Screen Goes Black some times

Here it goes, first of all… Hello guys!

Here’s the deal…

Yesterday I was using the MacBook Pro normally, everything was working just fine. Then, the screen went black, but keyboard lights still on.

So I run to the TV and connected it via HDMI cable and that was working fine! Tried to reboot several times, but all I got that was working was via HDMI to the TV.

Then, today I opened up my MacBook Pro and disconnect/reconnected the LVDS cable, the screen came back again just fine…

A problem I should worry about???
