I have a Mitsubishi Projection TV and I am trying to program its remote to be able to control my Scientific Atlanta Cable Box (EXPLORER 3250). The remote codes provided by Mitsubishi are 111,112,or 113.

None of these work.

I had originally programmed this remote to control my older Scientific Atlanta Explorer 2000 and it worked perfectly.

The cable company gave me the newer cable box today and I am out of luck so far - in getting the Mitsubishi remote to work.

Anyone have a suggestion? Or other codes I could try?
Cox Cable has no answers for me.

Thanks!
