    I opened up a flatscreen LCD computer monitor and all there was inside was 2 small circuit boards and some thin steel sheet metal on the back of the screen.

    Did not even seem worth the time to take it apart.
    Do you have any pics of the one you got?

    I'm still waiting for my first flat screen TV. Just picked up my first 2 LCD monitors today and dug into them. Not bad. Don't know how it would compare to a TV, but I like it.

    One had more goodies than the other, but the copper and aluminum is always welcome here. Don't know enough about gold to say there's a lot in there, but it is on one of the boards in each monitor. Maybe even a high grade board, though I'm not sure, it looks like one of the boards in each monitor has a small processor with a heat sink around it.

    I pulled a LED one apart, it had a several long thin flouro tubes inside it to provide light & several sheets of plastic to help it get about.

    There were 3 IC boards & a long thin boards down two sides of the screen.
    The 3 boards had a little gold on them & the 2 long thin ones had a full length row of small gold contacts on its edge, this connects to the sides of the glass LED screen.

    There IS gold, not much as I expect modern TV manufactures to really skimp on gold because of the price.

    You think the layer of gold is thin, see whats on the side of a plastic chip packet, itsa layer of Ali, you can hardly see thru it but its still a layer of Ali.
    If they can plate plastic with a layer this thin, expect them to do the same with Gold....

    Eesakiwi i pulled apart an LED flat screen, 60 inch i believe, had a nice amount of goodies. Didnt know what those "glass tube thingies" (as i called them) were. Thanks!

    The normal flat screen monitors normally arent worth the hassle.

    Those thin tubes might be these

    CCFL (Cold cathode fluorescent lamps)

    Cold Cathode Fluorescent Lamp belongs to gas discharge lamp, there are rare gases and a slight amount of mercury inside, electron hit mercury, mercury will emit 254 nanometer ultraviolet

    Yes the thin glass tubes are CCFL lamps that backlight the screen.

    Be careful with them if you are trying to repair the screen. They operate at very high voltage and will give you a nice jolt!

    Yeah, I've found steel, gold and a whole lotta plastic. T-Con boards seem to sell on ebay. In hindsight, I think you'll get so much more from ebaying for spares/repair.
