To help you solve commonly encountered problems we have listed some
typical issues with their respective solutions. If the problems persist contact
RIGOL and prepare your device information (System  Information 
System Info).
1. The screen still dark (no display) after power on:
(1) Check if the fan is running:
—
If running, the connection of the internal screen cable may be
loose.
—
If not, the instrument has failed to power up, please refer to step (2)
or (3).
(2) If the battery (China only) is used for power supply:
—
Check whether the battery is in good condition and whether it is
correctly installed.
—
Check whether the battery status indicator at the front panel
goes on; if not, the battery contains no electricity and please
charge the battery.
(3) If AC power is used for power supply:
—
Check if the power supply has been connected correctly and power
switch has been turned on.

Check if the power fuse is burned. If a new fuse needs to be
installed, please select one with these specifications: 250V AC, T2A;
5 mm×20 mm.
