    Hi sir;

    Normally, you must test the 1( battery and see if the Red LED is LIT up you must repace ASAP, with the same characteristic

    2) the CPU , where is located the CPU, or Up microprocessor in the POT vr1, try t adjust to 4.8Vdc, of course previously you must measure the 1) VCC from the CPU or UP 2) Clock, look in the Google, Bing, Yahoo ,etc the pins schematic for CPU or UP that you machine has

    3) Clean very weel the edge connector of electronic board, and look, for loose wires, dirty, corroded, flat or ribbon cable loose of faulty.

    4) the Reset will NOT effect, if you do NOT measure the Vcc+Clock in MHZ., the power supply must be in tolerance from 0.7% up or down, otherwise , you must repair or replace it.
