How do you change the input on a TV without the remote or buttons?

Changing the input on a TV without using the remote control or physical buttons can be a bit challenging, but it's possible in some cases. Here are a few methods to try:

1. Universal Remote App:
If you have a smartphone or tablet with an infrared (IR) blaster or an app that simulates one, you can use it as a virtual remote control. Download a universal remote control app like "AnyMote," "SURE Universal Remote," or "Peel Smart Remote" and set it up to control your TV.
Launch the app, select your TV brand and model, and look for an option to change the input source. This will vary depending on the app, so follow the on-screen instructions.
2. CEC (Consumer Electronics Control):
If your TV and connected devices support HDMI-CEC (Consumer Electronics Control), you can try using it to change inputs. CEC allows HDMI-connected devices to control each other.
Ensure that your TV and the device you want to switch to are both connected via HDMI and support CEC.
Use the remote control of the CEC-enabled device to power it on, and the TV should automatically switch to the corresponding input.
3. Smart Assistant Voice Control:
If your TV is a smart TV and you have a compatible smart assistant like Amazon Alexa or Google Assistant, you may be able to change inputs using voice commands.
Make sure your TV and smart assistant are set up and connected to the same Wi-Fi network.
Use voice commands like "Alexa, change TV input to HDMI 2" or "Hey Google, switch to HDMI 3 on the TV."
4. HDMI-CEC Adapters:
If your TV and devices do not support HDMI-CEC, you can explore HDMI-CEC adapters that can be added to your setup. These adapters can provide CEC functionality to devices that lack it.
Connect the HDMI-CEC adapter to your TV and the device you want to control. Follow the adapter's instructions to set it up, and then you may be able to switch inputs using the device's remote control.
5. Use a Physical Remote:
If you have a universal remote or a remote control from another device that uses the same infrared (IR) frequency as your TV, you may be able to use it as a makeshift remote.
Point the remote at the TV, press the power button, and check if the TV turns on. If it does, you can navigate through the on-screen menu using the remote's arrow keys and select the input/source option.
6. Contact Customer Support:
If none of the above methods work, consider reaching out to the TV manufacturer's customer support. They may be able to provide guidance or suggest alternative solutions based on your TV's model and features.
7. Purchase a Replacement Remote:
If all else fails, you can purchase a replacement remote control for your TV. Look for an original remote or a universal remote compatible with your TV model. This is often the most reliable and convenient solution.

Keep in mind that the effectiveness of these methods depends on the specific make and model of your TV and connected devices. While some newer smart TVs offer advanced control options, older or more basic models may have limited alternatives for changing inputs without a remote or physical buttons. Experiment with the available options, and if necessary, consider investing in a replacement remote control to simplify the process of changing inputs on your TV.
