supply problem prior to the
failure or the Power Supply

power cord is faulty, or the
power supply is faulty. Make sure your power source is
reliable. Try another power cord.

The standard Windows
operating system desktop is
displayed rather than the
expected applications of the
iVDR AppCenter. AppCenter is minimized or
AppCenter is not running. Maximize AppCenter or open
the
AppCenter icon on the
Windows desktop.
The Windows desktop appears
around the edges of AppCenter
and scrolls as the cursor moves
to edge locations. Transport
controls are displayed. The display properties are set to
the wrong resolution. Make sure the display properties
area set to 640 X 480. This is a
Windows operating system
display setting.
