White Bars on Laptop Screen

Recommended Posts

One day some white bars showed up on my Dell Inspiron N7110 laptop. Now I crowd-source my diagnosis.
- white bars show up in BIOS/Diagnostics
- they are not shown on external display nor screen captures
- funny thing: they're not "covering" the screen, rather the screen is "split" at these areas (see video)
- screen is actually being pushed off the side!
- reseating LCD cable at both ends - problem persists
- praying

This fault is usually due to a poor connection made by the ribbon cable.  

Sometimes the fault will show as two vertical white lines. You can also get horizontal lines as well. 

Check the seating of the ribbon cable connectors between the display panel and the motherboard.
