IGT PE+ Poker: Constant “Door Open” State (Suspect Bad LED)

Before removing the processor board, check the following areas:

• Check self test inputs to verify problem (door open)
• Check the bill acceptor for a door open signal
• Check optic alignment (door LED to phototransistor on chassis)
• Visually inspect wires and connectors
• Use a flashlight to activate the phototransistor, if it works replace the LED
• If the phototransistor is not activated by the flashlight, then replace it
• Disconnect door LED at J/P 170 and test for 5 VDC
• Disconnect the phototransistor chassis at J/P 171 and test for 8 to 9 VDC

If that doesn’t work, try the following steps:

• Replace the processor board with a “known good” one
• If the processor board seems bad, check eBay for replacement or repair service
• If the processor board is good, then replace the motherboard
• To repair the motherboard, use this diagram to isolate the bad trace
• If the motherboard and processor board are good, then use this diagram to test for wire continuity
