Base station VMB4540r3 not recording

[trmcl530]

base station VMB4540r3 not recording since 30 Jan 2024. Base station continually blinks yellow. Have restarted it multiple times, reset it multiple times. Blue light comes on briefly then goes back to yellow blinking. Does not have card. Can view live footage on all 5 cameras and doorbell.

It may be that there's a poor signal to one or more cameras:
