SAMPLE SELF CHECK DIAGNOSIS PAGE
2X Blink - Main Power Error
A loss of REG12V from the power supply triggers this protect event. The
usual cause is a failure of the main switching supply. In some instances,
excessive loading on the secondary supply lines can cause the switching
regulator to stop or fail again, if a replacement board is installed.
3X Blink- DC Regulator/Audio Error
The REG 5V and D3.3V source originating on the Main Board is monitored
for low-voltage conditions by the CPU. A failure causing a 3X shutdown
requires replacing the Main Board.
4X Blink – Balancer Error
NOT USED IN THIS MODEL SERIES.
5X Blink - TCON Error/Panel Error
The 5X blink protection mode indicates a communications error with the
timing control circuits (TCON Board) has occurred. If the TCON Board is
available for replacement, replace it, if not, replace the LCD Panel Assembly.
In rare cases a loose or defective LVDS Cable could also be the cause.
