+3.3 VDC Power FIP
Step Check Yes No
Possible causative parts:
• Top Harness Assembly (PL18.2.5)
• AC Inlet (PL18.1.31)
• LVPS (PL18.1.34)
• MCU Board (PL18.1.13)
1 Check the connections between the LVPS and the MCU
Board
Check the connection between the LVPS and the MCU Board.
Are P/J501 and P/J29 connected securely?
Go to step 2. Reconnect
P/J501 and P/J29
securely.
2 Check the continuity between the LVPS and the MCU Board
Is each cable of P/J501<=>P/J29 continuous?
Go to step 3. Replace the Top
Harness
Assembly.
3 Check the power from the LVPS (+5 VDC)
Check if the voltage between the LVPS ground and the
P/J501-5 pin is about +3.3 VDC.
Replace the MCU
Board.
Go to step 4.
4Check the power (off/on)
Turn the power off, wait a while, and turn the power on
again.
Does the error still occur?
Go to step 5. Finished.
5 Check the AC power to the LVPS
Is the voltage between the P/J48-1 pin and the P/J48-3 pin
of the LVPS 100 VAC?
Replace the LVPS. Replace the AC
Inlet.
