You could use one of these composite video to HDMI converters:

I've never used one so I can offer better advice but, it should work.

Do you see two phono jacks on input panel? One is for a headphone, the other is for breakout cable like this:

Virtually all VCRs only have analog video and audio connectors. Almost no TV today has those connectors by default anymore, as everything has moved to HDMI. As Tivoburkee mentioned some TVs do have a small jack (looks like a headphone connection) that allows connecting a breakout cable with analog connections, but not all do. I believe one of the analog to HDMI converters offers a better option to connect something with analog only connections.

But I do have to ask, why on earth would someone today want to connect a VCR to anything? Unless you have a bunch of home videos on tape that you still want to watch, the image and audio quality of the best VCR pales to the cheapest DVD player (DVD offers roughly double the image quality potential, naturally dependent on the source material) or Blu Ray player. If it is personal tapes you still have, you can get a fairly inexpensive connector that allows you to record those videos onto your computer, then put them on a DVD. Something as simple as this is only $10 on Amazon.
