Feeling a bit silly!
Feeling a bit silly having to ask this but im stumped!
So I have a toshbia satalie a350 (I believe is the model)
I get a problem with intermitent vertical coloured lines. Ocasionaly they are black and white.
Ive stripped the lap top down, checked the connection, the fan, the inverter etc. Reinstalled the vid drivers, loaded an alternate OS (Ubuntu) restored the system to factory etc. I cant figure out the problem. When I connect to an external moitor I get zero issues with screen. Even if the laptop screen goes then the image on the external monitor is fine. Apart from replacing the actual screen im lost.
