U9420 Had Corrosion. Notebook was not powering on after ultrasonic. Powers up no back light. No signs of corresion anywhere else. Pin 1 on connector looks red but soldered on c9000 is reading at 54v

At this point you need a known good LCD. This is why you keep a few cracked but working assemblies for testing. Make sure the connector on the board is good before plugging in your good LCD or the cable may burn again.
