Just measured an unloaded tv power transformer of similar size on a kill-a-watt meter, readings were:
122 Volts, 0.26Amps, 9 Watts, 34 VA, 60Hz, 0.28 PF (power factor), so I believe that the PF could be as low as 0.15. 
Did you happen to get a power factor reading?

Here are my Kill-A-Watt Meter readings for my TV's Unloaded Transformer:
123.4 Volts AC
0.40 Amperes
8.2 Watts
50.6 VA
60.0 Hz
PF (Power Factor) 0.16
Hope this helps.
P. S. depending on the time of the day my voltage readings coming out of my outlets can range between 119.8 VAC and 124.5 VAC, when I took my Kill-A-Watt Readings just now my Voltage reading was 123.4 VAC when I took it this morning it was 122.5 VAC.
