My nikon Coolpix l31 is turning off to prevent overheating in under 30 seconds of having turned it on. This started about a week after I got it. Haven’t used it much since, got it about 2 years ago.
the likely answer is one of two things. A short on the board, or a bad internal resistance of the battery. If you replace the battery, and it doesnt fix the issue, the most likely scenario is that a board level short is drawing too much current. replacing a logic board is usually not worth the cost of the repair, and i would suggest replacing the device at that point.
