TV won't switch inputs or sources

Symptoms

• Pressing input/source button does nothing
• Input menu opens but selecting an option doesn't switch
• TV is stuck on one input even after using physical buttons
• Input switching worked before a recent update

Likely causes

• CommonRemote or TV software glitchA temporary freeze in the TV's menu system can make the input selector unresponsive even though the rest of the TV works.
• CommonHDMI-CEC conflict with a connected deviceDevices using CEC (like a game console or soundbar) can sometimes fight for control of input switching.
• PossibleRemote itself not sending the input command properlyA worn button or low battery can cause the input command specifically to fail while others work.
• Less commonFaulty input selector circuitIn rare cases, the hardware responsible for switching inputs can fail.

What to do

1. Try switching inputs using the TV's physical buttons instead of the remote to rule out a remote issue.
2. Unplug the TV for 60 seconds to force a full restart and clear any software freeze.
3. Turn off HDMI-CEC (sometimes called Anynet+, Bravia Sync, or SimpLink) in settings, then try switching inputs again.
4. Replace the remote's batteries and test the input button specifically.
5. Disconnect all HDMI devices except one and see if switching to that single input works normally.
6. Reconnect devices one at a time to identify if a specific device is causing a CEC conflict.

When to call a pro

If input switching fails using the TV's own physical buttons after a restart, a technician can check the input selector hardware.
