SOURCE: Green box keeps popping up in upper right corner

You should be watching your dvd's on an input and not on tv analog 3. Every time the tv "senses" a signal change in the audio that screen will pop up. Connect the DVD player to the tv by using either the red, white and yellow (composite) connections or using the green, blue, red, white and red (component). Once you are on an actual input that box will stop popping up.

SOURCE: Aspect ratio problems on Samsung LN-S2651D Flat Panel TV

The aspect ratio (zoom) button on the cable remote had been changed. On Brighthouse the # button toggles through the zoom settings. It's not a tv issue, it's a cable fix.

SOURCE: digital converter box setup

Hi Kilroy75,

It sounds like you probably set this up properly. The converter box is powered on, indicated by the blue light (it is illuminated red if powered off). I would recommend that you check to see if your TV has to be on a specific channel to receive external input.

To double check the connection, you should be able to follow the antenna into the converter box, then the converter box into the TV. Check to make sure you have input/output correct, and that video matches video, audio matches audio, etc.

Also, some antennas require power. If this is the case, make sure the antenna is plugged in and powered on.

If none of these suggestions help, I would try a little troubleshooting to determine which piece of equipment is giving the problem. Try connecting another device into the same input to see if your TV receives signal through input 1. You may also try a different set of A/V cables or a different input on the TV.

If you still are unable to get your setup working, I recommend you bring the converter box into your local Geek Squad® precinct for further troubleshooting and advice.

Thank you,
Jason,
Go Ahead. Use Us.

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.
This video shows troubleshooting steps to use when a "No signal" message appears.

NO PICTURE


Refer to the manual (free download here). Generally, a blue screen indicates a very low or non-existent signal. This can happen when the antenna is unable to gather enough of a signal from a particular broadcaster, or if an A/V input is selected, but the A/V device is not on or providing a signal. Since you are not seeing channel information when tuning, I suspect that the television is set to display an A/V input instead of the internal tuner.

With a working remote, locate the TV/AV button on the lower left (manual page 3 - item 8). When this button is pressed, you can choose to display signals on the ANT, VIDEO1, VIDEO2 or COMPONENT jacks. The ANT selection chooses the input on the RF jack such as an antenna or cable TV (with or without converter box). If using a cable box, the TV tuner should be set to Ch3 or Ch4 as determined by your cable box. Otherwise, select the VIDEO1, VIDEO2 or COMPONENT input that has the source signals you wish to watch from a cable box, DVD player, etc. that is connected to the rear input jacks. Page 7 of the manual details the connection and remote operation.

I hope this helps!

I own an Insignia flat screen tv, NS-LCD27, & I was given the Insignia converter box, NS-DXA1; how do I program tv remote for the box? Thanks, frances b.


The digital to analog converters did not exist when the TV was built and the remote programmed. Thus you will have more luck programming the converter box's remote to control the TV. (At least with my converter box, the included remote could only turn on and off the TV. It would only change channels on the converter.)

Most universal remotes only have codes for devices released 6 months or more before the TV was programmed. So a new universal remote will probably control both the TV and the converter box. (Program the converter box using a code for LG or Zenith set top boxes if Insignia isn't listed. LG makes Insignia video products for Best Buy.) The remotes that are programmable by a USB connection to a computer are the fastest to set up.

A replacement remote for your TV is available here: http://www.mcmelectronics.com/partfinder.aspx?brand=&mdl=NS-LCD27&mode=part . An exact replacement remote for the converter box can be purchased at: http://www.remotes.com/remotes/servlet/rs?a=gmi&uuid=13055197980390&smodel=NSDXA1&brand_pn=INSIGNIA_NSDXA1 . The manual for the converter box (as a PDF) is here: http://cbsdallas.files.wordpress.com/2011/01/insignia-ns-dxa1-manual.pdf .

I hope this helps.

Turn on goes blue then turns off


The most common reason for a TV to display a blue screen with no picture is because the source device has not been set to the proper mode.

If you are using a cable or satellite set-top box, ensure that it is turned on and set to an active station. If the set-top box is connected to the television using a coaxial cable, then the television should be set to Channel 3 or 4 to receive the signal.

If you have are using a VCR that is turned on, but not playing a tape and not tuned to a receivable channel, then a blue screen will be displayed on the TV. To resolve this, turn off the VCR or tune it to a receivable channel. If a cable or satellite set-top box is connected to the VCR using a coaxial cable, then the VCR should normally be set to Channel 3 or 4 to receive the signal.

If the blue screen is not because of a connected VCR or set-top box, the TV may require service.
