    Just messed up my lilliput.

    I was trying to install the lilliput into the indash housing from digitalww.com and it was one of the biggest mistakes! While trying to solder wires to the lilliput board for the button changeover, I followed digitalww.com's instructions and had used a tad bit too much solder on the connections that it ended up spreading all over the solder points on the board (where the cable connector was for the buttons.) Anyone know of way to remove the solder? or the whole piece so I can start over. Thanks. I'll try to post some photos.

    Use a solder sucker.. this is how they look like :


    Solder sucker

    The failure of soldering occurs often. In this case, the part or the wiring must be removed.
    I will introduce the instruments that can be used for desoldering.


    Solder pump

    This is the tool that can be absorbed the melted solder with the repulsion power of the spring that was built in with the principle of the piston.
    The usage is shown below.
    Pushe down the knob of the upper part of the pump against to spring until it is locked.
    Melt the solder of the part that wants to absorb solder with iron.
    Apply the nozzle of the pump to the melted solder part.
    Push the release knob of pump.
    Then the plunger of the pump is pushed up with the power of spring and solder is absorbed inside the pump.
    You need to do this operation quickly, otherwise the part gets damage by the heat. A little practice is needed.


    Desoldering wire

    This is made of thin copper net wire like a screen cable in a coaxial cable.
    Like water inhales to cloth, the solder is absorbed to the net wire by a capillary tube phenomenon.
    The usage is shown below.
    Apply the desoldering wire to the part that wants to take solder.
    Apply the soldering iron from the top and Melt the solder.
    The melted solder is absorbed to desoldering wire with a capillary tube phenomenon. At this time you absorb solder while shifting desoldering wire.
    When the solder can not be removed in the once, remove repeatedly while shifting the desoldering wire.

    Hope this helps and don't forget to suck.... hehehe suck baby .. suck ..

    I got a solder sucker from Dick Smith (aus) for $14 a while ago. I also have a solder pump (vacuum). Before I got these I would just heat up the solder than needs to be removed then while it is still hot and liquified I would knock the board so the solder flys off and away from the board.
    Another thing you could do is get some copper wire and use that to 'soak' up the solder. It would take a little longer but it gets the job done.

    I just used a desoldering wire to remove the unwanted solder. Going to fix everything right now, hopefully it will end up working.

    *whew* Problem solved. Everything is working fine now. I even took the time to make my lilliput have the auto turn on feature from coyote's instructions. Also, I have no soldering experience, but wouldn't recommend others to attempt to do anything to harm an expensive screen like I have! Thanks everyone who posted.

    I did the same thing but I just used desoldier braid, it always works for me.
    Mine needs to be updated.

    Yes, solder wick does a good job most of the times. For best results, place the iron tip on the wick itself and move the wick around to mop up the excess solder. I only use the solder sucker for removing solder from plate-thru holes.
