Samsung DTB-H260F ATSC tuner - Page 113

post #3361 of 3649
Whew! I could barely read that, for sure could not say it, how did you ever type it all out?
post #3362 of 3649
I also have to start up my receiver (Onkyo 705) before I turn on the Samsung tuner. Otherwise, I get picture but no sound.

UPDATE:
My Samsung H260F is now 2 years old. I got one of the first shipments at my Circuit City. Too bad the stores haven't lasted as long as my H260F. I have left it on almost continuously for the past 2 years since it takes 12 seconds for it to come on. It has performed very well and is rock solid. I recently purcahsed a CM 7000 even though it is not HD it comes close with SVideo hook up on my Toshiba HDTV. I am starting to use the CM7000 more since it can get more stations, has quicker channel changes and quicker guide and still locks into all the stations.

My ideal tuner would be a Samsung that has the latest HD tuner chip, quick on time, quick channel changes, quick program guide and DVR capability for about $150. Then I would get rid of all the clutter on my video console with one box.

Is there anything better? My venerable Sony VPL-VW10HT projector would like to know.
post #3365 of 3649
For doing an HD signal - probably not. For doing an SD signal - the better recomended CECBs (Zenith,Insignia) might pull in a signal when the Samsung won't, but they will not display HDTV.
post #3366 of 3649
As far as *better*, there are HD tuners with better PQ (like the Sony DVR's, LG tuners and DVR's, and the Hisense/USDTV db2010), but not really reception-wise.
post #3367 of 3649
My best tuner is the zenith converter. But only low def.
Next is the DTV pal dvr which has reboots and bugs but still works well.
The Samsung 260F is below these.
Then far down the list is my LG 3420A that has lots of trouble with my multipath but the tuner is sensitive.

When there is a good HD tuner that matches the Zenith converter I want to get it yesterday, but I want a DVR with outputs like my old LG also. Otherwise I am forced to keep using it some.
post #3368 of 3649
Wrt this discussion of the sensitivity of the Samsung tuner, how does it compare to the current crop of tuners contained in LCD/plasma televisions? Is it very much brand dependent or do most television manufacturers source their tuners from one or two vendors? But even so, in most cases wouldn't upgrading one's OTA antenna be the most effective means of improving reception? For me it is not clear how much of signal reception is courtesy of the antenna, tuner (or the cabling in-between for that matter). I've check other threads where folks swap out tuners and get different results. But I suspect these are with stations that are on the edge, and the reception gained might be very tenuous.

One would think so, but not always. I have the DTB-H260F hooked up to a mammoth ChannelMaster 3671 on the roof. It doesn't do as well as my Zenith DTT900 CECB hooked up to an indoor silver sensor.

Some of the TVs seem to have outputs. Can they be used as tuners as well?

But unless you swap the Zenith and the DTB-H260F you won't know where to give credit for the improved reception, no?

Well, I spoke too soon.

In the last two days I have had almost zero success in getting the system to power on and do the HDMI handshake.

I have lost channel 13. Simultaneously, the tuner added all the channel 18-n and 44-n. Why it adds channel previously deleted is unknown to me. Why it drops channels I have programmed in, is similarly unknown to me.

Best place to ask about the HDMI is go to the Digital Video & Audio page.

As for lost channel I have the same problem from time to time, As I am in middle of 4 different market with me in middle of a X. With one market in northwest and the other in southeast each has a Digital RF19 and it a battle with the 2 loose one and gain the other back when I move the antenna or I loose both as they battle for the RF19. As for new channel poping up most likely it a trop I once pick up a PBS channel with 7 sub-channel and it took away from one other progamed channel and I look up it in FCC database and it was from Carbondale, IL and then look up the map it was 333 miles away I had it for about hour. You going to have with any tuners if there a strong trop siginal if if it right it will override your program list and it may go away when the trop channel loose and you may get the other channel back.

