Laptop Screen flickering...

Couple weeks ago, the lcd screen on my laptop (Toshiba Satellite M40X) started flickering, put usually a tap on the screen would stop it... but now the flickering won't stop, and sometimes the screen freezes in a flickering position and so all in all, it's useless right now...

Is there any way to fix this problem??? I really don't have any money to spend,
i have taken apart my laptop before so i think i can take apart the lcd if there is any way to replace it...

Thanks for the help!

 

Also, i'm thinkin of reseating the connection cable i dunno if that would help... i dont wanna open the laptop just to find out that flickring has nothin to do with reseating... If that would help, on this diagram, do i reseat the cable pointed with the red arrow on the top in the middle... I dunno what the 2 skinny cables that go into the screen on the left

The 2 skinny cables are the antenna for your internal WiFi card (usually). Go ahead and try to reseat everything that can be reseated. If tapping the LCD used to stop the flickering, then chances are something is just loose, and after weeks of tapping, it has now become loose to the point of barely connecting. Have you tried to hook up an 'external' monitor to the VGA port? If so, does that flicker? If it does, you probably have a serious MB problem. If not, the worst case scenario is probably a complete LCD replacement; used ones can be had for $150 or less on EBay....
