My television has a black screen with a picture of a red key in the lower left corner. I am wondering if somehow we locked the TV and if so, how do we unlock it. It still has sound.
Try pressing the "F" or function button and hold while pressing the Mute or "M" button at the same time. Good Luck

PLEASE,PLEASE DO TRY A SUGGESTION POSTED BY TECHMAN! TRUST ME IT REALLY WORKS! I STUMMBLED ON THIS SITE AND BROWSED THROUGH POSTINGS.I JUST TRIED TECHMAN SOLUTION/SUGGESTION AND 2 MY SURPRISE IT ACTUALLY WORKED INSTANTLY AND IMMEDIATELY.I'VE BEEN UNABLE 2 WATCH MY TV 4 OVER A MONTH NOW, BECAUSE MY LITTLE PRECIOUS 10 MONTH OLD BABY IS CONSTANTLY PLAYING W/ THE REMOTE AND GETTING IT WET INSIDE, SOMEHOW. I THOUGHT I WAS GOING 2 HAVE 2 GO AHEAD AND JUST PURCHASE ANEW TV. SO THANK YOU!THANK YOU!THANK YOU VERY MUCH WHO EVER YOU ARE,TECHMAN!

SOURCE: How can I unlock the TV?
Ok try this.
If you have the display button on your remote then hold that down for 10 seconds it will unlock the screen. If password it requested try 3308 or 6688 and then go into the menu and change the parental controls on the tv as that is what has turned on. Let me know if that helps. If you do not have the display button try holding the mute and the menu button at the same time. Hope that helps.
