I have a Singing Machine karaoke console with a RCA to hdmi converter connecting to my Samsung Smart TV. At 720p the screen jumps from lyrics to blank screen or sometimes doesn't display at all. I also have a Samsung audio bar.

When I first set it up it worked fine for several months, but now no worky. I am stuck....

My 8 year old daughter is dying to use it. I have exhausted all options.... Appreciate any help!
