    If your ultrasound machine has problems, please see as follows:

    1. The keys don’t flash any light and there is no any image and character displayed on the screen after turn Power switch.
    Check the power line to make sure that it is connected with the machine well
    Check the voltage of the socket and make it in a normal station
    Check the power switch to make sure that it is turned on, whether the protective tube is burnout, whether have correlative voltage output from power switch.

    2. The keys flashes green light but there is no any display on screen after turn on the power switch.
    To check whether the brightness regulation resistance is adjusted to the minimum
    To check whether the output voltage of the power switch is normal
    To check whether the monitor voltage is normal.

    3. There are characters and sector but there is no signal after turn on the power switch.
    To check the contrast grade regulation resistance and Full gain regulation resistance to make sure it is controlled by minimum ( change the contrast grade regulation resistance and Full gain regulation resistance ).
     
    4. The keys flashes green light but there is no character and no sector on the screen, and the problem is still can’t be resolved after adjust related parts.
    To check whether the quartz vibrator of the data tablet is librated
    Whether the voltage regulator tube of the data tablet is correct
    Whether the monitor is in a good state. (Or replace a data tablet)

    5. The machine works normal but there is an unsteady display on screen.
    Please check single chip(SCM), 27C01, 1K50 to make sure them is installed well
    Whether have some rosin joint
    Press the “Reseat” key to restart the machine
    Replace a data tablet.

    6. The machine works normal when turn on the power and characters are displayed on the screen but there is no sector.
    To check whether the 1024 and 1K50 is forgot to weld or rosin joint( replace a data tablet )

    7. The machine works normal when turn on but the displayed characters are not right.
    To check whether the 2568 and 1K50 is forget to weld or rosin joint( replace a data tablet )

    8. The machine works normal when turn on but the cine is abnormal.
    To check whether there is a rosin joint between 57V56820 AND 3256. ( replace a data tablet )

    9. The machine works normal when turn on but the displayed time is wrong.
    To check whether the 12C887 is welded well or replace a data tablet.

    10. The machine works normal when turn on but the panel can’t work (at that time, only the “reseat” can work)
    Firstly check whether there is any keys are pressed (if there is a key be pressed, the panel can’t work),
    Or check whether the winding displacement of the panel is damaged and plug is installed well.
    Whether the voltage of voltage regulator tube is correct
    Whether the quartz vibrator of the data tablet is librated
    Whether the operation of dynatron is normal
    Whether the 74HC125 of the data tablet is rosin joint or normal, otherwise you should replace the old panel.

    11. The machine works normal when turn on but the signal of image is weak
    To check whether the 125V voltage is normal
    Whether the DF, TGC, Full gain and the contrast grade is normal
    Whether each correlative signal circuit is normal.

    12. The machine works normal when turn on but there is a black stripe in image
    To check whether all the shooting signal of the data tablet are working normally
    To check whether winding displacement is installed well.
    To check whether the output of 75365 is normal
    Whether the operation of enlarge module is normal
    To check whether the socket of probe is installed well
    Then re-press the “reseat” key or change a shooting panel.

    13. The machine works normal when turn on. but there are black lines in image
    Check if the switch signal of the data tablet is working normally.
    Check whether winding displacement is installed well
    Whether the operation of switch module is normal
    Whether the probe is installed well(replace a shooting panel and a probe)

    14. The machine works normal when turn on but there is interference whether the grounding line is installed well
    Check whether have some other machines which may have strong shooting signal, or some network source interference to the ultrasound and find it to turn off it.
    If there are some problems with probe, replace it with the same model, and the same batch. Please note that the probe should be taken lightly, no vibration, no damp.
    Don’t insert and pull out the probe when the machine is working.
