DIY LCD Backlight Repair

Posted by ScuttleMonkey on from the franken-monitor-to-pillage-local-town dept.

Bill Nye (not the science guy) writes to tell us that InventGeek has an interesting article on do it yourself LCD backlight repair. From the overview: "Those of us that have used LCD monitors for a while know that over time the backlight starts to dim and will eventually completely fail. Leaving you with some electronic scrap that you could sell on eBay for 35 bucks or so. Well for less than $20.00 and about a half hour of your time you can replace the backlight and rejuvenate that monitor to as good as new condition."

  1. Ahem, about that "mercury" by Ancient_Hacker · · Score: 4, Interesting
    A few words about that *deadly* mercury vapor:
    • Have you ever broken a fluorescent light?
    • If not, go do so right now.
    • Still here?
    • Of course you are.
    • the amount of mercury vapor in a four-foot fluorescent tube is about, hmm... lesse a pint's a pound, never eat anything bigger than your head, ..... >.
    • I ma ke the volume of a 4foot 1.25" diameter tube versus a 17 inch 0.15 inch tube as about 150 times.
    • So if you survived the overhead light breeaking, you're not going to be much worse off breaking a little LCD CCFL tube.

    Sheesh!

    Required disclaimer: When breaking fluorescent tubes, do so in an area with some ventilation. Do not huff the tube. Do not lick the insides of the tube.

    Exactly.

    Mercury and Asbestos hysteria is far out of proportion to the risk.

    (scroll down) shows a guy sitting (floating) in a vat of it. My high school chemistry teacher used to demo mercury by putting a little puddle in each childs hand.
