Hi gurus,

This one came in without image - it turns on and all voltages are present. I reflashed the BIOS using a dump found on the internet but also with decrypting the BIOS files from HP website. I added DMI with HxD using original values from reading the SPI chip.

I also replaced the CPU (AMD BGA EM2100ICJ23HM) but still no image (rework station: FinePlacer PICO RS).

There is not 3.3V coming to the LVDS connector from UB3 mosfet (other side of motherboard near fan connector) but there is not schematic to go deeper. The mosfet is not shorted.

Any ideas?

thank you friends,
george
