This will clear and reset the video settings..
Maybe also confirm it doesn't work on another tv, with other cables etc..
If all of that doesn't help, and you can't get to recovery menu, then your hdd may have taken a dump.. I suppose at that point you could replace your hdd with a known working 2.5" sata hdd.
Let us know how it goes.
