Help needed for dead backlight.
The screen is ok, I can see the scren contents with reflected light.
Aslo can get the backlight to flash momentarily when the Fn+F6 buttons are pressed.
Check the luminance Tube If it is ok then check the power up circuit of tube,check flexible cable connected from motherboard to the power up circuit, check for dry solder in the circuit. But be careful,don't touch or handle the power up circut of tube while the laptop power is turn on because of step up high voltage generated in that circuit.
