instrument.
(1) Check whether the power switch is really on.
(2) Check whether the power is correctly connected.
(3) Check whether the fuse is burned out. If the fuse needs to be changed,

(4) Restart the instrument after finishing the above inspections.
(5) If it still persists,
(1) Check whether the probe is correctly connected to the oscilloscope and
item under test.
(2) Check whether signals are generated from the item under test (you can
connect the probe compensation signal to the problematic channel to locate

value (this problem usually occurs when probe is used).
Check whether the probe ratio of the channel complies with the attenuation ratio
of the probe.
(1) Check the trigger source: press MENU (in the trigger control area
(TRIGGER) on the front panel)  Source to check whether the trigger
source selected complies with the signal channel actually used.
(2) Check the trigger type: general signals should use "Edge" trigger and video
signal should use "Video" trigger. Only when the proper trigger type is used,
can the waveform be displayed stably.
(3) Check the trigger level: adjust the trigger level to the middle of the signal.
(4) Change the trigger holdoff setting.
Check whether the trigger mode in the trigger control area (TRIGGER) on the
front panel is "Normal" or "Single" and whether the trigger level exceeds the
waveform range. If yes, set the trigger level to the middle or set MODE to
"Auto".
Note: Pressing AUTO could automatically finish the above setting.
