Dell WD3000 back lighting issues

A friend of mine bought a Dell WD3000 and after about 1-1/2 year or so, got tired of dealing with the back lighting not working properly. (Having to turn the power on and off and reboot several times.)

So I was gifted with it. Of course, it worked just fine with me for a while then started acting silly again. Until I got tired of the routine.

I replaced both of the back light inverter boards and it seemed happy with that. (Purely coincidental I think) And now it still has the back light not coming on issues.

Is there a specific breed of chicken I'm supposed to slaughter and wave over my head to fix this?

Thanks

Jeff

If the CCFL's are bad the inverter will suffer either damage or sense over current and shut down.

There is usually a backlight on off line from the mother board to the inverter.. If the boards are marked, you can check for 2 to 5 volts on this line. If the voltage appears along with the 24v B+, you either have bad inverter boards or cranky lamps. If this voltage never appears, you can try adding a high value resistor (start with

1500 ohmsK) from the 5V line to the on off line and force the inverter on.

Dell is the only brand of LCD TV i will NOT take in for service.
