Hello, I flashed everything 16MB, 8MB and 1MB, cleaned SIO and switched from 16 to 8GB ram and still no display, laptop turns on but stays on 0,9A.
Can you please try to clear ME? Or do you think its hardware fault?

Everything seems ok. All voltages present, resistances seem ok; I even swapped 16 and 8 chips itself, no result. Thank you for your help
