Newer television sets employing hd or digital require good antenna signal strength to allow the sound to come on.

there is an auto muting device built into the set so as if the picture is at all snowy it will mute the sound.
what you can do however with this set is to enter service mode and there is an option that you can change that will disable this muting aspect of the television.
The reason why a lot of sets have this option is to prevent damage to speakers.

I bought the same TV wich is in fact a Seiki TV, see the warranty paper. The television has digital and analog tuners so is able to receive digital channels.Our television receive signal thru a rabbit ear antenna and we had some trouble to scan all the digital channels. We had to change the orientation of the antenna to receive correctly the signals and we had to scan many times. We finally conected the TV to a roof antenna so we where able to scan all the channels of Montreal, north Vermont and north New York areas since we are living in the south shore in front of Montreal. After the scan was completed we conected back the TV to the rabbit ear antenna and the television is working correctly receiving all the stations of Montreal area with a very good picture quality.

I live in Victoria Tx. I can not afford cable or dish. I am able to recieve all 4 of the the number 25 channels. Why am I not able to recieve any of the three number 19 channes. All 19 and 25...


Channel 19 actually broadcasts on VHF channel 11 (approximately 201MHZ) and channel 25 actually broadcasts on UHF channel 15 (approximately 479MHZ). I know that sounds a bit weird but it has been done so that stations don't have to change there "call" channel number when we switched to Digital TV. Your digital converter box keeps track of this. This is important to understand because you need and antenna that is good at picking up both UHF and VHF signals. If you're not getting channel 19 it may be due to a poor VHF portion of your antenna. If your using a basic old set of rabbit ears for your antenna that has a loop in the middle then I might have a trick for you. Most rabbit ears have 2 telescopic antenna elements. Extend or collapse until each length is 14.7 inches long. (Which is a quarter wavelength at 201MHZ). You are effectively tuning (Optimizing) your antenna specifically for that channel 19. You may need to rotate your antenna a bit to find the best signal.

There are other factors which can hinder you receiving channel 19 but this is a good starting point. Let me know what type of antenna you have. Hope this helps.

HOW TO HOOK UP A ANTENNAE


Hi there,

Well you can follow the below steps -
1. Inspect the antenna for any signs of damage. Identify and examine the power adapter cord and the coaxial antenna cable for any rips tears or other defects.
2. Plug the adapter into the antenna's power adapter socket. It will be labeled "12V DC/Adapter". If you are using an antenna that does not require power, such as rabbit ears, you may skip this step.
3. Next connect the antenna cable to the television using the TV's "Antenna In/75 Ohm" input jack. Make sure the antenna connector is twisted tightly into place. Place the antenna on a sturdy surface such as the top of an entertainment center. If you have an older analog TV that is a non high definition ready/capable display and are using a digital to analog converter box, generally, the antenna will plug into the input of the converter and the output of the converter will plug into the antenna input of your TV. 
4. Plug the antenna's power supply into a 120V AC wall outlet. This will turn the antenna on. If you are using the "rabbit ears" style antenna, make sure that the each section of the antenna is fully extended. This will give you the best reception.
5. Turn on the TV and check for digital reception. You will know that you are receiving digital signals because the picture will be clear and free of any analog "snow" or other artifacts. Digital TV channels have DVD quality picture and sound.

TV picture freezing


digital signals do not fade out and get snowy like signals used to do ... if the signal gets too weak then it just freezes .. you might say its either perfect or frozen .. sometimes it gets blocky .. where some sections of the screen freeze while other sections continue .. what that means if you are using an antenna is .. you need a better antenna or better aim for the one you have .. outside is much better than inside but just rabbit ears are ok for strong signal areas .. you can aim the antenna based on a signal strength meter usually provided in HD receivers in the setup menu .. you can also get an antenna map from "www.antennaweb.org" .. that will show you what direction to point the thing for each channel and how strong each channel should be ... if you are using Cable instead of an antenna then you should have good signal strength but there is a problem called "Crest Factor" .. that becomes an issue when they put too many signals on a given cable .. the cable handles it ok as long as there is no damage (bad ends, water inside, animal chews, corrosion) but the cable box or receiver may be overloaded as thousands of signals drift in and out of phase ... thats a cable company problem that might be getting worse as more channels are added .. the results are that periodically the picture will freeze or pixelate .. you probably have to accept a little of that but more than a little gets really irritating ....off the air reception with an inside antenna (like rabbit ears) you will find that moving around the room can effect the signal for channels in the UHF range (most are) .. aiming the antenna and getting it as high as possible will minimize that problem.. make sure whatever antenna you use is designed for UHF as well as VHF .. the little circle often found between the two "rabbit ears" is actually the UHF part of the antenna .. it can be rotated for UHF channels while the big ears are aimed and adjusted for VHF .. antennaweb.org will tell you which is UHF and VHF ..

