Get your SDTV television working again.
Troubleshooting a standard-definition TV can involve many things. For example, televisions have a variety of connections, from how the cable comes into your home to the wires that actually enter your television. Then there's the television itself; it has a variety of circuits and wires within it that can also screw up. That's all before you look into the variety of settings. The good news: it's not nearly as complicated as it looks or sounds.
Instructions
1. Unplug your television from the power outlet, and keep it unplugged for two minutes. Plug it back in and power the set back up. This "hard reset" solves a lot of problems with many electronics.
2. Check your television's settings to make sure you are receiving a signal from your cable box, DVD player or other components. If you are using RCA audio/video inputs, flip through the various video modes. If you are using a coaxial connection (one wire with a screw end), make sure your television is tuned to Channel 3.
3. Check the wiring entering your television. Unplug the wires coming into the back of it, and plug them back in. Repeat this with the outputs from your device. Replace the wire, if necessary, making sure the connections are exactly the same. Ensure all wires are tight.
4. Check the signal from the cable box or satellite if your problem is with watching cable television. Make sure all the wires are completely tight. Test the device with another television to confirm it's working, if possible.
5. Check to ensure your television's volume isn't muted or all the way down if you're having problems with just your television's audio. Ultimately, if everything is set properly and you have sound but no video, it is likely that your television's picture tube is blown and you will need to replace the TV.
