Here's the solution for Nokia 6760 slide for Insert sim card problem or the phone won't recognize or detect any sim card inserted to it. We track down the simcard pin connection as showed on the image below. We can use it for an ease of troubleshooting, if the insert sim card error problem occurred on the device.
In Nokia 6760 slide there is no EMI filter IC used or mounted on the PCB board, the SIM card signals were feeds in and out directly to the power IC (AVILMA), but we can still trace down the SIM card supply voltage (VSIM), DATA and Ground pins on some components.
Here's some hints on how to troubleshoot and fix the Nokia 6760 slide Insert sim card problem:
1. Check and ensure that the sim card inserted is still working or try to use another one.
2. Visually check the sim card pin connector surroundings, clean if an oxidation build up spotted.
3. Trace and check the VSIM, GROUND and DATA down to the components where it is being connected.
4. If it doesn't work, the next option is to re-hot, rework or replace the power IC.
Enjoy!
