Demo video – Computer DIY: Replacing faulty display flex ribbon cable on HP Pavilion DV 6 laptop
When you have a problem with your laptop's display, the problem could be with the LCD display panel or with the flex cable that connects the LCD display to the motherboard. If the display is flickering randomly, it could be the cable issue or loose connection. You may disassemble and try re-seating the cable on the contacts on the motherboard and the LCD display. Also you might need to inspect the LCD Flex ribbon cable and see if there are any wear and tear.
