Recall For Vizio E-Series TVsAugust 7, 2014
"The stand assembly can fail and cause the television to tip over unexpectedly, posing a risk of impact injury to the consumer," according to the notice. It's based on 51 reports of the TVs tipping over, although none led to injury.
"Consumers using the stand assembly should immediately detach the stand, place the television in a safe location and contact VIZIO for a replacement stand assembly. Consumers with wall-mounted televisions should request the replacement stand assembly in case the stand is needed for future use," the CPSC said.
