It show different colored vertical lines. These keep on changing, when I turn display down and again up. Sometime it get fixed by this turning of display down & up. Sometime half display work properly with vertical lines on left half display. Someone if I play video, then it gets fixed in 20-30min. It also get fixed when I hold display support with some pressure(where display and laptop are connected). If i leave laptop on with these lines, the display comes for 3-5sec and again vertical lines are displayed. But the display work done after it get fixed. So what is the problem?

Hello @Ankit9,

Welcome to the HP Forums! I understand from your post that you are having an issue with vertical lines on the display of your Pavilion G4 notebook.

From your description it sounds like there may be a loose connection since the issue changes depending on the positioning of the display, however, you can try following the documents for Video playback issues and Troubleshooting a Notebook LCD Panel Issue.

If you require further assistance, let me know and I will gladly do all I can to help. If this helped resolve the issue, please mark this post as Accept as Solution.

Thanks!

Thanks blitzgaming. That's what I thought so, and to my laptop to hp service centre but they said it have some issue with its motherboard. As not satisfied with there answer I went to next service centre in city and they told that it's LED display had problem and it needs to be changed. Now as being totally confused I headed to third service centre and yes they come up with problem in my laptops graphic card. So can you suggest me, what should I do.?
