Universal remotes only work when the correct code is entered into it. Some codes for the same make will work other models, but things are either missing or function differently. You need to find the correct code and try the functions using it. If everything is OK then it should be fine, if not try another code.

However the best remote for the job is the original that came with the equipment. Unless you have paid out a lot of money for a universal remote, you might never get the same responses as an original remote.
