My friend's All in One screen is Flashing and is distorted.

Hello, one day my friends All in one was working just fine.  The Next morning It just kept showing a black screen  tried a few times through out the day.

Decided to do research, and tried  New Ram, and Reseting Bios. even checked the Lcd cable and inveter cable and board and  still Nothing Displayed on the Computer Screen.

So I bought a new motherboard to see if this will resolve the issue.  748363-002.

So after installing the New Motherboard. I see an Imagine on the screen, However the Screen is Blinking pretty rapidly and is distorted.

So I decided to reset the Bios and then change the ram, also checked the Lcd cable everything is sitting as it should but the problem persists.

Computer gets to the log in screen, yet is not working as intended. With all the Flashing and Distortions.  Now had this been a normal computer Id try an external monitor, however this computer does not have any video ports on it, just the built in screen.

If anyone else can offer ideas Id apperciate it. Think my Next option is to try another Lcd Cable.
