I have an old MacBook Air, which, when using Thunderbolt cable, I am able to mirror the screen on my iMac.
However, I cannot do the same for my newer MacBook 12".
Any ideas?

It seems to me that the frequency you have your laptop configured at is not supported by your TV.
When using mirror displays, it usually mirrors your main screen (resolution & frequency). Your main screen would be the one where you have the Dock and Menu bar.
Can I ask why would you want to mirror display on your TV? Is this for watching videos? If so, I would recommend you to do the following:
- Connect your HDMI cable
- Click on detect displays, disable mirroring
- Install VLC player
With VLC you can use your second screen on full screen mode without the need of mirroring.
The HDMI or VGA adapter that can be purchased from Apple allows mirroring to an external monitor, projector or other display that allows video IN. Does your PC allow video in via HDMI? (I'm not aware of any that do, most are video OUT) There is a 3rd party application called Duet that allows your iOS device to be used as an external or second monitor via USB but I think that is the opposite of what you are trying to accomplish based on your question. The screenshot shows Duet for Mac but there is a PC version as well.
From the Apple documentation regarding cable:
Use the Lightning to VGA Adapter with your iPad with Retina display, iPad mini, iPhone 5, and iPod touch (5th generation) with Lightning connector. The Lightning to VGA Adapter supports mirroring of what is displayed on your device screen including apps, presentations, websites, slideshows, and more — to your VGA-equipped TV, display, projector or other compatible display in up to 1080p HD. It also outputs video content - movies, TV shows, captured video- to your big screen in up to 1080p HD. Simply attach your Lightning to VGA Adapter to the Lightning connector on your device and then to your TV or projector via a VGA cable (sold separately).

Best Answer
Ensure that under
System Preferences > Displays > Arrangement(this tab only shows up if your computer detects an external display), the "Mirror Displays" checkbox at the bottom is checked.This checkbox determines whether your secondary display will act as an "extension" or as a mirror of your primary.
