Good evening, This morning before going on a day long trip my wife plugged in the AC adapter for the receiver and check to see it was working and the lights were on, definitely the red and blue, so as we were going out the door I went to unplug the adapter which was quite hot to the touch. In the car the receiver showed no lights at all and I figured that the AC adapter was fried. I plugged the cable into the receiver and then used the lighter adapter on which the light came on, but nothing on the receiver. Ideas please! I will inquire locally about a replacement battery, but the unit is just over 3 months old and it hasn't been over charged by leaving it plugged in for days.
