The first step is to check V+ Line whether the pin connections and the antenna is connected properly or not. If the pins are dirty or not well connected, do improvements in these areas.
The second step is to check the antenna path as shown below. Check one by one if there is a spur that is broken or not, if there is a path-breaking try doing jumpers carefully and thoroughly.
Tissue repair instructions or signals on the Nokia Lumia 1320.
Check antenna paths are connected by a resistor. if the resistor is damaged then this fairly easy for us to change.
Check the path from the antenna to the IC to the PA.
Also check the path of the IC PA headed to the antenna switch. see the picture above.
If all lines in a normal state simply to replace the IC PA or antenna switch. See the picture above
Note: when we replace both component IC should be careful, if you use the heater for removal simply to reduce its volume.
