Check the BJJ power board to see if
the green and yellow LEDs are lit. If
so, one of the supply voltages is out
of range. Perform the following test:
1. Verify that the ribbon cable from
the backplane to the display is not
cut, abraded, or otherwise
mangled. Replace the cable if
damaged.
2. Use the test jacks on the front of
the BJJ board to verify the
following voltage levels:
+5V: 4.75V-5.25V
+12V: 12.43V-12.85V
VPP: 12.08V-12.12V
3. If any voltage is too high, replace
the BJJ board.
4. If any voltage is too low, either the
power board is faulty or one of the
other intelligent controller boards
is overloading the power supply.
Remove the other intelligent
controller boards one at a time; if
the voltage rises back into range,
replace the faulty board. If the
voltage remains low, replace the
power board.
5. If the problem remains, call your
local RTAC representative.
