vizio 32" flat panel tv losing picture??

I bought this Vizio 32" flat panel smart tv second hand.  when i got it home, it worked great for about an hour.  the picture went black.  the sound stayed on.  i called the vizio tech and we changed the back light setting and the ambient light sensor.  this seemed to fix the problem (for about three days) but only until today.  it started it again today.  it goes off every 10-15 minutes and you can leave the tv off for about 5 minutes and it comes back on like nothing is wrong.  the picture and sound are great, and the sound never goes off. has anyone experienced this problem or can anyone tell me how to fix it?
