Try this, just be patient as it might take a couple of minutes to program.
Here you go. This will work with most all universal remote controls. If you don't have the code do the following:
Automatic Programming
With automatic programming, the remote control tests all the codes available on the Code List and assigns the correct code for the selected device. Although this method can be more time-consuming, it eliminates the need to look up codes and enter them manually.

1. Turn off the device with which you want to use the remote control.

2. Press and hold the corresponding button on the remote control
(TV, VCR, SAT, DVD, CAB or AUD) until POWER INDICATOR illuminates. It should take a couple of seconds for the light to remain solid. The remote control is in programming mode.

3. Press and release power button. The POWER INDICATOR flashes once and stays on indicating the unit is in Power Scan mode.

4. Press CHANNEL up or CHANNEL down repeatedly until the device turns on.

5. When the device turns on, press OK to store the code.

Note:
• To exit without storing the code, press BACK.
• T he unit will search for the next code or the previous code if you press
CHANNEL up or CHANNEL down after the device turns on. (go slow you need to press OK when the TV turns on) if you mess up turn TV off and start over.
6. Press any other button. If the device responds, the remote control has been programmed. If the device does not respond, repeat steps 2-5.
