Toshiba TV owners who've lost their remote, this replacement is exactly what you need! Model CT-RC1US-19 works with various Toshiba TVs including 55LF711U20, 43LF621U19, 32LF221U19, 55LF621U19, 50LF711U20, 50LF621U19, 43LF421U19, and 43LF711U20. Important note - this is an infrared remote only, so it doesn't have voice control capabilities. If your TV screen shows 'Searching for your remote' or is stuck in pairing mode, this remote won't work until you complete that setup with a voice remote first. Once your TV is past the initial setup, this replacement works perfectly for all basic functions. It runs on 2 AAA batteries (not included) and comes ready to use right out of the package. The button layout matches the original, so there's no learning curve. Much more affordable than buying from Toshiba directly, and the quality is solid. If you're tired of getting up to change channels or adjust volume, this simple replacement remote brings back the convenience you're missing. Just make sure your TV is out of that initial setup mode before ordering!
