Still working parts can be resold.
I think they're made with indium tin-oxide. Indium's about a $1 or so per gram.
Could not tell you, I've never went after indium from mixed oxides before, just its sulfate.

They have about 1 pound of number 2 copper in each screen that's about all I can scrap from them. The rest I give to the recycle yard. But this is for CTR monitors not LCD's.

kyle on what part of the monitor do you get the copper from? the wires inside of it or the monitor part?
cypher i can help with this because Ive done tons of these literal tons .
the copper there talking about is in monitors and its in several different places one being on the yoke of the screen . the other part is around the screen found at the bottom and sometimes under the screen so you'll have to take the screws out in order to get to the copper . this rope is taped with black electrical tape . now on the circuit board there's copper , and aluminum .
if you need any more help with this please (pm) me

thanks just whats i needed
I've found gold in laptop LCD screens. If you look real close or with a magnifying glass you'll see gold wires running around three sides of the board (nec versa s/33 and an old compaq). Fine as a hair, but quite a bit of it. I haven't processed any yet partly due to time and partly because its sealed under some kind of silicone. I'm still in the gathering, learning stage. Thanks to this site and the people on it I feel for the first time that I can actually successfully process the stuff I've hoarded. I've been reading and watching and rereading and rewatching. All I can say is
THANK YOU! This forum and you guys rock!

when taking the copper yoke off the tube do not twist it the tube will break wiggle it up and down
I took one of these apart today, was pretty simple to do. Yes it appears that there are tiny gold wires running along the edges of the glass & possibly making a grid inside of the glass. There were also two pieces of PC board in there that have a small line of gold plated fingers running the length of them. I will try to post some detailed pictures of it later.
To answer the original question, YES! There IS gold in there! :lol:

Brauer says indium can be electroplated from a solution of indium sulfate. Platinum gauze or foil anode, 20-35C temp, 10mA/cm^2 current density. "Smooth deposition is aided by hourly addition of 1ml of 1% gelatin or carpenter's glue solution per liter of electrolyte."
Probably suffices to peel apart the glass panes, wash away the liquid crystal and dye stuff, then leach the ITO with acid.
