Have you tried the searching for your code option on the 15-2147?
for example, turn on your Emerson LC200EM8( press the appropriate key on your remote, if this is a TV.#1.press the tv key on your remote)..#2.Press and hold the little 'p' key till the LED lite,on the remote, blinks twice..#3..then enter 9 9 1.(the led should blink twice).#4.Aim and..Press the Power off on the remote....(the remote will start sending IR codes from its library to the selected device, starting with the most popular.)#5..If the TV responds go to step 6..if not, press the CH+ button, until it does...step #6 when device responds, to lock in the code, press 'p' once, the LED blinks twice.
Once you have your number locked in,,,you can get the remote to tell you what sequence the code is in by #1Press the appropriate key on the remote.(i.e, TV press the TV key ....Dvd player or VCR, then press that key). (Note: make sure you are aiming the remote at the device so the IR(infrared) enters the device.) Step #2 Press and hold the 'p' key(upper right corner of controller) until LED blinks twice, then release....Step #3 enter the code 9 9 0 ..the LED lite blinks twice. ..Step#4 to get the first number of the code press th e number 1 on the controller...the LED will blink the once for 1 //twice for 2...three times for3...etc...write down how many times the LED blinks(if it doesnt blink the first number of the code is 0) Repeat step #4 to get the remaining numbers, i.e. for the second mumber of the code enter 2...third number enter 3...till you have all four numbers.( when done you can press a different device key to get you off... then press the right device key for your device to operate it remotely. Hope this helps
