Start with a careful visual check of all cable links. If the LCD's are
not working, make sure that the power is reaching the computer
and all peripherals.
Note: Switch off the computer and check all cable
i
links. If the computer is connected to peripherals,
check also the plug connections of all cables. Do not
arbitrarily swap the cables between various units,
even if they appear to be precisely the same. The pin
assignments of the cables are likely to be different.
Once you have ascertained that the power supply is
not at fault and all connections are intact, switch on the
computer again.
