I just replaced the top LCD screen and after putting it back together it wont turn on. When I press the power button all I get is the 3D comes on then goes off quickly. The motherboard seems to be getting power but just wont turn on. HELP!!!!!
Take it to a dark room and turn it on. Watch the screens carefully. See if either of them flash. If the bottom screen flashes then there is probably a problem with the top screen. If the top screen flashes then there is probably a problem with the bottom screen. If no screens flash then there is probably a problem with the speaker ribbons somewhere. This test is not 100% but most of the time it will lead you to the problem. I hope this helps.
