    How to fix Owandy Medical Equipment when the display is off but the main switch is on?
    • J
      Jenny FisherAug 21, 2025
      If the display of your Owandy Medical Equipment is off when the main switch is on, first check if the LED on the keyboard is on and if you hear a beep when pressing the keyboard buttons. If the keyboard doesn't work, switch off the equipment and verify the flat cable connecting the CPU and the Driver board, check the integrity of fuses F1 and F3 (if present), and measure the presence of the main power supply. If no issues are found, replace the boards in this order: CPU, Driver board (including tubehead).

    What to do if Owandy Medical Equipment shows error E04?
    • T
      Teresa WolfeAug 23, 2025
      If your Owandy Medical Equipment displays error E04, indicating no emission (breakage in the filament circuit), measure the impedance value between '+' and '-' of Driver board - connector X2 (HEATER); this value must be lower than 20 ohm. If the value is greater than 20 ohm, remove the tubehead plastic covers and measure the impedance value between J3.IN+ and J3.IN- of Filament Voltage Regulator board. If the value is still greater than 20 ohm, disconnect the cables J3.Fil+ and J3.Fil- from the Filament terminal strip and measure the impedance value between them. If the measured value is lower than 20 ohm, replace the DP arm, otherwise replace tubehead and Driver board.

    • D
      Debbie NelsonAug 26, 2025
      If your Owandy Medical Equipment displays error E06, which indicates activation of the back-up timer, check the integrity of the flat cable connecting the CPU to the Driver board. Then, switch the system off and on again. If the error repeats after an exposure, replace the Driver board and the tubehead.

      Brenda WalkerAug 28, 2025
      If the Owandy Medical Equipment displays error E02, which means a key (different from X-ray button) was pressed at start-up, first verify that the button is not actually pressed. Then, switch the system off and on again. If the error persists, replace the CPU board.

    What should I do if my Owandy Medical Equipment shows error E07?
    • S
      Shawn WrightAug 31, 2025
      If your Owandy Medical Equipment displays error E07, which indicates protection intervention, switch the system off. Check the integrity of power cables between the tubehead and timer, and ensure there is proper insulation between them and GND (no short circuit). If the cables are okay, switch the unit on. If the error persists, replace the Driver board and the tubehead.

    What does error E12 mean on Owandy Medical Equipment and how can I fix it?
    • C
      Casey HendersonSep 5, 2025
      If the Owandy Medical Equipment displays error E12, which indicates the release of the X-ray button during emission, reset the error and repeat the exposure, ensuring you do not release the X-ray button before the buzzer stops. If the message continues to appear, replace the X-ray button.
