Solved! Asus laptop unable to boot, blackscreen and no brand logo

[sutenditeten]

Hi, I tried to change my Asus N46V HDD to SSD. But it cannot boot successfully once I changed the boot priority. The worse problem is the asus logo is not appeared, so I can’t change the booting configurations anymore.
Have tried these steps but none of them work:
- reinstall RAM
- hold power button for a minute while no power and battery
- remove and install CMOS battery
- boot without disk

When I tried to turn on the PC, only power and battery indicator on. Cap locks power is off.

Would someone please give me an advice if there’s anything I can do to fix this?

try to look closer from a different angle maybe you can see anything on the screen. backlight issue
it can be also graphics chip issue or 5v power rail problem
