8.4 TROUBLESHOOTING - ERROR 04B0

ERROR CODE 04B0

1) SYMPTOM:

04B0 – LCB communication disconnected.

2) SOLUTION:

1) If the display is giving a 04B0 error, check the LCB LED10 status.

- LED10 blinking: Turn off power and after 3 seconds, turn on power again. If the console shows the 04A0 error, skip to Step 2.

- LED10 off: Check the connection of the digital communication wire at the UCB and LCB (Figure A & B). If the connection is good, replace the digital communication wire.

2) If LEDs 7 / 8 / 9 / 10 blinking together, this should be LCB software problem. Re-install LCB software. If this does not resolve the issue, replace the LCB.
