Guided by a Utube video I managed to get the Tablet apart, at a cost of broken finger nails, revealing the Innards..
The USB connector is on the lower edge. To remove the connector, first, using a sharp scalpel cut the 5 pins sticking out the back of the connector. If you do not, you run the risk of lifting the tracks in further activities, The four lugs can then be desoldered and the connector removed. It is then a simple task to solder the new connector in place using a fine tipped soldering iron and thin solder.
The Tablet can then be tested for correct operation before re attaching the cover. Mine charged fine and still produced video. Task completed
