Vxd-r70 & evx-r70 help!

Hello group, So I have a VXD-R70 repeater that I am trying to get working. It powers on and I can read/write the code plug. But when it powers on only the “power” light illuminates and it does not repeat. Can anyone help me with this?

On the EVX-R70 I replaced the connector board and the repeater board on this unit and can no read/write the code plug but again, I only get the power light to illuminate and the repeat function does not work. Seems like I am doing something wrong here.
Can someone please help?! Thank you!!
