I’ve got a Inspiron 1545 laptop I’m working on. Looked to be just a simple LCD swap as he cracked the old one. Got in the new LCD and cannot get any video to the new LCD. I hookup external monitor and can see windows boot up and work just fine. but try to go back to the new LCD I get nothing. I changed the video cable wih a new one also and still have the same problem. This PC doesn’t look to have any inverter to change so what should I do next? Any suggestions? Thank you for you help in advance.
