Flat Screen Tv With Sound, No Picture Repaired?

My Telly is a 55″ Smart LED/LCD HDTV. Made by Vizio. The Tv motion picture has gone out but audio even so works. Screen is NOT croaky. The screen is blackness. TV powers on. The LED light comes on briefly. Screen sometimes flickers. The screen flickers in a dark room for a dissever moment. Turning the TV from ON to OFF causes it to flicker white and greyness. This is before the audio will come up on. I removed the dorsum console cover and checked the boards. I am not certain what to look for to see if a lath or a part on a board is damaged. The audio works. Is there a manner to check and meet if one of the boards is causing this consequence? If I do find the problem, is there somewhere to purchase a new lath for my Idiot box at a decent toll?
