(2)In case of JV300 (COM32 IO PCB)
Connect the negative terminal of the tester to the GND test
pin and measure the resistance by getting the positive terminal
touch to TP with the following.
On the COM32 IO PCB,
TP under CN27 (TP1, 5, 2, 6, 9, 13, 10, 14),
TP under CN28 (TP3, 7, 4, 8, 11, 15, 12, 16),
TP under CN30 (TP17, 21, 18, 22, 25, 29, 26, 30),
TP under CN31 (TP19, 23, 20, 24, 27, 31, 28, 32),
Measured value of each test pin should be in the range of 16K
ohms to 18K ohms.
If all the measured value of the TP is shown in the
abnormal range, compare with the measured value of
the normal circuit board since it may be variation of
the tester.
