    Hi everyone,

    If you have a Belinea 102020 monitor and you're missing a color (green
    in my case) you could maybe easily repair it.

    In my case I had to replace a SC3953 transistor at the CRT neck board.
    Actually I replaced all 3 transistors. These transistors are used for
    amplifying the Red Green and Blue color signals. You need to remove
    some soldering joints at the metal shield to be able to push the metal
    shield away from the CRT neck board. Please note there is also a
    soldering joint behind the sponge and under the metal shield. The 3
    transistors can be found on the top of the CRT neck board with the
    label at the other side, which are easily accessible.

    Please also read the "Notes on the Troubleshooting and Repair of
    Computer and Video Monitors" webside at:

    Good Luck!