TV freezes up when turned to channel 33-1


I had the same problem. I also use rabbit ear antenna , no cable or satellite. I was watching ch. 33.1 and the tv turned off by itself. The remote wouldn't work. The power on/off buttons on the side of the tv wouldn't work. I had to un-plug the power cord to turn the tv off. The tv forze on ch. 33.1 when I turned it back on.

I called Vizio, they told me they received hundreds of complaints from people in Texas complain g about these problems.

I was told to un-plug the antenna cable and re-plug it. I did this plus I re-scanned all channels. The problem has been solved, the channel (33.1) no longer freezes and the tv doesn't turn off by itself.

Hope this helps.

I get no stations on my tv


Use an Antenna that Provides Good Reception of All Channels
  • Most existing antennas used by consumers will provide good reception of DTV signals. (Before making any changes, try your existing antenna first to see of it allows you to receive all the stations you normally watch.)
  • For watching DTV signals, you will need an antenna that provides good reception of both VHF signals (channels 2-13) and UHF signals (channels 14-51) to reliably receive all of the digital signals broadcast in your area.
  • Many antennas are designed only for reception of either VHF or UHF signals (but not both). For example, the commonly used “rabbit ears” indoor antenna is only suitable for receiving VHF signals. To receive UHF signals, an indoor antenna should also include a wire loop or other feature for reception in that band.
  • The reception capabilities of TV antennas also vary considerably, so be sure to talk to retail consultants and look at information on the packaging and/or the Internet to make sure that any new antenna you may choose provides good reception of both VHF and UHF channels. In addition, if you use an indoor antenna and receive signals on VHF channels, you may need to use an antenna with amplification.
  • Many antennas currently being sold as “HDTV Antennas,” perform best at receiving UHF signals; some of these models state that they provide reception of signals on channels 7-13 but actually perform less well receiving those channels. If you obtain one of these antennas, be sure it provides good reception of all the VHF channels as well as the UHF channels.
  • To check for the DTV signals that are available at your location, use the DTV Reception Maps available at www.fcc.gov/mb/engineering/maps.
Check Your Connections
  • Check that your digital-to-analog converter box or digital television is connected properly. Make sure your antenna is connected to the antenna input of your digital-to-analog converter box or digital television. If using a digital-to-analog converter box, also ensure that the antenna output of your converter box is connected to the antenna input of your analog TV. Refer to the owner’s manuals of your components if you are unsure of the proper connections.
  • Ensure that your components are plugged in and have their power turned on.
  • If you have a digital-to-analog converter box, tune your analog TV to channel 3. You should see a set-up menu or picture displayed on your TV screen. If you do not see a set-up menu or picture, tune your TV to channel 4. If you still do not see a set-up menu or picture, recheck your connections.
Perform a Channel Scan
  • Digital-to-analog converter boxes and digital televisions have a button, usually on the remote control, that is labeled “set-up” or “menu” or some similar term. Press that button to access the set-up menu. Using the directional arrow buttons on your remote, scroll to the option that allows you to perform a “channel scan.” The channel scan will automatically search for digital broadcast channels that are available in your area. Consult the owner’s manual of your digital-to-analog converter box or digital television for detailed instructions on how to perform a channel scan for your device.
  • Once the channel scan is complete, you will be able to tune to the digital channels received by your antenna. You should perform a channel scan periodically to check whether additional digital channels have become available.
Adjust Your Antenna
  • Small adjustments to your antenna can make a big difference in the number of digital channels you can receive. If you have an indoor antenna, try elevating it and moving it closer to an exterior wall of your home. After adjusting your antenna, perform another channel scan to see if your reception is improved.
  • While adjusting your antenna, it may be helpful to access the “signal strength meter” on your digital-to-analog converter box or digital television to determine whether your adjustments are improving the signals’ strength. The signal strength meter is usually accessed through the menu feature on your remote control. Refer to the owner’s manual of your device for detailed instructions on how to access its signal strength meter. Remember to do another channel scan after you have adjusted your antenna.
  • Television stations broadcasting in digital use both the VHF band (channels 2-13) and UHF band (channels 14-51). Many indoor antennas use “rabbit ears” for the VHF band and a “loop” or “bow-tie” antenna for the UHF band. Make sure you are using an antenna that covers both the VHF and UHF bands and have connected it properly.
If You are Still Having Difficulty:
  • Until June 12, 2009, some stations will be operating at reduced power levels. If you are not receiving certain digital TV stations, this does not necessarily mean there is a problem with your antenna or digital-to-analog converter box or digital television. Check with the TV station to find out whether they are planning changes that will improve reception.
  • When an analog TV signal is weak or receives interference, static, snow, and distortion will often appear on the screen. Digital broadcasting will provide a clear picture; however, if the signal falls below a certain minimum strength, the picture can disappear. This “cliff effect” means that if you watch analog TV stations that have static and distortion, you may have to adjust or upgrade your antenna system.
  • Simple indoor antennas provide minimal performance that may not be suitable for your location. If you are unable to obtain satisfactory DTV reception with your current indoor antenna, you may wish to obtain an indoor antenna that includes features for better reception of UHF signals, as well as VHF, and/or an amplifier to boost the received signal (often referred to as an active indoor antenna).
  • Generally, an outdoor antenna will get better reception than an indoor antenna. However, the performance of outdoor antennas can degrade over time due to exposure to the weather. If you are having problems, check for loose or corroded wiring, broken antenna elements and that the antenna is pointed in the right direction.
  • Try to keep the length of wire between your antenna and digital-to-analog converter box or digital television as short as possible for best reception.
  • “Splitters” that are used to connect a single antenna to multiple digital-to-analog converter boxes or digital televisions reduce the amount of signal available to each device. If you are having problems, check whether reception is improved without the splitter. In some cases an “active” splitter that includes an amplifier can solve the problem.
  • If you are near a station’s broadcast tower, reception of that station, as well as other stations, can be impeded by strong signal “overload.” Consider using an “attenuator” or removing amplifiers to improve your reception.
  • If you decide to replace or upgrade your indoor or outdoor antenna, many types are available from electronics retail stores at a variety of prices. Websites such as www.antennaweb.org provide information on the locations of broadcast towers and the types of outdoor antennas appropriate for the stations you wish to receive. If you need assistance with upgrading your antenna system, check with a local antenna retailer or antenna installer.
  • To check for the DTV signals that are available at your location, use the DTV Reception Maps available at www.fcc.gov/mb/engineering/maps.
Hope it may helps:

