Brake module fuse blown Fanuc R-H

Hello. Does anyone know how to fix this issue?. I replaced fuses F4-F6 in the power input unit but nothing changed. I also replaced the entire power input unit and the problem persist.

Thank you

Well. We fixed it. The problem was the fuse from the power unit. Turned out that the indicator or flag that tells you when the fuse is bad was not on even when the fuse was bad. That made us to get lost.
