Sounds like it's a resolution issue - the TV is unable to display the resolution.

You could try going into safe mode when it boots, delete the graphics card from device manager and restart, but i'm not sure if that would resolve it.

Just found another possible option.. once you think the PC has booted up, could try pressing: Win + ctrl + shift + B Gpu reset command.

Done a quick google and lots of suggestions, might be worth looking at: https://smallbusiness.chron.com/change-monitors-resolution-high-display-68388.html
