3GS is not have LCD IC.
LCD connected via 3 L-filters to processor.

The problem is in the chip. Use a hot air soldering iron and solved the problem.

Problem in your mind if you think that 3GS have video chip.
Touchscreen IC is located on the same place where 3G have video IC and serial memory IC for the video.

There are two WHITE SCREEN issues:
1 = press ,Up volume,drop the silence button to silence,home button and press power button at the same time till you see Apple Logo.

2 = Open your device,check all the pins of the lcd connector on pcb,replace it if possible.Google for the pic solution,somewhere on the net.

Check next components.
Resold or replace.
Also problem may be with Power Manager if "WLED1-OUT" signal is absent on pin.6 .

P.S. pin.6 of PM IC - accordingly pin.1 of connector LCD.
