Help HTC Sensation XE - Bluetooth not working

[Mad Professor]

Good day all.

I have just brought a 2nd hand HTC Sensation XE mobile phone.
Everything is working except the Bluetooth.

Within the phones settings I can turn the Bluetooth on or off, but I am unable to see any nearby Bluetooth devices, nor can other phones see this one.

I have done a full factory wipe/reset, but I still can not get the Bluetooth working.

From reading the forums I am lead to understand that the Bluetooth & WiFi share the same antenna.

Below are some of the software details I have been able to find out this phone.

Android version: 4.0.3
HTC Sense version: 3.6
Software number: 3.33.401.153
Kernel version: 3.0.16-g31a4fc7
Baseband version: 11.76A.3504.00U_11.24A.3504.31_M
Build number: 3.33.401.153 CL391535
