Authorities say he asked to watch a DVD on the family's 40-inch television.
"When she turned to get the DVD, somehow the TV fell over and hit him in the head,'' Linden Police Sergeant Matthew Marcino told the Star Ledger.
He was flown by helicopter to University Hospital in Newark, but he suffered severe head trauma and died.
An investigation is ongoing, but officials do not believe any foul play was involved.
"It appears this was just a tragic accident," Marcino told the newspaper.
