What causes a red light on an TB Wood Etrac XFC 1001 inverter and the motor will not start Is there an internal fuse Do I need 3 phase for the input


Is that red light flashing or continous lighting? You do not need 3 phase input for that model. Do you have the input wiring diagram? If the red light is flashing maybe the emergency stop input is active. If the red light is on continously then it maybe in stop mode or torque limit, ask electrician to check the wiring.

I have an F16 fault on a TB Woods Etrac drive. Can u plz suggest me what should do.


If it is readable copy the data off immediately, if not you need to take it to a data recovery service such as ERS Data Recovery at 1.888.248.3148 What yo depends on how important the data is.

How can I fix Toughbook


If you screen was dimming on your Toughbook, then try to
attach an external VGA monitor when the Toughbook is
turned off, then power on the external monitor,
then power-on the external screen.

If the external screen works, then you may have a bad
inverter if you TB is 2007 or before.

If the TB is 2008 or 2009 or later, then probably your screen
is NOT LCD with an inverter but instead LED. Which means
that you have to replace the entire LED screen.

Good Luck!

Blower motor intermittent failure


Change your blower motor resistor, common problem, where certain speeds will work intermittently and eventually complete failure. Located under the dash behind the glovebox. My #5 just quit working, I will be doing this tomorrow. My last TB, same thing happened. My neighbors TB same problem, only her female connector was melted that plugs into the resistor. My current TB is melted too, so I need to replace the connector and the resistor. This problem is so common in TB's and Envoys, it should be a recall.

The fault is associated with drain out (pump blocked or restricted in some way). Try to clean it or contact Hotpoint support

First if you can, try the monitor with other PC first to make sure it is not the PC problem.

If it behaves in the same fashion, then most probably has dying power supply due to bad DC filter caps, just see the top side of the caps to ensure it has not bulged up distorted.See the images bellow

Then there is the logic board. Plug the monitor in but do not activate the power switch so the backlight inverter circuits will be off. Check the 5vdc and the 12~24vdc to make sure they are OK. They should be tested with the load, you can use 6V 1A (6watts) lamp for the 5vdc, and car lamps such as 1157 (12v 8watts lo/26watts high) turn signal brake lamp using high filament connection for testing the 12~18vdc (or use two 1157 in series for 19~24vdc) for the backlight inverter circuits.
If the power supplies are working, the output voltages should be steady at the rated voltages. The power supply will go into shut down if it detects too much current draw due to false in the power supply or short circuits in the backlight inverter or in the logic board.

The backlight inverter circuits:
It takes the 12~24vdc and converts it to high frequency AC to drive the inverter transformers CCFL (Cold Cathode Fluorescent Lamp) assemblies. The transformers will drive the CCFL by applying the start up voltage (around 1500~2000v), when the CCFL start conducting, the voltage will drop down to about 500~800v.
The inverter has detection circuits to detect open circuit if the lamp is not attached or does not fire up after the start up voltage is applied, it will go into shut down. It will also shut down if the lamps draw too much current due to ages (when lamp gets old it will draw more current).
The inverter gets two signals from the logic board, one is the backlight ON/OFF signal, the other one is the Dimming signal for the lamps.
Common problems:
Bad filter caps, resonant caps (in the inverter output circuits), blown transistors/IC, shorted or open transformer winding.

If you are confident with your skill then go ahead else go to an authorized outlet for repairing
Do write back if you face any difficulty while working on the monitor

If you put the old inverter back on and the system works, I'd suspect the inverter is bad. If the system is still a no post after putting on the old inverter, then you may have a motherboard problem now.
