Testing the Printed Circuit Boards (PCBs)
1.
Check for voltage to Power Supply Board.
•
Set the probes of a DC voltmeter across test points TP1 and TP2 (see Figure 22).
•
Check for 5 VDC
±
0.25V.
•
If voltage does not check out, check for F102 fuse blown. Also check that the jumpers are properly
configured.
•
If voltage still does not check out, replace the board.
2.
Check for power to the Display/Control Board.
•
Set the probes of a DC voltmeter across test points TP1 and TP2 (see Figure 23).
•
Check for 5 VDC
±
0.25V.
•
If voltage does not check out, replace the cable.
•
If voltage does check out, but board does not function, replace the board.
