LeCroy 9400 Digital Oscilloscope’s ADC cracks

LeCroy 9400 Digital Oscilloscope's ADC cracked

The ADC for this oscilloscope is cracked and malfunctioning – only the upper 4 bits work.  The screws shown that hold the heatsink on the reverse side of the board were loose and probably caused it to overheat and eventually crack.  Credit: http://www.flickr.com/photos/imager/ / CC BY-NC 2.0
