DFPlayer Red LED

Hi, I am trying to use a DFplayer module with an Arduino UNO.

I wired it up following the sample tutorial and used the sample code from here: ... KU:DFR0299

I had a previous DFPlayer that seems to work ok, but two of the ones I just ordered both give me a red led when it tries to run and no audio is played.

Any ideas?
