Programming a universal remote to work with your Toshiba LED TV requires the correct remote codes. These codes vary depending on the universal remote brand and model. Refer to your universal remote's instruction manual or the manufacturer's website for a list of compatible codes. Typically, you'll need to enter a three- or four-digit code to establish communication between the remote and the TV. If one code doesn't work, try others from the list until you find the one that controls your Toshiba LED TV's functions.
