Maybe a bleeder resistor between vcc and vdd is needed to make sure the voltage goes to 0V on every turn off ? Try 2k7 for 3V. This may or may not upset the power budget. You could hot-connect the resistor to the returned unit. Just use a soldering iron with the cord unplugged. Peter -- http://www.piclist.com#nomail Going offline?
