Replace any damaged cables, and if the damage is on the input ports, take your device to Sharp TV’s authorized service center for repairs. If you have bought a new cable, ensure it is securely connected to your TV. If your Sharp TV has a warranty, you can replace the faulty component for free if it comes under a manufacturing defect.
Check the Input Settings on Sharp TV
Use your remote control to navigate to the input menu, and ensure the correct input source is selected for the device you’re connected to.

Sometimes, the input issue on Sharp TVs may occur because of a faulty device. To confirm this, connect a new external device to your Sharp TV using the HDMI cable. Then, change the source on your Sharp TV to the one you plugged in. If the source displays the content of the connected device, you can confirm that the issue is with your old device.
