Hi there!

This board had water damage. Not too bad. Mostly around LCD connector area. Gave it an ultrasonic bath and replaced LCD connector and backlight IC because some pads were corroded.
It is switching on and working fine on the external monitor but has no image on LCD.

Checked LCD connector traces, seem to be good.
Pin 2, 3 - 0V
Pin 4 - 3.3V

U9000
pin 2, 3 - 3.3V
pin 1 0 - 0V
[in 4, 5 - 0V

Please suggest how to proceed.

Thanks!

Well well well. I gave it another ultrasonic wash to clean off the sitcky icky icky flux from the connector after the replacement and everything started working again.

Thanks for your help anyway!

Oh no spoken to soon. Reassembled everything back and not working again. Checked the connector under microscope and the plastic looks a bit too melted. Will replace again :S
