Do you have a multi-meter? You can test the power supply to make sure it's putting out the proper voltage, if it's junk you could get a replacement, but if the talkbroadbox is bad, then you're looking at replacement. If the power supply is good, plug it into the Broadtalk box and when it's inserted try putting a little, very little pressure on the connection at the box in a circular motion. Sometimes the poles that connect the power plug into the main bord can break, if they have, you could probably have it seviced, unless you know how to do that, but if you don.......DON'T. You don't need a fire because you wanted to save a couple of dollars. Also check the cable from the power converter to the connector, make sure it isn't cut or show any excessive wear and tear.
