Aspire 5102 WLMi display replacement

\015 Slept on my Aspire BY ACCIDENT cracked display. After installing new one,my laptop will not boot with video? cable plugged into inverter. When it doesboot, screen is black.

Screen never lit and laptop only powered on with inverter unplugged. No image ever on any screen.Anything we missed? It does work on external monitor.Hello and thanks.Joe Dirbasm[email protected]\015

Answers :

Sounds like an inverter problem. If the power supply is internal replace the capacitors coming out of the voltage regulators. These are usually 1000mf and/or 470mf. If that doesn't do the trick look up the numbers on the 8-pin chips that drive the secondary transformers on the inverter to see if they are getting the right voltages.
Good Luck!
