I just checked and it's OK now ( Friday night just before 11:30 PM PDT),
showing
a _Friends_ rerun on 5-1; same on 5-2 but with sound track in Spanish.
Looked like
the same number of signal bars as usual. Where are you located? Here in
San Diego
I get co-channel interference to KNBC-DT from a low-power analog translator
on
the same channel, Channel 36; you could be having a related problem on
Channel 31
from a LP transmitter in Victorville, Twentynine Palms or Palm Springs.

There are two steps to check the above possibility:

First, connect your antenna to a UHF TV tuner input and check whether an
analog signal
is presently being received to interfere with KTLA-DT.

Two, this link to the FCC will let you research your interference if step
one is a "Yes."

http://www.fcc.gov/mb/video/tvq.html

Enter "California"; Upper and Lower Channel = 31; Click "Submit data"

You get about fourteen returns, most of them NOT in SoCal. Click each
possibility
and analyze the results for location and antenna pattern of the interfering
signal. If
the source is not in a direct line between you and Mt. Wilson, you can null
the
interference with antenna tricks. (I am combining two identical antennas
exactly a
half-wavelength apart, since my interference comes straight from one side;
depending
on the angle of arrival of your interference, you'd need to separate the
antennas by
more and it requires calculations or trial-and-error.)

Enough of that -- we don't even know if you have an actual interference
problem.

Write back.
