How To Troubleshoot A 40 Inch Samsung LCD TV

Educate yourself on how to troubleshoot a 40-inch Samsung LCD TV so you won’t need to contact a service technician. These massive screens can present equally intimidating issues, but you’ll be able to handle them with the troubleshooting tactics in the list below. Take a thorough read through the manual before attempting any repairs. 

To troubleshoot a 40-inch Samsung LCD TV, you will need:

• Remote control
• TV cables 

1. Get out of “Shop Mode.” Many Samsung customers have been frustrated when they spend time setting all of their favorite television preferences, only to find them reverted back to their default settings. Your Samsung LCD TV is acting this way because it’s in “Shop Mode.” This is the mode retailers use when they sell the product to customers, demonstrating all of the LCD TV’s features. Get yourself into one of the normal modes for home use by holding down the “Menu” button on the television. The screen will switch to one of the different modes. You can choose which one you prefer.
2. Secure the wires. Countless video- and audio-related issues, such as superfluous background noise or popping sounds in the speakers, are due to loose or weak connections, especially if external speakers are connected to your LCD TV. Turn the TV off and unplug it from the wall. Now, check all of the connections coming in and out of the television unit. Make sure they’re firmly in place. An older cable might need a harder push to secure it in its socket. Now, plug the TV back into the outlet and turn it back on.
3. Check the power cord. If you’re stuck with a TV that seems to have no power, check that the cord is fully plugged into both ends—the television unit and your wall outlet. It’s best if your Samsung LCD TV is plugged directly into the wall so do away with any types of extension cords or power bars. There should be a standby light at the front of the TV. If the light is on but the TV still doesn’t show anything on the screen, it may be an issue with the video and not the power.
4. Turn off TruSurround XT. This special feature of Samsung LCD TVs provides the user with real surround sound even without various speakers installed around your room. Unfortunately, the sound display might actually seem warped when you use TruSurround XT with certain channels. Access this feature to turn it off using your remote control. Just press the button entitled “SRS.”
