Have a vizio 55" had the power board and main board replaced

Customer Question

have a vizio 55" had the power board and main board replaced already. The problem im having is this. It all turns on and then after about 5-10 min it starts flashing the screen like its flickering and then its gone but the vizio name still is white as its on. then if i let it cool the screen comes back on. I have 2 main boards and one i know is shot as it won't come on at all and 2 power boards and both are fine. What could it technically be. Maybe a buffer or what ever its called board instead? Is it another main board issue im just at a loss.
