Samsung is currently the world's leading consumer electronics company. Consumers know Samsung's plasma TVs for their vibrant colours, picture quality and contrasts. You may still run into problems with your Samsung plasma TV that you don't know how to solve. Try troubleshooting them on your own before you contact customer service.
Perform the picture test if your Samsung TV is providing a poor picture. This will confirm that your TV is correctly displaying the image. Go to "Menu," then "Support." Select "Self Diagnosis" and then choose "Picture Test." Check the source or signal for the problem if the test image is properly displayed. Inspect all of the cable connections to make sure they are secure. Unscrew the cable connector from the wall outlet and make sure the pin is straight, not bent, and not corroded. If your problem persists, contact the cable company.
Make sure the sleep timer is programmed to "Off" in the Setup menu if your TV turns off automatically. If your PC is connected to your TV, check the settings of the computer to see if it is turning off the TV. Verify that the AC power cord is plugged in tightly to the electrical socket and to the television. If you are watching the TV from an antenna or cable connection and there is no signal, the television will turn off automatically after 10 or 15 minutes.
Set the brightness on the TV to a lower setting if a loud humming noise is coming from your set. Remember that plasma TVs always make a low humming noise. The noise is caused by the electrical charges used to create the images on the screen. If the back of your TV is too close to a wall or another hard surface, it may also make a loud humming sound. Make sure that if your TV is wall-mounted, it is properly attached to the wall. Unbalanced or unsecured mounting can also cause noise.
Program the "Speaker Select" option to "TV speaker" in the Sound menu if the TV picture is good but there is no sound. If you are using an external device, such as a cable box, make sure the audio cables are connected to the proper audio input jacks on the TV. You need a separate cable if you are using a DVI or HDMI cable. Make sure nothing is plugged into the TV's headphone jack.
Upgrade to an HD digital set-top box, as opposed to an analogue cable/satellite box, if the TV image does not look as good as it did in the store before you bought it. HDMI or component cables need to be used to deliver HD (high-definition) picture quality. If you are a cable or satellite subscriber, try selecting HD stations from the channel line-up. If this does not work, adjust the Cable/Satellite box resolution to 1080i or 720p.
