Question about Televison & Video

1 Answer

Over air reception

I have an indoor antenna hooked up to my 19" LCD HD TV, and the HD signal is excellent (HD & SD). However, the signal only lasts for 16 minutes -- always 16 minutes, whenever I initally turn the set on. After a while I might get a signal that lasts much longer, but the first time is always 16 minutes. Is this significant? Is the problem with my TV or the signal transmission?

I have used a specially designed HD antenna and an old rabbit ears antenna. Both work equally well (actually, the rabbit ears work a bit better).

    Thank you for your response, digiteyes.



    Unfortunately, I can't hook up my HD TV to an outside antenna, as I live in an apartment building. I live in the New York City area, and I'm not sure where I get my data stream; however, when I do get HD reception, it's perfect -- as good as the HD TV I have hooked to cable.



    My only problem is that the signal usually lasts only about 15-16 minutes, which is a fairly consistent amount of time. If I try a little later, sometimes I get uninterupted reception. What bothers me is the time: 15-16 minutes, which makes me wonder if there's something mechanically wrong.. Strange.

    Thanks for you help.



    I was concerned that the problem might be with my TV; however, it does work fine with component inputs (VHS and DVD), so the problem is probably as you have described.



    Again, thank you. I'll check out your suggestions.

    Can you take your TV to connect it to an outside antenna that is known to perform well with digital reception?



    Where are you located and where are you receiving your signals from?



    p.s. There is no such thing as a specially designed HD antenna... if someone is selling them, claiming that... they are telling you BS. Any antenna that receives SD will receive HD, as they are both on the same data stream.

Unfortunately, I'm in Australia and not familiar with New York TV transmissions, however, the reception principals are the same.

Your signals are most likely bouncing off walls etc in your apartment with several 'reflections' being picked up by your indoor antenna.

This 'multipath' reception causes errors in the digital signals.

Your receiver can correct a certain amount of errors, but if there are too many, your picture will pixelate and the sound will make loud noises and then you will lose reception altogether.

The fix for this problem is connecting to a roof-mounted antenna and signal distribution system. Most apartment buildings have one, however some only distribute cable channels.

There is a possibility of a fault with your TV, but from what you describe, it sounds like a signal issue.

Have a chat to your building manager and ask what system they use for FTA reception in your building.. perhaps there's a fault that they are not aware of.

Sorry I can't be of more help.

Good luck.

Antenna hook up


If you are using an indoor Antenna:
1- the most probable reason would be the location of the antenna and TV in an area where the reception is very low. Indoors all houses are affected by the running electrical circuits which in turn generate magnetic field that together with the structure of the house obstruct or weaken the wave signals of wireless and TV reception. Also this issue may be aggravated by the vicinity you are live in. Where you are living may not have the optimum reception from some services including TV signals. Your best bet is to try moving the (Indoor) antenna closer to the outside (such as windows, or better to a balcony) and try all four directions of the house.
2- One other possibility, is the antenna jack being disconnected from one of its wires (or a de-solder) at an internal part of its circuit). This problem can be detected by trying another antenna that is working good when used with another TV (and preferably at a different location) thus testing for the possible weak signal at the same time.
3- The last possible issue is the antenna receptacle built onto the Tv set. This may have a problem of some element of it disconnected internally on the board or de-soldered..
If the Antenna is external, all the above points are still valid, but the probability is higher, for some hidden disconnection on the receptacle, the antenna plug or at the connection of the co-axial cable with the external antenna. (Once I found a co-axial cable with disconnections of its central copper wire within the protective insulating coat- probably due to defects in the plastic coat that had microscopic holes that allowed air and humidity into the central wire and caused it to corrode and have those discontinuities)..

I just purchased an indoor antenna for to view local stations. Can i use an indoor antenna for my olevia 232-t11 lcd-hdtv? If I can, what steps do I need to follow?


Yes you can use an indoor antenna. Just make sure it is an HD antenna to get the digital channels clearly. You will have to do a scan to pick up local channels. In the TV menu, it will ask you if you want to scan for "cable" channels or "antenna" channels. You want to choose antenna.

PICTURE SEEMS TO BE BLURRED WHEN ITEMS MOVE FAST ON SCREEN, ESPECIALLY PERSONS IN CLOSE UP.


The Sony Bravia KDL-32BX320 generally gets excellent reviews (4.5 stars out of 5) from owners, so I have to wonder what you're watching.

