Can you be heard OK when using the headphones with the microphone attachment plugged into the headset jack or when using the phone in loudspeaker mode?

If you can't be heard at all then there is a problem on the systemboard

If you can't be heard at all then there is a problem on the systemboard affecting the transmission circuit.

If you can be heard when using these two methods, then the problem is still associated with the microphone
Did you clean the phone properly using Isopropyl Alcohol 99%+ to ensure that any and all corrosion was removed e.g. disconnect and clean all flex cable ends and connectors, remove any shield covering components and clean under them as well etc.
