FPV MONITOR
Not switching on.
As with the camera this may be indicative of a failed USB
charger, test it with your meter, it should output around
5.2V when plugged into a suitable USB power supply. If
not, this needs replaced with a lipo charger,
not
just a
straight through power supply from a USB cable as it
needs a dedicated charger to sense the voltage in the
battery in order to cut off supply to it.
Everything is internal from here so opening the monitor is
a must. Fortunately there are only 4 screws holding the
back on. Inside you will find the small LiPo battery as well
as access to everything else for that matter.
Again, test the voltage of battery, if not approximately 4.2
Volts when fully charged then it has probably failed and
may need replaced.