This is an HDTV and should excel when provided an HD signal to display. SD (standard definition) signals often look worse on an HD display than on an SD display. An HD signal is only available via the following ways (reference the image below):9_27_2011_4_28_11_pm.jpg
1) An "over the air" (UHF / VHF) antenna is connected to the cable / antenna input and there is a broadcaster of HD content nearby (only an over the air antenna can input HD signals to this jack - no cable boxes, etc.).

2) An HD Cable TV, DirecTV or Dish Satellite set top converter, Blu Ray Disk Player (or other HD source is connected via HDMI or Component RGB jacks.

3) An HD video played back from a computer hard drive connected to the VGA jack (when the computer is equipped with a modern processor and video card).


You will NOT be able to view HD video if:

1) The source material is a SD (non-HD) source. An over the air antenna will not provide HD signals if the broadcaster does not have HD content to show or is not capable of broadcasting in HD. Digital is not necessarily HD.

2) The source material (other than over the air antenna) is connected via Antenna / Cable jack.

3) The source material is connected via Composite jacks.

The USB jack is generally not an input for motion pictures, but may display stills - depending on the TV's ability to play the format they are stored in (jpeg, gif, bmp etc.).

Hopefully, this will help you solve the problem you're having with the picture. Good luck!

HDTV unable to get HD Channels w/ Antenna


The problem could be your antenna. Many people will buy small indoor tv antennas and wonder why they're not getting the signal that they want or the channels that they expect. Its not your fault. Digital signal is in two formats: UHF AND VHF. Some antennas only receive UHF. But many of the low band channels are VHF, so 1) you need an antenna that will receive those signals and 2) you need to know how and where to install that antenna and 3) you need to know if you need a signal amplifier depending on your coaxial cable length and number of connections. I recommend visiting dennys antenna service (no I don't work there and I have never purchased anything from that website. He just has an excellent informational article with a great deal of "how to" on his pages.). http://www.dennysantennaservice.com/2029710.html This should be of great help to you. Happy viewing =)

I hooked an antenna up and can't get a picyure!


I assume you have tried to retune the TV & angle the antenna in different positions. Very often, due to the location of your home & the strength of signal in that area, you usually find that , no matter what you try, an indoor antenna is just not strong enough to pick up in a weak reception area. The only alternative is to try & add a signal booster onto it or much better still ( and a lot less future reception problems) is to rig up an outdoor antenna.

I don't know in what area you live & therefore how strong your reception area will be, but as a general rule an indoor antenna is never the best type of aerial to have to receive digital signals, you will always find that you pick up some good strong channels but more often the rest of the channels will be poor or non-existant & will constantly break-up/freeze etc. The best advice would be to try & fit an outdoor antenna if possible.

I've just hooked up my converter box. I can get most channels with decent reception. However, I can't get my NBC affiliate. I've been told that I need a new indoor directional antenna. What kind shoul


Totally depends on how far you live from the station you want. I sell antennas, converter boxes, the whole shebang at my retail store, and you're not alone in your confusion :-) My best advice to you is this:

www.antennaweb.org

If you live closer than 15 miles, rabbit ears
If you live closer than 20 miles, omnidirectional
If you live closer than 50 miles, midrange outdoor (oldschool arial w/ rotator)
Further than 80 miles, you'll need a long range with rotator, perhaps even an amplifier to go with it. Print off what your results were on antenna web and bring it to a RadioShack or a local antenna store and they should be able to point you to the right antenna for your particular location.

IS MY TV DIGITAL?


yes you will. either install an outside antenna or get a good amplified indoor antenna. try your old antenna first, but when your picture freezes or it says something like " weak signal " you will need that new antenna

Just the one TV freezes


hello, it possible if your sharing the signal to sometimes loose reception you should have a dedicated hdtv antena or hdtv cable service for your main tv.
you can check by removing all the other sets and see,
if it happens again then you need a dedicated hd antenna or signal. this should be better for you and your hdtv reception.

Digital to Analog converter...no signal


One of the problems with digital reception is if the signal is not strong enough for the converter box/or built in tuner on a new TV- you will not get any picture at all. If you followed all the directions-and the converter box shows no channels- then you do need a better antenna. I don't know how far you are from the broadcast antenna, but a good rule of thumb is if you live 10 miles away, buy an antenna that is good for twice that distance, or further. They are rated in miles of reception
