Motherboard Does Not Power On - Component Level Repair NO POWER NO BOOT NO START.

Hi i guess i have the schematic for you from your board. EP45...but how can i get it to you. please keep up the good work i have a GA-EQ45M-S2 same issue. so i am curious if it is your south bridge. and if anybody can help me with a schematic of the EQ45 please send to me.

extra note to add: my board one day it started ok, the next day nothing anymore. the cpu doesn t have voltages

i have an GA-EQ45M board on my bench with the same symthons nothing on the poweron button but the led row if i short bl/gr. i am curious what the problem is...

it's good for the environment to fix computers instead of trashing them , we can do thousand of things with refurbishing computers : presentation in conference room or training room , gaming station , server , music player ,etc... some computer from 2006 to 2010 are even compatible with windows 10 and 11 . You have people all around the world who still perform basic functions on their computer , they don't need to watch 4K videos or play resources demanding video games

damn that was rly big iron tip for this job :)

Keep up the good work Richard.Good luck with your new chanals.

Heya, wel transiting that chip for 1 to an other board with so many pins is not easy but you proved it can be done and it was a very good idee to swap the 2 ic's. can't wait to see the next vlog on that intel chip very well done

You need a titanium tweezer from ali. Those have needle ends perfect for lifting chips.

great video hope you can fix it :)

Good morning Richard.
Got a serious problem I need some advice on, this Gigabyte Z77 UD3H REV 1.1 Motherboard I have can't not even turn on my PSU even if I short PS-ON with anything it won't but if I short PS on while it's disconnected motherboard will switch

What could be so wrong if you require a video please do let me know and il email it over.

I'm currently working on a z97 anniversary by ASRock with the exact same issue (no power when shorting pwswitch jumper, green to black provides power while jumpered, etc.) I noticed a blown fuse near the power switch circuit and there was a capacitor missing near the CPU socket. Other than these two issues there didn't seem to be anything else noticeable occuring. I'm wondering now if the sio chip is the source of the issues but I'm currently at a loss.

sorry but i wasnt paying a lot of attention watching parts of this video, but did you get the exact SIO chip from the same model of motherboard? Those SIO are programmable, and for that to work, you either have to reprogram the SIO or get it from the exact motherboard model. Good troubleshooting though, good job!

I love your humble approach to diagnosing. Your electronics knowledge and debugging skills are captivating.

I was just working on my RSMRST, thinking it was shorted with 20 ohm. Looks like it is low when off and goes 5V when started.
Schematic-X is where I found my boardview.
I've been looking at GPU repairs and they have logic chips that have to have the correct signal before the chipset will allow a start. Could it be one of those.

hi LER...those are small components...may i request a video on a diy of a microscope using an old camera lens and a webcam. thanks. Keep Safe.
