Hi,
I just bought a used SB2 and the previous owner connect it with the wrong power supply...(13v instead of 5V)
The SB2 still power on,
but the display get on for a second or two and turn off immediately.
After more further investigations I found one damaged IC.
The defective IC is part of the PC Board used for the fluorescent display, the part number is not readable but the part number is identified as U5,
the part is manufactured by Fairchild.
Any help will be appreciated.
