Why this happens
Potential causes include issues with either the main PCB or control board, problems with the sub PCB or display board, damage or looseness in the wire harness connecting these boards, or harm to the flat wire linking them.
How to fix it
If unplugging and restarting doesn't fix it, the internal wiring or a control board may need attention. This one needs a professional technician.
