TV powering off after pcsleep hass command

I have sleep working using the HASS agent in taskbar on my PC, what I wanted was to have my TV power off also when I hit sleep from within Home Assistant.
I created an automation within HA and it works but on waking the PC with a kb press and switching TV on with remote the TV will then power off after a few seconds.
It seems like it thinks the PC is going in to sleep after it is waking?
Any help appreciated.
