You say just a blank screen, but is it powering on at all? Any signs of life (lights, internal sounds, etc.) or nothing at all?

If there are any signs of life at all then you may have moved something that was not meant to be. It happens.

Since you replaced it with the original and that didn't fix it, then the problem is not likely the RAM, unless something with the new RAM damaged the device.

Have you gone back and and made sure that nothing was knocked loose? It is extremely easy to touch the wrong thing the wrong way and then nothing works.

it has the sign of life, it is working and turning on but it just doesn't has the screen, i tried plug to external monitor but still can't. is there any way to fix this issue? already changed another ram and tried but it doesn't work too.
 
Well if you just plugged in an external monitor, while it was on, then it may not have worked.

Try this...

  1. Turn the laptop off (not sleep or hibernate but off).
  2. Connect an external monitor to the laptop.
  3. Turn on the external monitor.
  4. Turn on the laptop.
NOTE: You may have to press an "external monitor" button. Could be the f4 button or a button with two monitors on it, for the external monitor to work.

If you can see fine on the external monitor, then your attached display, or the ribbon cable that connects it, are your problem.

If you can't see on the external monitor at all, or the problem occurs on the external monitor as well, then it is probably the graphics card/GPU that is the problem, which may require the motherboard be replaced.

You may also want to try hitting CTRL + SHIFT + WIN + B to try and reset your graphics driver as another possible fix.
