Thank you very much for your reply.
I have bought it today. I switch it on and then asked me to enter the date and the time. After a while, probably 5 minutes, I saw in the LCD a message "High camera temprature" and the camera went off.
After a while I tried to switch it again and I got again the same message.
I took out the battery and charged it and after 3 hours the led on the charger became green, meaning full charge. I put back the battery and I switch it on. The camera after a few seconds saw me the same mesage and went off. After that it is refusing to start, unless you take out the battery and you re-inserted again. Of course after a few seconds goes of due to the "High camera temperature".
All proposals are welcome.
Thanks a lot in advance.
