ATSC Tuners In HDTVs (see Samsung Poll) - Page 53 - Canadian TV, Computing and Home Theatre Forums

I have a Samsung LN46C530F1F that will not tune into Ottawa OMNI1, channel 60.1 (real channel 27) no matter what I've tried.

On the other hand, the 19" Philips TV in the kitchen has no problem with it. Even removing the splitter or using a distribution amp, the Sammy still can't find it during autoscan or tune to it manually.

Don't know how Samsung models are related, but my 4-year old Samsung plasma, PN42B450, is quite a bit poorer in receiving stations than my 1-year old Visio 21-inch, using the same feed.

Wow...maybe bad PSIP?

My newer Samsung (from last year) has had no real trouble with bad PSIP - in my case, Global 11.1 from Sherbrooke. It wouldn't find it on autoscan, but if you punched in 11 on the TV, it would find it. Looked at the PSIP on the PC, and it wasn't pretty, but the TV managed. I think it has since been fixed, but this is at my cottage, so I haven't checked since the fall.

Maybe since it's older, it doesn't handle errors as well?

Check with Samsung to see if there is a firmware upgrade. As cptmds suggested it might be that the TV doesn't like CFMT's PSIP.

MaxHeadroom · 2012-05-09, 11:23 AM

Upgraded firmware last night to no effect. What's weird is that it did pick it up when I had my antenna at grade with weak signal, but you'd think that with the antenna on the roof it wouldn't be any worse.

I read somewhere else that a hard reset of the TV might help. I'll try that next.

Dr.Dave · 2012-05-09, 11:39 AM

MaxHeadroom, maybe you have a strong adjacent channel overpowering a weak one and the Samsung isn't as capable in rejecting the interference. You may be able to adjust the antenna to minimize the strong signal and/or maximize the weak signal. My Samsung has a signal quality meter that I used to adjust my antenna

I'd contact the TV station's tower engineer and let them know. Sometimes the problem is at their end.

levibluewa · 2012-05-09, 04:30 PM

I bought one and it went back. Traded it in for a Sony. The Sammy wouldn't find all the QAM channels that all the other sets in the house found.

Digital tuners are fickle, period. Recently the Sony tuners won't find channels if you "Add Digital Channels", but if you enter the # ... the tuner pauses and tunes the channel...then when you return to "show-hide" the sub-set of channels are listed.

Sometimes the OTA channels disappear. On one occasion the local channel had to do a reboot of their PSIP computer and the channel returned.

Good luck

This is one aspect of ATSC I REALLY hate: the channel mapping! Actual vs virtual channels? And if either number changes as it happened during the transition, your TV might not pick it up? And when you do find it, you might end up with two identical virtual channel numbers? (happened to me in Montreal)

Honestly, it was easier during the Seventies when I simply turned the freakin' dial!

roger1818 · 2012-05-15, 02:06 PM

^^^Yes, that does make things confusing for people. We are still in the state of transition however. In the long run things should stabilize and changes should be rare.

Francois Caron · 2012-05-16, 01:33 PM

That could be as simple as listing both channels when you're going through the configuration list. I don't mind seeing just the virtual channels when watching TV, but I do need the physical channel numbers as a reference when I'm setting them up using the tvfool.com data, and occasionally need to eliminate duplicate channels. Displaying the channel's encoding would also help (QAM and such).

We're almost there! Despite not showing the physical channels on either set, my $200 19" Sharp LCD TV has a much simpler interface than the one on my $900 40" Sharp LED TV, and it's much better at displaying relevant program information on demand!

I'll have to check the Samsung sets out as well. In the stores, they do look amazing once you turn off the Torch mode, and most manufacturers are now pumping out affordable $200 20" LED sets as well! They make my two year old 19" LCD set look like crap!

Just need to sneak a TV antenna in the store.

I am on the latest firmware for both Samsungs. I heard newest Samsung tuners work and would appreciate if anyone can confirm with the model number. Samsung tuners are otherwise very fast and they show info and guide (12 hr).

I can confirm another Samsung TV, Model LN40A530P1FXZA
which doesn't display anything on TVO. Anyone with a Samsung successfully
receive TVO's EPG?

Agree it's a shame, as other than the TVO issue it's EPG is the best I've seen yet.

jihenry · 2012-05-20, 12:28 PM

My Samsung (UN46C6300) works fine with TVO EPG.

majortom · 2012-05-20, 01:07 PM

jihenry, what's the manufacture date? the one I highlighted says July 2008.

jihenry · 2012-05-20, 04:37 PM

Samsung UN46C6300 is a 2010 model (D is 2011, E is 2012 etc.) so perhaps the newer models don't have a problem with TVO EPG.
