    If you have a multimeter you can always set it to the continuity setting and see if it has continuity. If it does, it's not blown. If it doesn't it's blown

    naw i dont have one of those. i guess its time for radio shack.

    if the led light on the power button is all that is funtioning on the monitor is that becuase of the fuse(possibly blown) or is it something else?

    Use any audio input...your pc or your pc amps will do.

    Turn the volume high enough such that you hear a hum whenever you touch the input...NOT THE GROUND.

    Now place the fuse so that one end touch the audio input, then touch the other end with your finger to hear the hum.

    If you hear the hum then you know you got continuity, i know it work cause I just tried it

    okay so if i read this right,

    audio input(mic? just where ever you plug the mic in),
    turn the system volume up, or the speakers?(probaly the system but not sure)
    do you feel the hum or would you put your ear to i guess your hand that is touching the fuse?

    The $15 multimeter might be best in this case

    My advice is to just buy a multimeter... Wal-mart has them for 10 bucks (automotive electronics section, where they sell the headlight bulbs and fuses and stuff). Any type of geek has to have a multimeter, comes in very handy.
