    got it on ebay but does not power up--i have a basic knowsledge of electoics like i can use a scope and dvm--im getting the cd service manual ( when i do i will post it here )

    i now there are test points on the board and i plan to do this
    unplugged!!
    1. see if there is a fuse in it or if the fuse is broken
    2. take it apart
    3, see if the power switch works --hook ohm meter across it.
    4. using a magnifier scrutinize all surfaces of board and general visual check up
    if all is ok
    here is where i need help

    using the service manual--check voltage ( using my digital dvm--solid state one) of all test points and check them off--what is best way to do this?--mark with marker on board say with a red marker that which i tested ? or?
    ay direction here would be helpful

    thanks
    peter

    Sounds like an ok plan & sequence.
    Testpoints are for use with power on.
    Start with checking the power supply voltages.
    Using a marker like that is pointless, just write the results on a paper instead.
