HP DV4-1200CTO Flicker at bottom of screen.

    Last year, I bought a HP dv4-1200cto, now days, screen flickering at the taskbar positon(about 5mm hight), I updated BIOS, VGA driver, nothing changed. When I tested memory in bios, no any errors. This laptop is out of warranty for two months. After searched on the web, I found lots of guys have the same problem. It obviously has the manufacturer defects. HP should extended warranty for DV4 model.

Yup its hardware issue. Since you are out of warranty, try you luck by changing the inverter and its cable. Hopefully it will fix it.

Try the cheaper one first, your issue may related to LCD as well. Bad LCD cable or inverter may also showing the same symptoms.
