Hello there, my parents are having a TV problem.

Since I can't post pictures on here, it's hard to explain, but, when the TV starts up, everything's ok a second, then the screen goes dark on the lower left corner. It's not dead pixels, it's just darker than the other part of the screen? Anyone has the same problem? Or knows if it's repairable. Thanks in advance. via /r/tech https://ift.tt/2DgqZVx
