Maxcom MX-21E small plastic shelled radio. LED bargraph.

This radio turns on and lights up, it also has the usual FM hash sound so it looks like it may be working but alas there is NO TX
and NO RX. It may be down to a TX/RX switching transistor but I am not really familiar with this board so any help would be
gratefully received. :D
