I am working in IR3225 the problem is frequent down of control panel inverter PCB.Only after two to three months the pcb gone .Please suggest

The new style LCD Inverter PCB (Part Number FM4-6690-010) now has a jumper, JP4, on it.
Also, there may be one of two different style LCD's in the machine, each with a different style connector to the Inverter PCB. There are two positions for jumper JP4 depending on which LCD you have.

If the LCD Display's connector plugs into J2 on the LCD Inverter PCB, the jumper for JP4 should be positioned all the way to the left for the LCD Display to work properly. Please refer to the picture below:

If the LCD Display's connector plugs into J3 on the LCD Inverter PCB, the jumper for JP4 should be positioned all the way to the right for the LCD Display to work properly. Please refer to the picture below.
