Hi @bbypete128
Some things you can try, I have a feeling the LVDS cable might be degrading or getting loose, I had encountered this weird issues on several laptops I worked with.
If it is under warranty, send in for repairs.
Else what I will try is to reseat the LVDS cable from the mainboard to the LCD Panel.
In most case it will fix the issues.
To confirm your graphic card is going well,
Here are some steps I will also do,
1. Update Graphic card drivers
2. test out with external display.
