nest failure after power outage

power outage yesterday, now nest thermostat not controlling boiler.Nest and Nest app talk to each other but thermostat not talking to heatlink as boiler now on continuously and not responding to thermostat temperature settings.Have tried 10 second reset and removed schedule plus restarted stat via thermostat settings menu, all no avail.Worked ok for a few hours then suddenly switchs on and refuses to talk to thermostat.Thermostat is hard wired to heatlink.

Can anyone help.I think a power surge may have blown circuit board?
