Troubleshooting 4 Blinks Error Code
The voltage generated by the power supply are monitored by IC701. If there is an increase in
voltage, IC701 outputs a high to the DA board.
Primarily the P board causes 4 blinks, followed by the DA board.
To troubleshoot a 4 blinks condition, measure the voltage at pin 18 of connector DA6 in the DA
board. If the voltage goes high, the P board is the problem. If the voltage stays low, then the A
board is the problem.
P
– 95% Probability,
DA
– 50%
