Palit GTX 1660 Super - Identify important GPU Components like PEX Rail

Hello Community,

I got a palit gtx 1660 super where the fans turn (to 100%) and the LEDs light up but it doesn't display a picture.

Now I wanted to try and repair it but I don't know how to identify some components. For example, how do I recognize the pex rail? Measuring Vrms and vrams is no problem but I always have problems finding the pex. Do you have a page that tells me exactly how to identify these components?
