1. Using Programming Codes

Find the TV code for your TV in the list from the Platinum Remote Control User's Guide (See References). For example, if you have a Kenwood TV, the three possible codes to try are 506, 573 and 712.

Press the "TV" button on the remote. Hold down the button until the "Sat," "VCR" and "Aux" buttons light up. Release the "TV" button and it will be flashing.

Enter the first code using the keypad. If you want the remote to control all functions on the TV, enter the code and press the # key. The "TV" button will flash three times.

Press the power button to turn off the TV and turn it back on again. If the code was correct, the TV will turn off and on. If the TV doesn't power down or back on, follow Step 6.

Try the next code from the list. Follow Steps 2 through 4 using each code until one turns off the TV.
2. Programming Without Codes

Press the "TV" button on the remote. Hold down the button until the "Sat," "VCR" and "Aux" buttons light up. Release the "TV" button and it will be flashing.

Press and release the "Power" button on the remote.

Press the arrow up key and stop. If the TV doesn't turn off, press the arrow up key again. Continue pressing the arrow up key until the TV turns off. Do not go fast when moving through the codes or you could miss the correct code. Press the arrow key and wait at least 20 seconds to see if the code works before pressing the arrow key again.

Press the # key on the remote when the TV turns off to lock in the code.

You were attempting to perform a power scan initially. The second procedure is manually attempting to address the remote to your TV. I will give you the procedures again so you can try one more time. Emerson TV is one brand we have a low percentage of success getting our remotes to work. If it still doesn't work, we could try replacing the remote.

To program your remote by entering a code from a manufacturer's list, follow these steps:

1. Turn on your TV.
2. Press and hold the CODE SEARCH button for at least 3 seconds until the red LED lights up and stays lit.
3. Press the TV button on the remote so that the LED blinks once and then remains solid red.
4. Enter the first set of 3-digit codes from the list. The LED will blink once every keypress. After the 3rd digit, the red LED will turn off indicating that the code was recognized for the device. If the code was not compatible, the LED will flash several times and you need to return to step 2 to try that code again or to try the next code in the list.
   
5. After the LED has turned off, aim the remote at the TV and press ON/OFF. If the device turns off, you have used the correct code and the remote was successfully programed. If the device does not power off, return to step 2 and try again with the next code in the list.

To have the remote try each TV code it knows one at a time, follow these steps:

1. Turn on your TV.
2. Press and hold the CODE SEARCH button for at least 3 seconds until the red LED lights up and stays lit.
3. Press the TV button on the remote so that the LED blinks once and then remains solid red.
4. Press the ON/OFF button slowly and repeatedly until the TV turns off. The LED will blink once each time you press the ON/OFF button.
