Hi ,
Have a Toshiba Satellite laptop with a "no display" symptom.
After checking it, i can notice a very dim picture , the CCFL doesn't
lit.
After opening it , I found that the inverter had a fuse open .
Replace the fuse but after , the computer did not power up.
There was a short on the inverter boards so I replaced it with the
same model.
Now , the computer boots up , CCFL lit for a few seconds but shuts
down after.
Is is possible the the CCFL is bad also ?
Thanks for your help...
It's possible. When the image first appears, is there a pinkish hue?
Also, inspect the wires from the inverter to the CCFL carefully.

Model is P200-MB1
Only half of the CCFL lit (kind of pink) and shuts down.
That indicates the tube is old, and dying. It gets a pinkish tint
and the current rises. Replace the tube and you will have a good
display.

Does one inverter supply two tubes? And if disconnecting the problematic
tube , as a proving exercise, do you have to mitigate for overdrive to the
single tube, even for say 5 seconds of proving use?
