It chimes with backlight. no image. i also have tried external display and nothing, even with LCD cable unplug.
PPvcore_gpu = 0.9v
L8360 = 0v (should be 1.36v) - resistance to GND on L8360 is 172 ohms
PP3V3_S0GPU = 3.3v
GPUVcore_en = 3.3v
P3V3GPU_EN = 3.3v
PPVIN_S5_HS_GPU_ISNS = 12.58v
I've already replaced U8900, I've reflowed the old and its still same,
yes. there seems to be USB activity. I've tried other bios from a donor board for testing and its the same.
