Need schematics of HP 15-CC057CL touch screen laptop.

Try to fix the problem i can hear the laptop boots and windows start sound up but with white screen. isolated the problem by replacing the lvds and lcd screen with service unit. but still with white screen. connecting an external monitor normal windows screen. i found the problem somewhere in lvds no power to the lcd screen burned component might be a control ic to the mosfet.

As this is for LCD, my guess would be that someone disconnected/reconnected it while power was still applied to the board. Or the cable became loose by itself. Or it is damaged inside the hinge.
If it doesn't fail again, good, if it does then you'll have to look around LCD connector/cable, maybe panel.
