HP pavillion dv6's screen turns black while using it.

[bc130201698]

Hey, i unplugged my battery and charger pressed the button but i think this is not the solution of my problem. I did everything except factory reset and i think it'll only waste my money because it's an hardware fault. I'm facing this issue for 3 months. And i took it to the Laptop repair shop after 3 weeks he can't resolve the issue and told me a solution to how to turn the screen on when the screen turned black. and it works.
Temporary Solution:
Whenever my screen turns black i rub my hand on this metal chips(looks like) ? and the screen turns on. but for it i've to keep my laptop open which is totally a shitty plan. So can anybody help me out to solve this porblem.
