Hi All,
I have an M800 (10FX) where is completely dead.
The PSU is new and the power switch pulls 3.3 v dc low.
I checked the mainboard for obvious problems as burned component and leaking caps.
What I found was a liquid spill around the chipset.
I cleaned it and tried again without any luck.
Then I check the caps around the chipset and the resistance is about 35 ohm.
So I lifted a lot of the caps and the power FET with same resistance to check for faulty components.
No caps and FET seems to be faulty but the resistance lowered on the mainboard to 0-22 ohms while its hot from the heatgun (set to 350 celsius).
Does anyone have any experience with this?
My next step is to re-flow the chipset.
