I told a friend I would fix her laptop for her, I ordered the part and it got here. Did the tear down and test and the screen didn’t work. So I ordered the whole lcd/digitizer and assembly. I finally get it after a month and test it. The splash screen started. I reassemble and it doesn’t flash the screen anymore. Did I hoop it somehow? Do I need to reset the power on it? Any ideas?
Did you follow ESD (static electricity) precautions when you were working on it? If not, you may have damaged it. There are also many other things that can go wrong, most notably connectors damaged or not properly connected. Hard to say what might have happened.
