How to Troubleshoot Samsung Televisions
The old days of hitting the top of the television with the palm of your hand to get the picture to stop rolling are long gone. Even snowy images aren't around anymore because of digital broadcasts. Televisions now use tube-less liquid crystal (LCD) and plasma displays with solid state circuitry. However these new technologies can bring trouble---just a different set of problems.
Check all the cabling connections for tightness in the picture is flakey. Some cables can become easily disengaged, especially S-Video cables.
Check the power is connected and the television is turned on if there's no sound or picture. Make sure the source is also connected to the power.
Check that the input button on the remote is selecting the right source. If you have a DVD and a cable box for example, make sure that there's a DVD playing if the source is DVD. Make sure the cable box is on if the source selected is cable.
Check the brightness and contrast settings if the image is too light or too dark. There's usually a default setting in the menu. Try that.
Press the zoom and display buttons on the remote control if the picture doesn't fill the screen as it should. New TVs can display in many different sizes. A DVD's input may require a different screen setting to a cable channel for example.
Tips & Warnings
- The odd black or red spot on the screen is normal and is part of the manufacturing process.
- Clicking noises are normal too. They are created as the television heats up and cools down. Plasma televisions can get pretty hot due to the gasses heating. For this reason, keep children from touching the upper part of the screen when it's on.
