You have just bought a brand-new television, plugged it in, run a channel scan, and discovered it picks up fewer channels than your old TV. It is a frustrating experience that catches many people off guard.
The good news is that there is usually a logical explanation, and in most cases, the problem can be fixed.

Tuner Sensitivity Varies Between TVs
Every TV has a built-in digital tuner that receives and decodes broadcast signals. Not all tuners are created equal. Premium TVs tend to have more sensitive tuners that can lock onto weaker signals, while some budget models have tuners that struggle with anything less than a strong, clean signal.
If your old TV had a particularly good tuner, your new one may not perform as well on the same antenna system, especially if your signal strength is marginal.
Your Old TV May Have Been Retuned Over Time
If you had your old TV for several years, it may have been retuned multiple times to account for changes in broadcast frequencies. Your new TV starts from scratch with a fresh channel scan.
If broadcast conditions have changed since you last set up a TV, or if your antenna has shifted or deteriorated in the meantime, the new TV is effectively revealing the current state of your signal.
Check Your Connections
When setting up a new TV, it is easy to accidentally introduce issues:
- →Make sure the coaxial cable is firmly connected to the antenna input on the back of the TV
- →Use the same wall outlet and cable that was connected to your old TV
- →A loose or corroded connector can cause significant signal loss
Good to Know
Make sure you perform a complete auto-tune or channel scan on your new TV, not a quick scan. A full scan checks all available frequencies and takes several minutes to complete.
Your Antenna May Need Attention
If your new TV is still getting fewer channels after checking all connections and running a full scan, the issue may be with your antenna system rather than the TV. An ageing antenna, degraded cabling, or a shifted alignment could all be contributing.
