My Compaq presario CQ42 has a white-red thin line at the right corner of the screen. Is it a problem to use the laptop with it before I fix it.


@tharindupedu

If you see a Vertical/Horizontal colored lines on your LCD, that means either the Video Card, LCD, or the LCD Flex cable (this is the cable that connects your motherboard to your LCD screen) are going bad and needs replacement. You can still use your laptop though but I strongly recommend having it fixed ASAP before it gets worse. You're still under warranty, call HP/Compaq at 1-800-652-6672.


Good luck.
