It was working without problem. I've just forget it a night and it stay work. After this, it no longer boot but heat a lot... This is not the SD... And the cable work perfectly. But the 3.3V pin is at 1.80V. Does everyone have the same problem ? How to solve it ?
I don't know how you're measuring that, but it is well beyond the maximum recommended operating temperature of 85°C and implies the SoC is now garbage.
Does everyone have the same problem ?
No, I've never seen one get above 55-60°C, and that's by maxing the processor core out for a while. In fact except for the model 3, I don't think I've seen one exceed the bottom end of that range.
But the 3.3V pin is at 1.80V.
Also not good. As a random, unexpert guess, perhaps the 3.3V regulator is busted (you did not say which part on the board was getting that hot). That cannot be fixed.
How to solve it ?
I think you are out of luck. Although I doubt it is the case, you could leave it unplugged for a few days on the chance that it is the main polyfuse that's heating up (but I do not think the symptoms of that would be as you describe).
