    As a new member, I apologize for starting off as a beggar. My experience with board components consists of having replaced two capacitors. If my boss repairs this board, he'll have someone qualified do the soldering,

    I'd greatly appreciate any information you can give me in selecting replacement voltage regulators for this board, which was pulled from a Hannspree 28" LCD monitor. I sent this photo [​IMG]to Mouser.com, who were kind enough to cross reference to the following page:

    Here are photos of the board, which has the vr's removed:

    TIA for any information you can provide regarding the voltages of the originals, and/or where I can locate another board.

    Hi MisterB
    welcome to EP :)

    the LML1084 is a 5 Amp low dropout voltage regulator
    http://www.ti.com/lit/ds/symlink/lm1084.pdf

    they are available in 3.3 V and 5V
    so the 2 above that you have is one of each

    the 1084-33 is a 3.3V one
    the 1084 is a 5V one as it has no -33 marking :)
