Screen worked for 10 seconds then died. Changed invertor as the backlight wasn't working but that didn't fix it so tried to check the voltages on the invertor input, should see 12v on one of the pins but wasn't there so presumed the invertor wasn't working because of lack of power. Took the middle cover off and I could see what looked like charring by the video connector but that could have been the remnants of the drink dried up. The invertor power is fed through the video connector and I've no hope of fixing anything their so what I want to do is to provide an alternative 12v to the invertor to see if that will make it work. Problem is that I cannot find anywhere a diagram that shows which if the 6 pins should have the 12v. Would anyone out there have any idea where to get such a pin-out from or a wiring diagram for the laptop? The inverter has a number of different partnumbers, LX.ADF05.057, LX.ADF05.100, LX.ADF05.108, LX.ADF0J.012, LX.ADF0J.013, LX.ADF0J.016, LX.ADF0J.075, LX.ADH0J.007, LX.ADH0J.008, LX.ADH0J.035.

Splash Bios screen on start up, extremely dim display, falsh light can see OS running. When i run a magnet across the top of the keyboard the screen lights up, so i think it is a problem with the magnetic lid switch. This switch is located right beside the biggest magnet in the laptop, the hard drive, clever. I am trying to find a way to disable this feature, not sure if it can be done.

Most likely you have one of the following: 1. Bad connection. 2. Failed video cable. 3. Failed LCD screen. Check the connection first. Tim,

It's possible that the video cable got disconnected. If the connector is half way out, push it in and test the laptop.

My Toshiba Satellite's lcd stopped working. I tested by attaching an external monitor to it and the display works. I couldn't figure out if it was the back light, lcd, or inverter. I've shinned a flashlight on the lcd and cannot see anything. Though when I dim the lights, I see the lcd lite up. Does anyone have any ideas? thanks much. Tim. I believe I may have the same problem.

The lcd screen is dark, but I do see a back light.

It’s not very clear if the backlight works or not?
