There are different manifestation of a YSUS failure depending on how it failed (shorted out, opened completely or partially failed - neither shorted nor blown open) and almost all of them can also be caused by other failures too.

Dark screen, flashing screen, TV refusing to power on are probably the most common ones.

The best way to know your 6871QYH051P has failed is to find a blown fuse on it - usually FS152 located on top of the power connector P151.
You can't visually see if the fuse is open, at least the original fuses used on the boards are ceramic and the wire inside can not be seen, so you will need to use an ohm-metter or other continuity tester.
If the TV doesn't want to come up when the board is connected, but comes on and stays on (even with dark screen) when the board is disconnected from power then this is another reliable indication it has a problem and needs to be serviced or replaced.
