Troubleshooting
4.1 Introduction
This chapter lists the problems that may occur during use of the monitor and recommended measures. Refer to the
table in this chapter to check the monitor, confirm and fix these problems. For more information about the
troubleshooting, please contact Mindray service.
4.2 Part Replacement
For the monitor, the PCB, main parts and components can be replaced. For the LCD or touch screen fault, only the
front case assembly can be replaced. Once the faulty PCB is confirmed, replace the PCB according to the operation
guide in Chapter 6
Disassembly and Repair
. Then, confirm that the monitor can operate normally and has passed all
the performance tests. For the information about replaceable parts, refer to Chapter 7 Parts .
4.3 Check before Powering on the Monitor
After the AC power supply is connected, check whether the AC indicator is turned on. If not, confirm whether the AC
cable is connected to the socket and monitor reliably. If both the AC external power supply and power cord are
connected normally, but the AC indicator is off, the AC-DC power module or main control board of the main unit may
be damaged. Now, you need to run the monitor on battery powered on. If the monitor cannot be powered on, the
main control board may be damaged or the internal board is abnormal, resulting in power supply protection. If the
monitor can be run on battery power, the AC-DC power module is damaged.
In addition, check the appearance for damages before powering on. Particularly, when the touch screen of the screen
assembly is damaged, stop using the monitor immediately.
