[NConstantinou]

Hi all

i have the lenovo it powers on but no display.
I measured the voltage q9 by lcd connector and i do have 3.3v.
I connected external monitor by removing lcd connector from board but nothing.
Does anyone has any suggestions!!!

Thanks

The absence of video can be due to many factors. Connect POSTCARD and see at which post the stop is.

if it has a ram module try to re seat it or test it with known good ram.. check all power rails.. 5v and 3.3v ALW.. bios ic voltage.. rtc battery.
