Hi,guys i'm working on a DS1052E Oscilloscope
the problem is that any DC signal applied to the input of the scope is inverted eg:if i put 5 Volts DC than the scope displays a -5 Volt DC signal.I have done a fuctional checks on the other functions and it's all good it's just this one problem,don't have a service manual to start with.Can anyone help me on this.Were should i start,probaly from the input
