VGC chip is bad - need a new logic board OR you might be able to have the VGC replaced ( expensive).

Are you sure that the VGC is Borken?

Because Why is the backlight not working too?

Could it be something Else?

I saw an onlineshop they repair exaclty this Problem for around 100$

So my Hope is that it is something Else.
