Troubleshooting
So now it happened. VISIO 24 does not work as expected and you are clueless if
it is broken. Very often, a small reason can cause a big problem, which can be
resolved easily. So please read the following checklist and try to find out what is
wrong. If this does not help, please switch VISIO 24 off, unplug the power cable
from mains and contact our service department.
Display and lights remain dark
Please try to switch VISIO on again. If this does not help, make sure power sup-
ply is connected to both the VISIO and wall outlet and that wall outlet is live. You
may want to connect another device to the wall outlet to check.
Are all plugs seated properly in their sockets?
Only display remains dark, lights are on
Is the light in the display
’s lower right edge on? Is it red?
If not, switch VISIO 24 off and on again or press the sensor button in lower right
edge of display. Best you touch the edge and move your finger leftwards. Now
the light should be on and redd.
If not, please check if power cable in back of display is seated properly. At VISIO
24, the short power supply cable for the display comes out of the camera housing
behind the display.
