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

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.
