TV will not stay powered on
Hello all!
My aunt has a Vizio D48-f-f0 smart tv. One day it randomly stopped working and would not power on. Attempted other power cables and outlets but no luck. So I took the TV home with me and took the back shell off it, and discovered this model tv only has 1 motherboard (that serves both as a power supply and also tv processing) I found the exact part number replacement and bought and installed. The TV will now power up for about 5/6 seconds but then will power back off. I can see the input menu briefly but does not load any smart tv sections and also can not seem to access the menu option. Wanted to see if anyone had any suggestions as to where to go from here...
One thing worth noting, the plug where the power cable connects to the TV wires directly to this board so there is no secondary board
Did a continuity check on cable and also tested volts on the power cable itself, which all tested good
