How to do Self-Diagnosis
The voltage should be within the range of
4.5V~1.0V between MAIN PCB CN30 #3
and #9.
The voltage should be within the range of
4.5V~1.0V between MAIN PCB CN30 #7
and #9.
The voltage should be within the range of
4.5V~1.0V between MAIN PCB CN30 #4
and #9.
The voltage should be within the range of
4.5V~1.0V between MAIN PCB CN30 #10
and #9.
The voltage should be within the range of
4.5V~1.0V between MAIN PCB CN30 #11
and #12.
The voltage should be within the range of
4.5V~1.0V between MAIN PCB CN51
#13 and #14.
The voltage should be 7V~12V
between MAIN PCB CN74 GRAY
and BLUE.
The voltage should be 7V~12V
between MAIN PCB CN74 GRAY
and GREEN.
The voltage should be 7V~12V
between MAIN PCB CN74 GRAY
and YELLOW.

It needs a Oscilloscope to do the error
check. So, it is more realistic checking
the error after replacing Main or Panel
PCB.
