I have a 54645D that has an intermittent problem where all the traces freeze or not appear (both analog and digital) about 10 seconds after cold boot or immediately after warm boot. Sometimes I can capture a waveform and that is fine but normally the traces just freeze after a few seconds. Since Keysight no longer supports this scope I am looking for a schematic to help track the problem down.
Hello don.r,

What you can do is take a look at the service guide which will have instructions on troubleshooting as well as replacing parts.
