Time to ban high capacity (inch) TVs.....for the children.
My grandson did this. They were staying with us and had a tv on top of a chest. He was changing the channel. Fortunately when it fell the chest went with it at an angle and missed him. It really scared us though.
Remember the old floormodel TVs? Wish I could find one......much safer.
There's no excuse for this. You don't put a 36-64" wide TV on top of an Ikea type 15" Stand.....and don't even think about casters.
I remember years ago, a nurse was killed when, after opening the bottom drawer of 48" wide file cabinet and leaving it extended,.....she opened the next to the bottom drawer and left it partly out. When she was opening the third drawer, the center of gravity changed and the entire file unit fell over on her, crushed her chest I think. All those cabinets should have been screwed to a blocked wall.
Secure your stuff folks.
