    Flat Panel Monitors for Parts and Repair

    Do any of you save parts from monitors to use for repairing others? If so, what parts do you mainly look for and keep? Can you know if the saved part is still good, and how?

    I've been sorting though and testing flat panel monitors, and due to doing some Googling, have found that many times a specific problem will likely need only the replacement of a specific part, or board. In the case I found this fix, I also found a list of likely donor monitors(of several different brands) which used the same board. I'm not far enough along in this project to start replacing capacitors, but might not be that far from it, and have certainly seen a number of them bulging.


    The most common problem I've found so far is the "two seconds to black screen", which is likely an inverter or backlight, which in my case simply needs a single board from a donor, which can be found on several different brands and models.
    The next most common problem I've found is no lights anywhere, in which case I will first be looking for a blown fuse.

    It appears the most likely ones to be working are the smaller 15" ones, which were likely replaced with larger ones and discarded. I'm also keeping these as possible FreeCycle gifts to someone who needs one badly. The scrap value of these is likely quite minimal, and may be a good way to connect with people who may have other electronics or an old computer in the closet they hadn't thought of.



    I've been using a spare computer, just leaving it running, and hooking up each monitor to see if it's working. You don't need to power the computer down each time you switch monitors. I do however, unhook the power first, and hook it back last, just from an excess of caution.

    I was fixing these and saving parts etc but the resale market is only about $10 each locally to move them quick, it's just not worth my time. I'd save everything including the screens if they aren't scratched or broken.

    $10 for a 17 inch? What do you mean by save everything? Even the plastic? Save for how long? I've seen where someone I think buys the screens, is that stripped bare screen?

    I think I have a bad inverter on mine. If anyone comes along a JVC LT-32WX84 I could use the lower inverter board

    I got a Sony one. An no I don't save parts. I save enough crap, I don't need more, specially for something most people just go out an rebuy even cheaper. Heh.

    Anyone needs parts from the Sony one, your welcome to it, unless I scrap it first. Slim chance as I got stuff I got to get to before it.

    An yea..I'm sure it's an easy fix, but I break things, I'm not a tv repair man. Heck if you think you can fix it I'll sell the whole **** thing. lol. Big sucker to.

    If it is a large enough monitor or TV, i will open it up and see what is wrong.
    Usually it is a shorted electrolytic capacitor (we call 'em Cow Pastures)
    Replacing caps is an easy fix.
    Basic soldering skills are necessary.
    I have rescued a lot of nice monitors like this.
    I often salvage components from other scrap boards to repair monitors.
    TV boards, motherboards, power supplies all can be donors.
    If you were doing it as a repair business, you should buy new caps.
    I just gotta salvage - that's how I roll.
    If it is time consuming, I save the circuit board, ac adaptor if any, and any metal.
    The rest gets recycled. Not thrown out.
    There is not enough $$ in the 15" displays to bother with
    To each his own!
