Hi Kevin:
Just a guess. If line triggering does that there may be a problem with the
power transformer.
Use an Ohm meter to locate the transformer terminals for the AC line and then check from one of those to all the other
terminals.
I suspect there's a short in the transformer.
Look at U502 to see of it's burned up.
Have Fun,
Brooke Clarke

Hello,
Thanks to Brooke's excellent web page [1] on getting the DG535
80 MHz clock working, I was able to fix the "Ext Clk Err" on
a DG535. Everything on the front panel seems to work.
However, triggering does not work. I can't get a trigger to
occur in any triggering mode. Setting the triggering mode to
'Line' causes a loud 120 Hz vibration from the rear of the device.
I've checked voltages from all of regulators mentioned in
the manual, and they seem fine.
I wonder if someone has an idea about helping the DG535
trigger.
Thanks,
Kevin
