2009 Vizio keeps shutting off

[Airedale]

So this was my mom's tv, it keeps randomly shutting off every 10 to 20 minutes. Obviously I don't have a clue as to what may be wrong. So I gave her a 10 year old Samsung tv that was twice the size and told her that this Vizio is dead.

Any idea what may be wrong with this old Vizio? If it's not a simple issue then I'm bringing it to the E-waste scrapper.
