and money. If screens can be tested and are intact and without scratches and other physical damage, I am curious whether selling them on eBay as parts would make much sense, especially if the screens are from older and smaller monitors.



I've been offered a stash of about 100 broken LCD monitors, most of them with no visible physical damage to the screens. Selling them whole to out of state scrap buyers is not cost effective, so I am curious if this is the way to go instead...

Leaving trash around for 2 weeks is not high on my priority list haha

Not sure about the LCDs but I did save the power board out of the 32" LCD I took apart and the cheapest one on eBay right now is $35 upwards of $80 so I am going to throw the board on for $25-$30 should sell quickly.

Could the capacitors be dirty alum? I do that with mine.

I get dirty price for em

The clamps are also always non-magnetic I will have to spark test them I am assuming stainless, I got 25 monitors in yesterday so I had quite the repetitive system down.

I do like Mech, in the #2 bucket it goes, an my yard has never pitched a fit over it. Their good folks like that.

That or I'm just so awesome they overlook it cause it's me.

I know it does not pertain to glass and plastic but I have been going through a lot of monitors lately with the help of some glass disposal at a local dump, they take it willingly so whatever. I de-wire everything and then remove the light iron trays:



I then remove the transformers, aluminum heat sinks, metal shields, and any goodies with visible copper:



I end up with bins of broken up board much lighter and thinner, I need to do some more research around the site I remember seeing a thread identifying components. I know what IC chips look like there are the small micro chips and the taller ones with larger fingers that look older, pretty sure I can fill buckets of those and possibly some of these other components, once they are stripped the boards are worth less then light iron and one of my yards takes electronics as light iron so I will toss the stripped boards as light iron hah .12 cents a lb.

Well that was my point they are here until I figure out what to strip (ICs/Flats) but I need to find out what else off these boards people will buy off me because they will not be mid grade when I am done with them. I assume they will buy resistors, relays, transistors, etc in bulk?

In my experience it is possible to sell used resistors, relays, transistors, etc in bulk (100 count or better / by lb). The problem is they want them all tested and sorted by rating from what I have seen. As far as actual scrap value, there is very minimal recovery to be had. IC/Flats on the other hand have good resale around $5-6 / # last I seen.

I know relays have a copper driven motor in them with silver contact pads as any switch if you take them apart, I have read that the tiny capacitors (Monolithic Ceramic) yield quite well even as high or higher then ICs.

Fortunately for me, I just clip the cord and drop the rest off for $0.09/lb ...yes, including those darned old wooden console TV's. I know there are some goodies inside but if I strip all the goodies out then I have to deal with disposing of the carcas, ...tube and plastic, etc. This way just seems more convenient for me at least.

Good point, I have not seen anyone scrapping resistors and I did not plan on testing them for reuse. I save all my chips I know the top right is a flatpack but the top left I think is just an IC? These are all ICs right?





I haven't seen anyone scrapping crystals either, are these all crystals?
