Is there anyone who can help me or guide me with this Motherboard repair...?
I have squeezed out all of my brain capabilities, unfortunately i have no enough knowledge for this, but i want to learn...
Ok, i will explain what is it and how it is, and if someone can help, i will gladly buy this membership because i have no other place to learn this...
I didn't find schematic or boardview so i need to work in "dark"...
Water damage, one of the chips was in short, but there was some strange coding on top of the chip so i was doing reverse ingenering to find out after about a month the name of that chip, that was actually 3.3v_alw. I have replaced and now something taking 144ma from it...With thermal camera i have found that only EC is little warmer (about 10°C warmer then rest of the board)...PD chip wont turn on 20v, it stays on 5v...The circuit with two mosfets, coil, two mosfets gives 16.7v on the main rail...Bios chip for the PD controller has 1.8v...
What info should i give or what to do next...
Please help...
