I have a Samsung QN90A TV and recently I have been having a problem with it, I am getting the black screen. I have no idea why this happens. Could someone please help me to solve the issue?

have you tried samsung technical support, or the store you bought it from?  This is a private club filled with assholes, not a support forum.

Actually some personal reason, I signed up on this forum and then I was having the issue. So I posted the thread here. I did not try to connect to any Samsung technical support forum. 

If there is any solution on this issue, please help me.

 

You are on the wrong forum. You can start here

Google QN90A black screen

I am not teasing you the info is there but you need to work a lot to find it. There could be a hundred cause. Do not open the box if you have no experience with high voltage it could kill you, only try the other tips!

I am answering you because I had to repair a 3d lg TV myself because the service only wanted to do it for almost the full price of the tv. It was a few months to find the info, parts and equipment but I had no choice because you can not buy 3d TV s nowadays. How can we watch the next Avatars?

Thank you everyone for reverting back. But I have resolved the issue with the help of this article. Actually, the problem was happening due to outdated software. After updating the software properly, the problem got solved. Now I have no longer any issues. The TV screen appears to be the same as before.
