Sony led 46NX720 Screen Half side dark


Hey guys,

 

I have been reading this forum for a long time. Got one issue with my own tv, so thought of asking experts here.

 

I have a sony NX720. There was an issue previously with the tv and it got dead with red blinking lights. I got it fixed from a mechanic who change dthe led driver board. But since then i saw half of the screen darker than other half. It was not not too much previously but now it has become more darker so i am not sure what may be the cause. It may be due to that led driver board replacement? should i again contact that mechanic if thats the case? I already spent 250 bucks on it and dont want to keep spending more of it if this is a different issue.
