They replaced the lense in front of the IR sensor and removed some internal label near the sensor (I was told it was interfering with the sensor). I am not sure what else they did - I am travelling at the moment - will ask the repair shop and get the bulletin number. Panasonic sent a kit to the repair shop for this problem. They called me to tell me the repair would be delayed by a couple of days until the kit was received by the shop. All is fine now.
