My Dell inspiron 15R display goes black after using for some time?
I'd bought a Dell's AMD version of inspiron 15r laptop about 3 years ago.
I have been experiencing a very annoying and frustrating problem since last few months.
While I was doing some work on it,
the screen went black all of a sudden.
It happened once few hours prior to then, and force rebooting had solved the problem at that time, so I calmed myself and did a force reboot.
But it didn't solve the problem this time.
I tried rebooting 3,4 times, but still no solution.
The screen was black even in the entire process of booting from the beginning.
I also found out that the screen wasn't totally black.
The screen had shown very mere display which was like 0.001% away from perfect dark black.I did as much research as I can for solution, but I couldn't get any good answer..
I couldn't solve it for several hours.
Several hours passed , and I tried booting it up again.
For few minutes, it seemed to be the same old black (or dark) screen.
But it automatically turned back to normal brightness again.
I haven't done anything to it.
Every now and then after working just fine for an hour or so, the screen goes black. The sound and all is clearly audible if a video or audio is playing but there is no display on the screen.
I'm wondering why this is happening..
Can anyone give me an answer to this?
Is it a problem of loosened cable connection to the screen or it is with motherboard or LCD Screen itself ???
