When charging camera, shows amber light flashing rapidly. Is it a battery or camera issue?

When I went to charge the 6th camera in my set, the orange amber light would flash rapidly for 3 seconds. When I looked this code up, it stated that the battery isn’t charging and the it might be connected to the wrong adapter. The two chargers I got charge the other 5 just fine, but not this one. Thinking it was the battery I went and bought another battery. Put that in and gives me the same 3 second rapid orange amber flashing. I have 3 different adapters and two batteries to no avail. So now I’m thinking it’s the camera itself but with it being over a year old, I’m sure it’s not covered u see warranty anymore. Any thoughts or ideas to get the 6th camera working.
