I put in new rechargable batteries. The base unit was initially red, and after a while went to flashing red. Now, the headset won't turn on.

Hi I’m trying to connect my hdr 175 headphone to a new tv and the tv does not seem to be recognizing it. Is there anything I need to do other than plug in the optical cable?

Reading from the manual, it seems that I have a charging fault. Does that mean that my base unit is dead, and must be replaced?
