FANUC Controller Oi-Mate-TD

[M.RISHIKESH]

Dear Experts

We are facing an issue of Display not getting ON in FANUC Controller Oi-Mate-TD, Type: A02B-0321-B530 .
Found 24VDC is OK at input connector CP1 to Controller and “8” appearing on CNC .

· We have tried by disconnecting all connectors except CP1, also
· We have tried switching on by pressing soft keys 1&2 and 1&7 together Still same issue of display not getting on
· Fans are in working state

Request for advice

Regards

If the "8" is solid:
"State where the cpu is not started after power is turned on"
-the mainboard may be faulty
Back up need it if you wanna mess with the mainboard,otherwise will be lost due to manipulating the FROM/SRAM module.
Better call Fanuc India for this kind of job.
Good luck
