Question about Samsung LE40R74BDX 40 in. LCD Television

1 Answer

No signal or intermitant signal

Have a large winegard antenna 32 feet high, new rotor, new pre-amp, new coaxial cable, new connections, still 1 station at best. I've tried
Magnavox. Zenith, DTV Pal & RCA Boxes. RCA is the only one I can
get 1 station on. Any words of wisdom? I'm 32 miles from the closest
TV tower. Weather seems to effect the digital signal greatly.

Sounds like cable or satellite are your only options unless after the switch they bump up the power.

Televison station won't scan


If you are receiving a "No Signal" error message, verify that:
  1. All of the cables physically connected to the TV and the input device are secure.
  2. The input device is turned on.
Your TV needs to scan for channels before it can show programming from an antenna, from cable TV when the cable comes directly from the wall (no cable box), or from a cable or satellite box connected to the TV with a coaxial (RF) cable. Do not scan for channels if you have a cable or satellite box connected using AV (Composite), Component, or HDMI cables. The box selects the channel, not the tuner inside your television. If you are not using the "TV" input, press the INPUT button on your remote until the correct input mode is selected.
To perform a channel scan using the coaxial input:
  1. Press the INPUT button on your remote to view your current input source. The TV (coaxial cable) input must be selected. This may appear as "TV," "ANT," or the channel and call letters of a station.
  2. If the TV input is not selected, press INPUT until the TV input mode is selected.
  3. Open the on-screen menu and select TV or Tuner option. (This varies by model.)
  4. Highlight Tuner Mode and select the correct option:
    • Antenna-over-the air signals from an antenna
    • Cable-direct from the wall cable TV, or a cable or satellite box connected to the TV with coaxial cable
  5. Select Auto Search or Auto Channel Scan. (This varies by model.)
  6. When the search reaches 100% complete, exit to the menu.
  7. Check the available channels:
    • Antenna or direct-from-wall cable-Press the Channel Up and Channel Down buttons on your VIZIO TV remote to view the available channels.
    • Cable or satellite box- Will return only one channel. Use the cable or satellite remote's Channel Up and Channel Down buttons.
If this does not resolve the issue, power cycle the TV and then re-run the channel scan:
  1. Turn off the TV.
  2. Unplug the TV from the electrical outlet.
  3. While the TV is unplugged from the wall, press and hold the Power button on the TV for 30 seconds.
  4. Release the power button.
  5. Plug the TV back into the electrical outlet.
  6. Turn on the TV.
Note: There is also an option to reset the TV to the factory default settings. This option is in either the SETUP or SYSTEM section of the on-screen menu. The option may be "Reset all settings", "System Reset," or "Reset & Admin." Consult your TV's user manual for the location and steps for resetting your model.
  1. Remove the coaxial cable from the DTV/TV connector on the back of your television and perform a channel scan to clear the existing channels. See the procedure above. This should not find any channels.
  2. Re-attach the coaxial cable to the DTV/TV connector and perform a new channel scan.

My panasonic viera has just stopped working. I can play a dvd but not watch tv, It says no signal. I have checked all leads and none are loose. It worked yesterday!! What is wrong with it? Please help


What is your TV source? Is it OTA, cable or satellite? Do you use a set top box or a direct coax cable connection? If you have OTA, what antenna do you use?

Try the following depending on your setup:

For all, check if a lightning/surge protector has taken a surge and needs to be replaced. These are placed in the coaxial line to divert a surge that could destroy your electronics. Also try replacing the cables. Check exposed cable for damage.

For OTA, first check that your antenna is oriented to point to the transmitters in your area. (Outside antennas will sometimes turn in the wind; indoor ones can be bumped.) Try a new coaxial cable. If the antenna has an amplifier (or you use a splitter with or without an amplifier), try connecting the cable directly without the device. I've had several amplifiers fail and turn into signal filters (blocking all of the signal).

For any system with a set top box, make sure that the box is on. For satellite, make sure that your dish hasn't moved out of alignment.

To check if it is the Viera TV tuner or the incoming signal, try another TV at the same connection. If you have cable and another TV gets no signal directly connected to your incoming connection, you may need the company to fix the incoming cable. (Underground cables can be damaged by rodents or neighbors who dig without checking for utilities.)

I hope this helps.

I just acquired a Toshiba 32HL95 TV and cannot get any hd channels although I have a digital cable box. I have tried using the coaxial, hdmi and video connections to no avail.


Try configuring your antenna input. Menu, Installation, Terrestrial, Input Config select your antenna 1 or 2 and > arrow over to select cable. Next auto program: under Terrestrial, Channel Program...this take some time.