The outputs on some digital TV can feed something like a VCR or DVD recorder but the TV needs to be ON and tuned to the channel you'd want to record. It also outputs things like the TVs OSD, so you don't want to be adjusting the volume when recording otherwise you'll record the volume OSD.
post #3375 of 3649
I was sitting watching the TV this morning, channel 28 and all its sub-channel just disappeared. I was watching a program and it just disappeared! The Tuner went to the next higher channel - from 28-4 up to 30-1. This was preceded by the complete loss of channel 13 two days before.

Signal strength on these channels is typically quite strong (80% or more of full scale).

I went into the Channel Manager to see if they had been deted by the computer (deleted by a computer glitch). Neither is even listed.

My new Dish VIP722 DVR has an excellent and sensitive OTA tuner, that I can personally say from experience, is better than the Sammy.

post #3379 of 3649
This too has been happening to me as well. Use my 260 as QAM tuner with a Samsung HDTV (san QAM). One day all the channels of the NBC affiliate (3-1, 3-2, 3-3) are there
then suddenly gone. Has happened to other channels as well. Insight Cable re maps
the channels to there analog OTA (3 (NBC), 11(ABC), 32(CBS), 41(FOX) etc. Tried a rescan and still can't see 3-1(NBC) or the affiliate's other sub channel 3-3, only one
260 can find is 3-3 (weather service channel). Any thoughts?

Hello,

I have a DTB-H260F digital set top box. I subscribe to Time Warner cable and have the basic program that doesn't require a box. When I hook up the cable to my TV and run a scan I get over 78 channels. When I take this same cable and hook it up to my DTB-H260F I am only getting about 20 channels. What is wrong and how do I take care of this so I get the same amount of channels?

Make sure that have it set to scan Cable and not ATSC? Other than that I wouldn't know what else it could be.
post #3382 of 3649
yes when I did the scan I said to scan cable

I've been using mine constantly now that I've cancelled cable and rely on OTA ATSC exclusively. At least once a week the thing will crash. I'll be changing channels when suddenly the TV loses all signal from the box. Then the box cames back up but no channels will tune in. I have to power cycle and then everything is back to normal.

Keep in mind that many of the "basic" ch's on cable are analog ch's and the H260f is a digital only tuner.
It is completely blind to any analog ch's (generally ch's 1 thru 69 are analog).

It will pass the analogs via it's RF/coax out, but it cannot tune them.

My guess is that 58 ch's are analog and 20 ch's are digital on your cable co's "basic" system.
post #3385 of 3649
I will have to check about the analog ch issue. When I run auto tunning it comes up with 250 channesl but when I scrole through them I can only see about 20 channels.

Your cable system carries both analog and digital channels. Your television only tunes in and adds the analog channels.

The Samsung box only knows about digital channels. The Samsung box will add all digital channels, whether they are encrypted or not. The people who made the box should have had a flag to block out encrypted channels as there's no point in adding an encrypted channel. Even though there are 250 digital channels on your cable system, only 20 are clearQAM which you can see.

I just called Time Warner Cable and they stated that the basic package is currently Analog but as of June they will be going to Digital. Looks like I will have to run my program scan again in June. Thanks for all the help.

TWC CSR's are known to be goofy and seldom understand their own systems. Try asking that same CSR about QAM ch's.

This may be accurate info, but I'm highly skeptical of it for two reasons:
1. I believe all cable co's are federally mandated to carry basic ch's in analog till 2012? 2014? Something like that.
2. If they do go "all digital" then they must provide cable box's (converters) for any/all customers on any/all analog TV's in their home free of charge.

I hope you received accurate info, but I wouldn't count on it.

No! Re-read WhiteWhiskers' post.

You said you get about 20 channels - are you able to watch any channels on the Samsung? Are they HD? If so, you will most likely not get any additional channels in June. Most cable companies only provide the local channels in clear QAM. The Samsung box will not decrypt the other channels for you. If that's what you're looking for you will need to rent a set top box from the cable company.

Uh huh.

rick12667: So, assuming your TWC CSR gave you accurate info (which I still seriously doubt) TWC is not going to put all 78 digital ch's in the "clear". Chances are your current 20 QAM ch's in the clear will probably be the same 20 ch's in the clear any time in the future. No more, no less.