New dp 19648 sanyo hdtv no signal detected


You gotta have a way to get signal to the tv . If you don't want a outside antenna use rabbit ears .After you hook them up hide them behind the tv then do a channel scan. If you don't pick up all the stations set them on top and scan again or get satillite or cable hd boxes.

Need a smart antenna to go with the Digital TV converter box


First, you don't need a Smart Antenna, the manual is simply stating that your converter will use one if you have it. Any standard antenna will work, so there is no need for a coupon to pay for a new one, whether indoor or outdoor depending on your location and distance from each channel transmission tower. Since you don't give details of what antenna you are using, I will assume you have rabbit ears for each converter. Rabbit ears are notorious for poor reception and any metal or persons nearby will change the reception quality. I would recommend a roof mounted external antenna with splitters for the 3 converters if you have the option. If not, use an amplified internal antenna and mount it closest to the channel towers you will watch most and as high as possible. If you can find a smart antenna, which is an amplified indoor/outdoor antenna with a control cable for changing the direction of reception, for a decent price, you can use that but keep in mind that to use the control feature you will need one for each converter. Also, check antennaweb.org for information on digital channels in your area and their direction and distance. Antennaweb.org will also tell you if any digital channel in your area uses VHF frequencies. If they don't then a UHF only antenna will work fine.
