Sounds like an input amplifier is fried due to overvoltage. If it was a mechanical short it would be near zero ohms, but you have a short through a semiconductor junction.

We will need some more info.
• What make and model is it?
• Was there different impedance before?
• Are you sure it is not 1 MΩ???
