It could be a small electronic component that's buggy, causing the power circuit to have intermittent supply. really hard to say. Just guessing at this stage. I'm fairly familiar with electronics, but not DSLR electronics![]()
i had this problem recently.. but its not because the battery or my camera. it is because of the desktop charger that is causing the problem. Before i switch on, I already put the battery in.. some how it could charge for a while but it ended quite quickly.. I had to put in the battery after i switch one about 3-4 secs after its switch on then it will function properly..
not sure about the above mentioned problem..
