It depends on the make and model of the TV. Some universal remotes are designed to work specifically with a certain brand or type of TV, while others are designed to be more universally compatible. It's always best to check with the manufacturer or retailer before purchasing a universal remote to see if it will be compatible with your specific TV.

It depends. The most common type of universal remote is the infrared (IR) remote. So if your TV has an IR receiver, then the answer is yes, the universal remote will work on your TV. However, there are other types of universal remotes that use radio frequency (RF) or Bluetooth signals to control devices. If your TV doesn't have an IR receiver, then it probably won't work with a standard IR universal remote. But it might work with a RF or Bluetooth universal remote if those types of remotes are compatible with your TV.
