    Hi sir:
    Please Reset the CPU.
    Attached is there the schematic how to do it.
    Search in Google your particular CPU that you have in the MOBO(motherboard) example 80836,
    look for Schematic Pins: a) RST =reset ++B) GND= ground , take a piece of wire make a bridge betwen 2 pins like
    appear in the schematic attached.

    hi Chock, yes, the problem is cpu reset in MOBO, we check already our cpu reset wire still connect to the ground.
    first we start the power. our cpu reset pointing like attachment picture with 3 (three) lamp on.
    there should be only 1 (one) lamp on ?
    our sm52 machine is 4 units, we try to change the cpu with the other sm 52,
    and its ok with the other and the lamp only 1 (one) on ?

    So, I tried to exchange the boards one by one onto the other machine and discovered that the broken part is the ESK board. Thank you for the help!

    ok sir.
    Great!

    The input/output control board ESK receives and
    processes the signals from the encoder IDS.
    The ESK provides the electronic control system with
    parallel and serial interfaces.

    Dear Sir,
    Please someone tell me where is the SM-52 one color CPU?
    And
    Do I reset the CPU while the machine is off? Or reset when the machine is running? Accurate information will be very helpful for me

    Hi sir:

    Normally is with cptronic compact in ZSK4B ELECTRONIC BOARD , the reset must be done in ON, otherwise, is ineffective the RESET.

    Sir, here is a file. There are pictures. Which pins should be shorted here? Know about this?

    We had an engineer come here and short these pins and the machine started, but I wasn't there when he did the short. So I could not see the pins. Sir, if you know please tell me, it would be helpful for me.

    Look for pins on SAK (memory) board.

    Hello CHOCK,

    I recently encountered the same problem with my system, and after reading through the forum, I came across your advice about performing a CPU reset to resolve the issue. However, I'm having some trouble understanding how to connect the reset to Ground using a wire.

    I've attached a photo for reference to show recent position and I was hoping you could provide some guidance or a step-by-step explanation on how to go about this process.
    Thank you in advance!

    sir is very Simple look carefully my schematic wiring diagrams

    1) Connect a wire or bridge from RST pin from CPU, to GROUND, any point of machine !! With the machine ON

    2) you must sure the Vcc or regulated power supply IS IN TOLERANCE 0.7% up or down

    3) Clock or CLK, must be have the exactly MHZ, you measure with a DMM( digital multimeter)>


    If point 2+ 3 is o.k the RESET MUST BE carried without problem, otherwise, will NOT work ...!!!!!
