I have lenovo G530 Laptop.

In the warranty period, the mother board had gone bad. There was no display.

The mother board got replaced. Now a new prob has started. SHAKY LAPTOP SCREEN. One of my friend, replugged the video card on the suspicion that it was not properly fixed. The prob is still there.

I have the video of the shaky screen but I don't know how to upload it.

Can anyone let me know how to fix it??

If it s kind of distortion ,I had same problem in a F Siemens Esprimo ,the problem is the "flat" connecting mother board and LCD screen ,it needs to be replaced ,to figure this out do :
Connect to outside monitor ,if the problem exists on it then the VGA adapter needs replacement
If there were no problem in the outside screen ,then the problem is in the flat connection