I NEED SONY BRAVIA T32 FULL MANUAL...how to conect to computer and camera


Hello there,

Here is the link to the full manual:
http://support.sony-asia.com.edgesuite.net/consumer/IM/4110401121.pdf

Before connecting your devices...
The signals that enter the TV and connected devices will need to be output in the correct format using the suitable connections. Below are the different types of video connectors. When connecting the TV, use the inputs that are available on your devices that provide the best video performance.
Video performance level Name Aspect Signal transmitted Separate audio connection required arrw.jpg HDMI cnn_hdmi.jpg Picture + Sound No DVI*1 cnn_dvi.jpg Picture Yes
l.jpg r.jpg
L-AUDIO-R Component video cnn_component.jpg Picture S-Video cnn_s_video.jpg Picture Composite video cnn_composite.jpg Picture RF/Coaxial cnn_coaxial.jpg Picture + Sound No
*1 If the equipment has a DVI jack and not an HDMI jack, connect the DVI jack to the HDMI IN (with HDMI-to-DVI cable and/or adapter jack), and connect the audio jack to the AUDIO IN (L/R) jacks of HDMI IN. (The DVI connector is for video signals only) To enjoy the best visual experience with your system, it is preferable to connect your best devices with the highest quality connections available. For example: your Blu-Ray Disc player or HD Set Top Box with HDMI, followed by your DVD player with Component, then your Video Cassette Recorder with S-video etc.Note: The quality of the picture also strongly depends on the quality of the cable used.
HDMI The High-Definition Multimedia Interface (HDMI) is an all-digital audio/video interface capable of transmitting high definition video and audio signals. HDMI provides an interface between any compatible digital audio/video source, such as a set-top box, a DVD player, a PC, a video game system, or an AV receiver and a compatible digital audio and/or video monitor, such as a digital television (DTV). DVI The Digital Visual Interface is capable of transmitting high definition video, but does not transmit sound. You will need to use the audio connectors of your device (usually Optical/Coaxial digital, or RCA). It is possible to connect an HDMI device to a DVI device using a HDMI to DVI adapter. Component video Component video is an analogue connection. It is capable of transmitting high definition signals. Component does not transmit sound. You will need to use the audio connectors of your device (usually Optical/Coaxial digital, or RCA) S-Video Separate video, abbreviated S-Video and also known as Y/C is an analogue video signal that carries the video data as two separate signals (brightness and colour), unlike composite video which carries the entire set of signals in one signal line. S-Video, as most commonly implemented, carries standard definition video. It does not carry audio on the same cable. Composite video Composite video is an analogue video (no sound) format. This is the connector you should use if you do not have any other connector available, in terms of quality. RF/Coaxial RF Coaxial Cable connection is used for transferring television signals (audio and video) originating from an antenna or cable box to a Television.

Goodluck

I have a Sanyo DP32648 that keeps losing only one channel in the program. When the TV is turned off, that channel disappears from the program. I have to manually reboot the entire list. How can I solve...


It sounds like there is some electrical noise interference that would not be "fixable". If though, we reconfigure the way that they are connected together, we may be able to avoid the noise.

Instead of allowing the antenna signal to "pass through" the 625 we will skip it.

After following the directions, switching between satellite and antenna will be done by selecting on the SANYO "Input 1" for satellite, and selecting "Ant" for antenna. K?

Try this:

From the 625 Tuner 1- using RCA cables (a.k.a. composite cables, or red, white, yellow cable), connect to "Input 1" on the Sanyo TV. To see composite cables go to http://www.wowvision.tv/settingsandconnections.htm

Next, remove the coaxial cable between the Sat box and TV. (Sanyo "Ant. In" port and 625 "Out to TV" port) Set that cable aside.

Now, remove the incoming antenna cable from the 625 "Ant. In" port, and connect it to the Sanyo's "Antenna In" port.

Finally, scan for channels and check for the presence of CBS.

Once verified, test the TV by turning off and on.

Turn on the satellite receiver and switch Sanyo to "Input 1" to verify sat picture.

I believe this solution will satisfy your needs. Please let me know if it doesn't work, and I will need to talk to you about signal strengths, again.

God bless,

Sony kdl46w5150 with external antenna dropping signal on some channels


1. Check for any loose connections starting at your TV. (Coaxial cables unscrew themselves with vibration...) Check all outdoor connections for corrosion and cut off and replace any cable ends that show corrosion.

2. Check your alignment - (positioning or pointing)
http://www.wowvision.tv/OTAalignment.htm

3. Replace the balun a.k.a. 75 ohm matching transformer.

If these don't work, a larger antenna is needed...

with one exception:

That exception is if your signal is too high. If this is the case, change alignment to reduce signal a little.

Sharp digital tv cannot receive digital signal


This television would benefit from an hdtv indoor outdoor amplified antenna not obstructed by trees, aluminum, bricks, and etc. Make sure the signal type is air and not cable and complete a channel scan during primetime tv hours after connecting to this antenna. Buy a large one that you can mount to the wall usually in a large flat box on the shelf in the store. Philips has one sold at Walmart.

Hi and welcome to FixYa,

To get a good signal on all TV units, the source must be good and strong. The source could be an aerial antenna or connection to your local cable provider. The message "No Signal" indicates that the TV cold not receive a decent TV signal. With this in mind, possible solution wouold then be to increase/improve the incoming TV signal:
  • if you are using an aerial, 'height is might' to overcome any line-of-sight obstruction. Additionally, there are antennas with higher gain, meaning they could receive better than other antennas. Another option is installing a pre-amp or commonly called booster;
  • if you are hooked to a cable provider then it may be to your advantage to bring this concern to their attention. They could try transferring you tap off point to a better distribution box, replace your coaxial cable with low loss or even in some cases, install an inline booster;
  • possible RFI (radio frequency interference) which could come from wireless phones, garage door openers, WiFi, electronic dimmers, electronic ballasts of high density lamps and others. If any are present or within the immediate vicinity, pls try to relocate or reposition.
Just a start, do postback how things turned up or should you need additional information. Good luck and Thank you for using FixYa.
