That rules out the signal strength, both Forward and Return data channels. You didn't mention the SNR, If it is below 35 that MAY be an issue, but it should still work. The signal strengths are in the "sweet spot", so I'd leave things hooked up as they are (unless you remove them temporarily). Even if a TA has been provisioned, you can ask that they be re-provisioned, just like you can do with a Cable Modem that is provisioned, has been working fine, then starts acting up... They can also troubleshoot the TAs remotely, as they communicate in both directions, unlike a cablecard (which they can't view the status of remotely). They can also get a read on what the blinking light means. They also could see that my units were in brick mode (Cox).
