Synology RT2600ac Not Powering On

[shrieram]

I think I've blown the fuse inside the router. The router was functioning well & couple of weeks back there was smoke smell coming out of the router & I switched it off and let it cool. Few hours later I switched on & the router isn't turning on anymore. Any ideas on how to get this fixed ? Not sure if the fuse is blown or power circuit is malfunctioning. Please help.

that might mean a blow capacitor in the power supply. A fuse would only protect for an over current.
blown caps have an oily smell in many cases. If it is a discrete component, sometimes a good electronics repair shop can replace a blown cap. If it is surface mount or an IC, then board replacement is likely.
you should talk with synology customer support, particularly if still under warranty.
