How to Troubleshoot a Sceptre TV

By Ross Glyn

Sceptre Technologies, based in the City of Industry, Calif., has been producing LCD HDTVs since the early 1980s. Their products can be found in a number of large, relatively cheap retail stores. As with many consumer electronics, glitches can occur. Whether it be an issue with picture quality, or condensation forming inside the unit, the problems are relatively simple to remedy. Before taking your TV in for service, there are a few basic troubleshooting steps you can run through on your own.

Step 1

Connect the power cord correctly and turn on the power to the TV if the unit will not power on. Test another appliance in the same socket to check that it is "hot." Inspect the household electrical panel for any blown fuses or tripped switches. Reset breakers and replace fuses with others of the exact same amperage. Replace the batteries in the remote control, if necessary. Use the "Source" button to select the correct signal input.

Step 2

Check that the video cables are connected correctly if the color quality of the picture is abnormal. Match the colors on the cables to the jack ports on the back of the TV (i.e., red-colored cable to red-colored port).

Step 3

Adjust the "Contrast," "Brightness" and "Lamp Setting" settings from the OSD (On Screen Display) menu if the picture is too dark.

Step 4

Check to see that you have connected both the audio and video cables if you have audio but no picture. The TV tuner signal must not be lower than 65 percent.

Step 5

Turn the TV off and allow it to sit for a few hours if condensation forms inside the unit and the picture becomes blurred or distorted. Moisture can sometimes form inside the TV if there is a sudden change in temperature from cold to warm. This can also happen when the TV has been sitting in the path of an air conditioner draft, and then the air conditioner is turned off.

Step 6

Check the "Auto Lock" function's settings inside the OSD menu if you are unable to receive certain channels. Someone may have previously locked up some of the channels.

Tips & Warnings

  • It takes roughly 10 to 12 seconds for the high-definition liquid crystal screen to display picture after the unit has been powered up.
  • Unplug the TV during electrical storms and when not in use for an extended period of time.
  • Keep heat sources such as radiators, heaters, amplifiers and stoves at least five feet away from the TV.
