Picture comes in and out

My Samsung did this and this helped after it died a few days later

This happened to me its probably too late for you but might help others. 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!

Newer tv's have startup and shutdown circuits so they're difficult to just wing it like the old days. Could be temperature related but the shutdown is protection intended.

TV has gone into "protect mode" to do just that to protect against the damaging failure that has been detected, you will need a servicer to diagnose the failure. Good luck and Merry Christmas!

unplug the tv, wait 5 mins plug it back in, and without using the remote, press the tv on button. see if its ok.
