3,3V short circuit?

Fri Jul 12, 2013 6:01 pm

Hi,

one of my Raspberry was about half a year out of use. Now i wanted to use it in a little project.
When i connect the powered USB Hub the red LED shines just a little bit. Connected to another power supply i saw that the 5V supply voltage drops to around 2,3V while the current is around 1A (current limit of the power supply) while absolutely nothing is connected to the Pi (not even the SD card). I felt that the 3,3V voltage regulator becomes really warm. So i think there is a short circuit between 3,3V and GND somewhere on the board.

I don't believe that theres any chance to fix it, but does someone have an idea?

Thanks

There is a miniscule possibility that an electrolytic across the 3v3 rail has gone short-circuit. That could be replaced. But I fear this RPi has followed the path of the MPFC parrot.
