Default Vestel 17PW25-4 repair - resistor value?

I bought a repair kit for this TV power supply. Shorted diodes, FET and several tiny surface mount components to replace. On starting the repair I noticed someone had had a try before me and even helpfully ripped up some of the PCB pads. In spite of that I think I've managed to get everything in place and connected up correctly.

My question. The schematic for this power supply (attached) lists SMD resistor R923 (off pin 4 of FAN7529) as 15R, but the repair kit supplied 100R and the one I removed from the board was also 100R (bearing in mind someone had repaired it before - maybe with same kit?). I wrote to the kit supplier to ask about it and he hasn't replied.

As I don't have the electronics knowledge to know what that resistor value should be, do you think there's any reason a 100R might be supplied instead? If I go ahead and use 100R might there be any consequences?

Thanks!
