COMEN Medical CM1200B ECG Machine Display Interface Board Screen Flex Cable AWM 20624 80C 60V VM-1

COMEN Medical CM1200B ECG Machine Display Flex Cable AWM 20624 80C 60V VM-1 is a key flexible circuit component that connects the host motherboard to the display screen, used to transmit video signals, control instructions and backlight power. It is one of the key components in the device, capable of transmitting signals and helping the display screen display parameters for medical staff to view. Even though it is a used product, it has been professionally tested to ensure usability.

• Signal transmission: Responsible for transmitting ECG waveform, analysis results, operation interface and other data from the mainboard to the LCD screen.
• Backlight control: Supports key operation with backlight, the cable needs to synchronously transmit backlight power supply and control signal.
• Structural adaptability: Because COMEN CM1200B is a non-touch screen design, the cable only needs to carry the display output function (no touch signal layer), which simplifies the interface complexity.

During the use of the COMEN CM1200B electrocardiograph, you may encounter some faults. The following are some possible faults, causes and solutions:

• Common fault manifestations:
  • The screen flickers, is distorted or completely black (signal transmission is interrupted)
  • The backlight is not on or the buttons are unresponsive (power supply/control line failure)
  • The lead detachment prompt diagram is displayed abnormally (affecting clinical operation)
• Maintenance suggestions:
  • Please use the Flex Cable designed specifically for the CM1200B, not the CM1200, otherwise the device may be damaged due to incompatibility.
  • When replacing, the main unit housing needs to be disassembled, and the operation involves precision interfaces. It is recommended that professionals perform replacement/repair operations.
