How to Troubleshoot a Westinghouse TV LVM-37W3


Westinghouse's 37-inch HD-ready LCD TV and monitor brings high-quality video images and sound into your home, providing sharp images for video games, DVDs, excellent sound for auxiliary audio devices and a large-format monitor for your computer. If your TV is new and you are having problems, recheck all of the connections to make sure they are tight and that the cables are connected to the correct ports. If you are still having trouble, a few troubleshooting tips will help.

  • Check to see if the power cord is connected to the AC jack on the back of the TV, that it is plugged into an electrical socket and the power outlet is working if there is no power going to the TV. The TV will normally take longer to come on when it is set to E. Saver; if it is taking too long for your comfort, change the Power menu setting to normal.

  • Open the remote control to see if the batteries are inserted properly if the remote control isn't working. Replace them if necessary. Press one button at a time.

  • Examine the video connection if there is no picture. The video cable connected to the TV should be connected to the video output port at the back of the computer. Tighten the video at the TV if it is not attached permanently. Make sure the antenna is connected properly. If you still have no picture, adjust the brightness and contrast.

  • Check the VGA cable connection if you have no picture or the message No Input Signal. If that does not work, try lowering the video resolution on the computer and unplugging and replugging the video cable.

  • Use Auto Adjust or check that the aspect ratio is set correctly if the picture is cut off or you see bars at the edges. If the aspect ratio is set to Fill (the picture fills the screen), you could see bars at the top, bottom or sides of the picture. For viewing programs with a 4:3 aspect ratio in their normal format, select Standard as the aspect ratio.

  • Check the antenna connection and reduce the number of signal splitters and the length of cables if the picture is pixelated (lots of small square blocks instead of a continuous image). Replace worn cables and connectors.

  • Connect the TV to another computer if the colors you see are wrong. Recheck the video cable connections to make sure they are secure.

  • Check the antenna connection and the TV/CATV selection if you get a snowy picture.

  • Examine the audio connection if you have no sound on the TV. If you see the word Mute on your screen, press the "Mute" button on the remote. Use the "Volume" key on the remote control to increase the volume in case it is set too low.
