Hi friends, I have a case - Dell Optiplex 9020 AIO ipplp-az revA00,PCH = SR137, CPU = I5-4670S. After power on, system like boot (led hdd blinking) but no display.
When I press button power + menu, dell test dispaly ok, on screen green, red, blue & another test pictures but normal start display black.
I programm new bios but no sukcess.
I moved old bios ME Region to new bios still bad, I tested RAM seems ok.
I have not found a diagram, which pins of the display connector are transmit for identification?
no screen on lvds or hdmi or vga
the bios file I used :
I used another bios but the same effect.
Both bios, before I move ME Region an error code appears 3 & 7 flashes orange, on the dell website, the identification of this error is RAM configuration or RAM replacement.
i tried to use other ram error the same.
If i move ME Region from old bios the computer returns to its original state.
