1) Try shorting the body of the input BNC socket to the ring at its base, something will happen. The idea is that if you use an X10 probe with a shorting clip fitted the V/div markings will be correct for the probe.

Most if not all of the other faults are probably due to the 5500uF cap that smooths the 8.5 Volt supply rail.
