play a movie on my Blue Ray.? I have checked the cords and inputs. It worked last night and no cords or inputs were switched. I think my 2 year old got a hold of the remote. How do I fix this?
I only have an HDMI cord, no red, white, and yellow cord.
After trying everything imaginable the solution was simple. I turned the power off to the tv for 5 minutes and after that everything worked fine.

Depends on how your running your tv if its though hdmi you should have it all but judging by you saying cords i take it your using components or the good old red white yellow wires. If so go to settings and in the picture settings make sure its not set to hdmi or make sure it reading digital video. Should fix your problem keep the remotes high up away from the kids
