I have an Odyssey Neo G9 that I was working on for a separate issue. After removing the motherboard and putting it back a few times I noticed that the lights on the display have stopped turning on altogether. I was able to determine that when the middle section for the backlights is disconnected, then the left and right side turn on, indicating that the fault is obviously in that area.

After closely inspecting the mainboard I noticed that on the back side of it a few capacitors have been partially moved, one fully knocked off. I replaced the missing one with a new cap with the same...

Nevermind, I checked again and was able to find the faintest bit of glow on one of the cpu mosfets :/ checked like 10 times before and could not notice it somehow. I do appreciate all your help though.

I did test the mosfets as instructed, though I do still mix up the names of all the parts. The second one when measured against ground does appear shorted but when measured by itself seems fine. What would be the best way for me to try to isolate the faulty part? I have a voltage injection tool and a thermal...

I do not have a schematic from the forum unfortunately. I measured the two mosfets near the DCin and they do not appear to be shorted as all the measurements are in the hundred kohms or higher. I'm not sure how how to identify the charging IC for certain but I believe it might be the 6s30a chip. I have found some shorted capacitors close to where the mosfets are, but when I try to inject voltage the only thing that gets warm is whatever I'm injecting into.

Hi,

I am working on an Asus ROG laptop repair. I was able to find that there is a short on the motherboard, and the 20 volts from the charger only gets to the first mosfet before disappearing.

When looking around with a thermal camera, I noticed the chip marked "14C" in the picture was getting warm. Nothing else was receiving heat.

I found a boardview diagram and schematic for a motherboard that looks nearly identical, that has the same component. This appears to be marked as "AC Short Protection" with a value of 13.7KOhms.
