TX phase faulty
Check TX spectrum with analyzer – refer to page# 46
If the following spectrum appears – check components in TX I/Q lines for shorts:
In some cases (especially after rework in COBBA area) R708, R710, C708, C709 (near COBBA N200) could be misplaced.
If the components are ok – change COBBA N200 if not underfilled.
NOTE:
If COBBA was changed - SIMlock and IMEI entries must be rewritten with NOKIA Security Password, if this procedure is
permitted to you!
TX phase faulty in high channel range in GSM1800
Check TX spectrum with analyzer – refer to page# 46
Check mechanical appearance of Z504
If measurements are ok – change Z504 – in some cases the bottom side of this component could be teared off because of
mechanical stress, which only could be seen if the component is removed.
