When its plugged, the keyboard is lit, but no picture.

@miamoreh …. typically, when there is no display but power to the unit, it is caused by either a frozen bios/smc, a loose or shorted connector/component on the display driver circuit, or a bad screen. to troubleshoot, start with the easiest. remove the battery, open the device, remove the cmos battery and short the positive and negative terminals. while you are there… disconnect your display connector and reseat. button up the device enought o be safe while powering back on to see if this clears the issue. if not, you will want to start trouble shooting the display circuit. looking for burnt marks or components. taking measurements against a schematic is the best course of action.
