Hi,

This machine has image, but no backlight.

I replaced the LCD connector to restore image

Backlight is on pins 38,39,40 (image)

In the schematic, those 3 pins are the same line

In the image, pins 38, and 39 are connected to a pad, however there is a gap between the pad and the wire on the motherboard.

Does the signal go out pad 40? Or do I have a pulled pad.

Thank you

Please ignore previous...

I just repaired some of the backlight circuit by replacing the fuse and a resistor. Everything seems to have correct voltage until L9701. I'm not getting 50 Volts from there.

Replace L9701?

Is there image? Did a PRAM reset?
What is actual voltage on L9701?
It is never the coil.....

I reset my Pram, not sure I did it right (picture)



After resetting the PRAM. It won't turn on with a screen plugged in. I saw and heard electricity at the lcd connector

There was an image, no backlight. Not sure now. At L9701 it was 12.5V or whatever was correct before the coil.

Burned LCD cable? Check for shorts on LCD connector with LCD plugged in.
