Default LeCroy 9400 malfunction

Hi,

has anyone any experience with the LeCroy 9400 scope, especially concerning typical failures & fixes?

I bought one for a ridiculously low amount in an antique shop, but one of the channels is defective. The input signal gets to the ADC board intact but the ADC only picks up noise and hum, as if its input were floating. I haven't been able to pinpoint the failure any more than this.

Kenneth

Check for bad connections.
