Hello Burns447,
May you specify your model and the describe more about the issue scenario?
Thank you.
The model number is C434T. It worked great and the screen still works, but now it has vertical lines across it?
Hello Burns447,
the grey lines were there all the time or just flickering from time to time?
And the issue happen out of a sudden or was there any update or modification?
May we have a picture of the issue?
Thank you.
