Oh well i understand ,there is any breakage in voltage for mobile laptop screen or any capacitor get loosed. Mostly Capacitor power lose in this type of case

Contact laptop technician because during setting up voltages or changing capictor yourself is dangrous,

Six months ago screen went black and after a week start working..same thing happen last week and yesterday screen was fine after a week of black screen.Just one hour ago it went black again after a day.What is the cause.When black it does not turn on with battery replacement,on ,off.
Only additional monitor gives the picture.
Is it some wire is loose,or need soldering on motherboard??Please advise??

Thanks.
I agree with you.It is hardware problem after performing above diagnostic staeps.I have to get a screw driver to open and check,if i can find laptop screen wires loose.Is screw driver for laptop different than regular screw driver?? How it look like??.Thanks
