can someone tell me where is the test point for xperia tx found

You must find it by yourself. Disassembly your phone, disconnect battery, connect each golden point one by one to gnd (metal shield, sim card reader etc.) and attach usb cable. If you will see new device in device manager - that's it. Make a good picture of it, mark testpoint and attach it here
