    Hi sir;

    You must reset the Cpu or Microprocessor, you must see what type INTEL of microprocessor is, if for example was 8086, you must search in Google the pin schematic for RST PIN( RESET PIN) AND PIN GND(pin for ground) trace a wire bridge between RST VS GRND PINS, and Done

    2)However you must sure a) the power supply in the CPU +5Vdc or 3.6Vdc new Generation, b) the CLOCK( mhz) measure with some DMM, like FLIKE that has for measure the Frecuency.

    Otherwise the CPU, can NOT work, by the lack of that parameters.

    Blessing

    Please proceed as I did indicated you must read in the main board .

    The CPU or microprocessor normally is located in REK boards

    If you have done all of what has been mentioned above, you will have to change the large card; see if the problem does not come from it.

    Please proceed as I did indicated.

    However you can clean it before , the Edge connectors boards, and tights all connector from the board, in order to get a good Troubleshooting.

    You must download the Data Sheet PINS, for the Cpu, and the pin that say RESET, must be with Ground, make a Bridge, as I did indicate in my schematic l

    The voltage, can be +5Vdc or 3.5vDC, see it in the Data Sheet
