Waking up TV remotely after a system restart on the PC i want to remote into.

I am on my holidays and log in daily through TV to a remote desktop to monitor CCTV cameras, Nvr and to run home automation. It appears my remote desktop has gone through a system restart and I get the TV not running on remote PC message. The odd time this has happened before there has been someone to double click the TV icon. Unfortunately this time that someone is on holiday with me :-( Is there a way to remotely wake it so I can continue to access it? Any help would be appreciated TIA
