Hello,

This happened to me. what i did to fix this is, I put the tv onto a radio channel (with no picture) and about 10 mins later i turned the volume down and realised the screen was still on as the volume bar showed up. so i guessed it the problem was to do with light so i went on the menu and went into features and turned the backlight onto minimum and the tv has been fine since. hope this helps!
