I believe I can help, I have the same one. First push the device button you want to program, for example we will program your t.v. First push the t.v. button on the remote, then push and hold the t.v. button down and the on/off button and hold them down at the same time until the on/off button light comes back on and stays on, then alternately push the on/off button then the CH+ or channel up button, on your remote while pointing it at the t.v.  until it comes on or goes off, each time you hit the CH+ button you advance to the next code until you go thru all the codes programmed in the remote. After the t.v. goes off or on you have found the code for your t.v., then just hit the stop button on the bottom and the on/off button light goes out and the code is stored, hope this helps.
