Water damaged Nokia E61 - few problems remain... - GSM-Forum

I got a water damaged Nokia E61 that I have been trying to repair. When I got the phone, it would switch on, but had lots of problems charging, and would not register on a mobile network. I took it apart and cleaned the circuit board with alcohol. After the cleaning, the phone registered on the mobile network without any problems, and I have not seen a charging problem either. I even managed to successfully upgrade the firmware to the latest version.

However, there are still two problems remaining.

1) The battery seems to drain overnight if I switch off the phone (haven't tested it with the phone on yet). I re-cleaned the battery contacts and connector, but it did not help. I measure ~110 ohms between the + and - terminals on the battery with the battery out. The battery does not discharge out of the phone.

2) I have been unable to use the WLAN functionality. Bluetooth works fine, and I believe BT and WLAN uses the same antenna assembly.

Any suggestions on what I can try for either of these problems? All the circuits are encased in soldered RF shields, so I can't get to it - I just soaked it with alcohol.

As it looks like no one has any suggestions for me, is there anyone that can measure the resistance between the + and - battery terminals of a working E61, please?

Thanks!
