Samsung UA55f6400 led flashing

[provider10]

Hi

Have this Samsung TV (maybe elsewhere it will be Un55F, I think the UA prefix is for africa)
on connection the red led flashes in sequences of 5.
On disconnection of the lead between the main board and the power supply' the back lights flash and the relay on the power supply is clicking. Any Ideas please

Power supply then click please check RS802 10 Ohm.
Backlight flashing, then please replace IC9101 SLC2013M.

If you disconnect the cable between the power supply board and the main board, also disconnect the LED cable. Is the power relay still clicking when power up the board?
What Voltage testing have you done on the power supply connector that goes to the main board?
Power supply/LED driver board P/N BN44-00625B

Hi

The power supply only trips when the LED connector is plugged in.

What voltages do I have to check
