Ultra HD black screen

Please help!! My VCS has been working fine but today I was making adjustments, and since I have a 4k TV I'd adjust the setting to Ultra HD. Once I did, it reset to a black screen and I'm unable to get any imagine. I wish it would have a reset option if it's not compatible with the TV's 4k settings. I've turned it off, unplugged it, turned it back on and still nothing. I've searched online but find nothing about it. Has anyone else ever had this happen and is there a fix? The only thing I can think of is find someone with a comparable TV to be able to see the settings again to set it back, which will be a horrible pain in the butt because of the entertainment center it's in. Hopefully there's something simple. Any help would be greatly appreciated!
