I'm working on the above laptop for someone and the backlight comes on but no picture. Customer said it use to come on once in a while after a few starts but now its just the backlight, no bios or windows logo or anything.
Works fine on external monitor. I tried reseating the cable on the lcd to no avail. I assume the power inverter works since the ccfl bulb is turning on. I ONCE got the windows logo to show up after starting it with the lid off and an external monitor. I then opened the screen and it came on but I could not reproduce that.
I'm waiting for a new LCD cable to come in but told the customer that might not work and it may be the monitor itself.
