@ abdul:
Removing the TVSS can cause the RxDiv alarm since there is still a TVSS on the other transmission line. Having it in place, though wet, will not affect Rx as much as Tx due to the relative power levels between them. In place, the RSSI on that line is similar to the RSSI on the other line, hence no alarm; remove one TVSS and you can see RSSI levels increase dramatically. If you have access to a spectrum analyser, that may help you narrow things down.
Additionally, if you had water in the TVSS it is HIGHLY likely there is water in the adjacent connectors and possibly up the main feedline and down the jumper to the BTS.
