After tear down for cleaning my LCD stop working, my LED's 1, 2, 4 are on when computer is turn on, and NO LCD, could it be the video card?, also, before tear down the LCD was freezing at times with vertical lines and I had to shut down and turn on to make it work, maybe this is indicative of a bad video card, also I did install new thermal paste where it was needed the old one was very dry.
Thanks, Ro

It is possibly a screen connector stretched or ripped but first try replugging the screen to the logic board.
