Canon eos 600d was bought 18 months ago. I live and take photos in Thailand (hot, but not extremely hot). I take a lot of photos. Around 2 months ago when I was taking photos on a trip, suddenly the camera stopped working. It looked like the battery is dead (wasn't dead, still 60 %). I changed the battery, tried both a couple of times - still not working. The same next day. and after 3 days it was ok. I took photos many times (maybe 3,000 pictures). But sometimes I had to take the battery out and in, after 2-3 times the camera was on. And now it's not working again. I think it is final. I cleaned, tried different "tricks", failed. ??? It looks like problems with power, maybe ""wires" connection. What do you think?
