Short answer, if TPC is enabled, then Yes it will affect the other APs and cause problems.
Have you done a wireless survey before installing the APs?

If TPC is enabled, what have you set as Power Threshold and Minimum / Maximum Power Level Assignment?
Do not change those settings before reading about what they do.

Hi I am not where I can look at the TPC setting, it would be what is set out of the box.

 

There was a certification performed, the 5ghz was fine but some areas the 2.4 was out of -67 scope.

 

So the controller does not differentiate if power is manually set or global it will adjust the globally set access points as needed

Do you use voice over Wi-Fi services? Otherwise -67 is not really required for a stable signal. But I suggest to have at least -72 dBi at the outer regions of a cell where a person should have a good signal.

You find the TPC settings on the WLC under Wireless - 802.11b/g/n (or a/n/ac) - RRM - TPC.
What are your current settings there?
