The power dissipation capacity of SMT is set by its physical size (for the same resistor material). I guess from the photo those might perhaps be around 200 mW each, but having the 2 in parallel means they share the current and dissipation equally. Without knowing their specific function, even if they pass more than 250 mA as a startup surge limiter/fusible link, the resulting dissipation will be much less than 400 mW.
The combined resistance will also be halved to 0.75 Ohm. So whilst 2 identical SMT resistors could be fitted, a single larger resistor of the lower value could be used. This is not a standard value from the E12 resistance scale, but it's possible either standard value 0.68 or 0.82 would do. But simplest would probably be to solder 2 small (eg 1/4 W) standard resistors across the existing SMT ones.
Have you been able to confirm with a meter that the existing ones have gone open circuit? If so there would be no real need to remove them if you can fit standard resistors. On the other hand, if they have got very hot but not failed, that would indicate something else has died first, such as one of the ICs or other devices. Either way, you might still find replacing the resistors could reveal more damage. Hopefully the resistors will have sacrificed themselves and preserved the rest.
