G550: Display flickers / distorts. External display fine.

I have a weird issue with my G550 (which is out of warranty).  The screen flickers and distorts (fuzzy colours around objects on the screen).   If I flex the case in a certain way the problem goes away, it's hard to describe but if I apply pressure in a certain direction to the back left of the case it solves the issue... but as soon as I stop applying pressure it goes away.  I'm thinking it's a loose connection somewhere between the GPU and the display, but I'm not entirely sure where to look.  If I plugin in external displays they work fine, no flickering or distortion at all.

hi deicist,

Welcome to the Lenovo Community.
If the LCD screen flickers when you open or close the lid or if tilt the LCD screen on a certain angle then the problem lies on the LVDS or LCD cable (possibly got worn out by opening/closing the lid alot of times). If you're interested in fixing it, you can get spare parts here:

Caution: Please be careful in disassembling your PC as it may contain sensitive parts.

Hope this helps.
