Open the phone and check for liquid damage.
Make sure the antenna connector (W100, Fig. 2.1) is not incorrectly soldered, mechanically
damaged, dirty or oxidised. Clean, re-solder or replace if needed.
Check the solder joints at N200, Z200 and Z201.
Measure the resistance over L200 and L201 (0 ohm).
Replace if incorrect.
Remove L204 and measure the resistance from pin 2 of Z200 to ground (>100 kohms).
Usually the resistance is only a few ohms when Z200 is faulty.
If the resistance is incorrect, replace Z200 and mount L204.
If the fault remains, send the unit on according to the local company directives.
