I have pavilion g6 laptop it's screen is flickering I don't know why in the starting the flickering occur only when I start the device but now it's permanently there. So I can not use my laptop how to solve this issue???
This could be due to either or both of two problems:
1) Screen dying
2) Video chipset failing
To check out 1), connect an external monitor to a video output jack and reboot the laptop.
IF the flickering is present on both the laptop screen and the external monitor, it means your video chipset is failing and since those are not customer replaceable parts, you would have to get the laptop serviced to repair that.
If the flickering is only present on the laptop screen but not on the external monitor, that means your screen is failing and needs to be replaced.
