It WILL NOT work with the usb disconnected. A TA is simplyt a 2 way splitter with a cable modem connected to the splitter and a usb only data connection.
The pct-vc-5u is a bidirectional unity gain amp to/from the 4 lower ports, the left one allows power to be diplexed instead of using a seperate cable to the power only port. there should be devices or terminating resistors on the other 3 ports
Other than 2 Tivo sets, what's on the other 2 ports?
Are there surge arrestors on the coax? If so, theymay be the problem
However, the VOIP port is a 5 dB loss port in both directions Knowing that, I can estimate the TA's are seeing a +1.5 dBmv downstream level and are doing 42-46 dBmv upstream.
HOWEVER, the modems corrected /uncorrected levels might be high.

Find the common variable...which in this case is the power outlet and power cord. Most likely not the cord unless you can see visual damage on it. That outlet may be frying/shorting out the TAs. Next one you get I would try a different power outlet and swap out the power cord with the new one you get.

No, the one inside should be plugged in there. Its not weather resistant. So the TA starts to work when first setup, but after a few days dies and never returns to life? Have they been connected to the same power outlet for each device that has gone bad?

There is an amplified spliter they installed the last time they was there. Its a box on outside of house. Theres a port for modem which is hooked to modem line. Then i have 4 other lines running to various places. One being my living room, where the tivo is. They have a splitter on that with a rf plugged into the wall to amp the signal. If i take that off, all the tvs in my home go fuzzy.
That isn't a splitter, it's a power injector
What is the exact model # of the amplifier? It should say active return, not passive return
At one time we were told that the TA and the cablecard had to be matched sets... and when calling twc you should use the CM mac address on the TA. It may also be listed in My services
You also cannot get woorking TA's and cablecards from a local office, they must be shipped to you!

Can you describe the splitter?
Are there more than one and how many coax connected devices do you have?
Is the modem on the first 2 way?
It's possible the TA's are at max upstream....
7db of more loss than the modem which is at
|Power Level||46 dBmV||45 dBmV||48 dBmV||48 dBmV|
|Upstream Modulation|| QPSK|
would be 55 dBmv which is too high and might work some of the time and not reliably.
WHAT I WOULD TRY IS TO REMOVE/BYPASS THE 2 WAY SPLITTER THAT FEEDS THE 2 TA'S SO THAT ONLY ONE IS CONNECTED. THAT WILL GIVE YOU 3.5 DB BETTER SIGNAL...
IF IT WORKS, TWC NEEDS TO COME OUT AND INSTAL A 4 PORT ACTIVE RETURN SPLITTER AMPLIFIER.
Nothing I see on the data is due to "Overutilization"
I see a bunch of errors due to TWC not repairing/ maintaining the outside plant- lines and amps on the streets
If a lot of customers have bad/ marginal levels, they slow down the entire node, TWC has been extremely brain dead and has no comprehension of their haphazard conversion from analog ntsc to digital QAM in all areas of the US
So is TWC now blaming the cablecards themselves?
That is a possibility, but I thought the TA's would still go to a steady, not flashing led.
The cablecard with a TA should operate like a cable box and not need telephone calls to reinitialize.
