Just bought a used Compaq Presario. The monitor keeps turning on and off. I have checked all connections and tried different power cords. Still the same.
OK All these Compaq's have a Power Supply problem, or a Horizontal Voltage problem.. meaning they are on the way out. The SMPSU's in these units often fail along with the Horizontal Drive Circuitry. I think it is time for a new one? Repair of such a unit would barely be "Ecconomical" IMHO.
