    Hello: I havent opened up this set as yet. It has a bright white raster and
    no OSD and some retrace lines are visible. My friend said maybe the CPU or
    Eeprom. Anybody have any ideas. I normally repair monitors so Im not sure
    where to start. Thanks in advance

    symptom?

    Check the power supply outputs, bias voltages to the CRT elements, screen
    supply, and high voltage. It is also possible that the CRT has a screen
    short.
