171, 179, 180

Aim Tune In at your TV and press Power. Your TV should turn off. If it does not, repeat steps 2-5, trying each code listed in step 4 until you find the one that operates your TV.
Now Test Your TV
Why test? Many times more than one code appears to work. Testing is desirable to be sure you have the correct code for your TV or the other devices you are setting up.

Press the Power key to turn on the TV, then press mute, channel scan ("CH") and volume ("VOL") keys. Tune channels 7 and 11 by entering the number followed by the Enter key.
If your TV does not pass the test, return to Step 2 at the top of this page. Enter the next three-digit code and repeat the process.
