By swap do you mean you swapped the tv sets around? If that's
what you did, did the known working tv pickup the missing
channels on the cable wire the non working properly tv was just
connected to?

If it did, you likely have an issue with the tuner itself inside
the tv. This might possibly actually be a known firmware issue
and a fix might be available for it. You may want to check with
Toshiba's website concerning your particular model TV concerning
that.

As I read OP's posting he didn't swap the TVs themselves but the
lines feeding each and the symptom stayed with the set; didn't
follow the line. Hence, that does seem to eliminate the input
signal from the candidate pool of issues.

That was also the impression I got, but, I've been wrong before when
making assumptions so, I asked for clarification. [g]

"It's broke!" If there's firmware patch or other more drastic
reset that can fix it, I've no klew or even guess...

Sadly, if it's not a firmware fix, it's new board time if he really
likes the tv.
