Removing the Inverters
When replacing inverters, first replace the board(s), and then test the unit. If the TV still does not work, replace the
inverter cable(s). Inverters are spared as a pair (except for the 32-inch model), so you should replace both. The
inverters are NOT the same – there is a Master and a Slave. If you are facing the back of the unit, the Master inverter
is on the left side above the speaker marked L (for left).
When plugging inverter cables into the power supply, the Master inverter cable outboard and the Slave cable is
inboard. You have to remove the main bracket, but do not have to remove the power supply or main board to remove
the inverters.
Note: Inverter board cabling differs based on model.
LT 3200 Inverter Removal
Note: Model LT3200 has only one inverter.
1 Remove the six screws that secure the inverter cover to the unit, and then lift the cover up and out of the unit.
2 Disconnect the six cables from the connectors on the rear of the inverter board and the remaining cable from the
connector on the front of the board.
Note: The connectors have a catch you must push down before removing the cable.
3 Lift the inverter board up and off the unit.
