First, check that the power cord is securely connected to both the TV and the wall outlet. Ensure the outlet is working by testing it with another device. If the problem persists, try a power reset by unplugging the TV for a few minutes and then plugging it back in.
To perform a factory reset, press the 'Home' button on your remote. Navigate to 'Settings' > 'Setup' > 'Reset' > 'Factory Settings'. Confirm the reset when prompted. Note that this will erase all custom settings.

You can connect external speakers using the audio output ports on the back of the TV. Use an appropriate audio cable to connect to a sound system or external speakers. Ensure the TV audio settings are adjusted to output sound through external speakers.
Check if the TV is muted or if the volume is set to zero. Ensure that external devices are correctly connected and that cables are not damaged. Also, verify that the audio output settings are set correctly in the TV menu.
