Haier W66 Tongfang V100 N211 BOM
-
Hello everyone,
I am troubleshooting a Schenker XMG NEO 17 (M22), which is based on a Tongfang chassis (likely GMxRGxx series, 2022 model). Specs: AMD Ryzen 9 6900HX / NVIDIA RTX 3080 Ti (16GB).
The Incident: The original LCD panel developed an internal short circuit (measured shorts across almost all rails on the panel side). This caused a catastrophic failure in the backlight circuit on the motherboard:- The backlight fuse was blown.
- The P-Channel MOSFET which switches the 19.5V backlight rail was destroyed. Measured nearly 0 Ohm between Source and Gate and 240 Ohm
