hi, i just got that board

no video

so i tested the lcd with a working board. that is ok.

i resoldered the u8900 but still nothing

L8960 and L8930, L8310 and L8360 have no power at all

the machin is chiming

no PP3V3_S0GPU

in Diode mode there is almost the same value like on the good board (PP3V3_S0GPU rail)

missing GPUVCORE_EN

so where to look now?

gmux problem ?

I'm a noob, but I believe it's not possible to have image without PP3V3_S0GPU and PPVCORE_GPU neither on external nor internal screen, or is it? Do you have P3V3GPU_EN?
