Is my TV stupid...or am I?

[MinisterofDOOM]

I have a new-ish Dynex 32'' HDTV. It has a built-in digital tuner. The tuner supports the established digital format and decimal channels. BUT...it refuses to find a bunch of channels I know I get. For instance, I can go in the next room and turn on the nicer Sony HDTV and tune to 84.32 for History's widescreen EDTV broadcast (480p). Walk back in my room, punch up the same number, and the TV says "Channel not found." The channel IS THERE. Another odd thing is, the TV "sees" channels at 84.2, 84.3, 84.4...but when you tune to those, there's nothing actually being broadcast. And the hundredths-resolution isn't the problem, either...the TV sees 84.11 (again, though, there's not really anything broadcast there).

I've set the damn thing to scan for channels multiple times. I've even gone into the list of channels the TV has detected to see if it was "disabled" but it's not there to enable. I can't figure out why the hell it won't find all my channels. Anyone have any idea what the problem might be? I'm thinking it's probably just because it's a cheap POS. I may borrow someone's external digital tuner to see if IT will find those channels.

I may have some idea what's going on, I had sort of the same problem. One of my coworkers used to work for a cable company and helped me, maybe we can help you. First, what's the model number? And how do you have it hooked up? Just cable line to TV, or through a cable box?

Not all tuners are created equal.

One problem is that the signal strength to your room might not be strong enough to allow the TV to display the channel properly. Hell I've seen this happen with 2 TV's in the same room before.

Also, have you done the TV auto channel find? Sometimes TV's cannot show a channel they have not "found."

It is a Dynex L321-10A.

No cable box...but there is a splitter between the wall and the TV. Splitter also goes to my cable modem. I'll try running directly to the TV and see if that makes a difference.

Yeah, I've run the auto-find several times. No luck there.

Odd thing is the Sony TV that does get these channels is connected via ~30'' of cable running the length of the apartment. If not for the splitter, I'd expect it to have signal strength problems long before my TV.
