Hello,
I'd like to ask someone more experienced than me for advice - I'm trying to repair this Legion Y540 with a burnt mosfet (PU3001) through the PCB (damaged/shorted capacitor was also on the other side).
I am able to drill out the damaged part of the PCB, repair the surface paths and solder the components according to the available Board view data, but it is very difficult to find out if some internal paths are broken.
1) Any chance there is/will be CAD documentation available for the PCB layers for this Lenovo, such as for example for the Dell E7470 (.brd file openable in Allegro Free Physical Viewer)? (https://www.badcaps.net/forum/troubl...7-need-brd-for -dell-la-c461p)
2) Is there any theoretical chance that there are no internal paths in this particular damaged spot on the PCB?
3) I will be grateful for any suggestions.
Thank you!
