At times, your TV may struggle to detect channels or experience channel loss, a common issue that can be frustrating. To understand the reasons and address this problem, let's delve into the following article!
1. Check the TV's power source
Modern TVs on the market come with various smart features. You can not only watch television with available channels but also connect to numerous other devices such as USBs, computers, laptops, tablets, video players, etc., enabling you to fulfill your diverse entertainment needs.
Diverse connections can also be troublesome, as selecting the wrong input source as the TV channel won't scan or may lose channels.
To remedy this, you need to press the SOURCE, INPUT button or a button with arrows and circles, arrows and squares, etc. (depending on your TV brand), then select a suitable input source.
Press the SOURCE, INPUT button to select the appropriate input source
To scan all channels, you should scan each corresponding channel mode with each respective icon.
For example: You should simultaneously scan for Analog channels and Digital channels, scan using ATV and also DVB-T2, DVB-C,.. or scan via cable if your household is using cable TV.
Select each channel mode to ensure you have all desired channels scanned
2. Does your TV support DVB-T2?
Currently, the government is implementing DVB-T2 coverage replacing conventional channels with digital channels.
If your household falls within an area with interrupted channels, TV without DVB-T2 support or you do not subscribe to paid TV services (cable TV, internet TV, digital TV, etc.), you won't be able to scan channels on your TV anymore.
To address this issue, you must purchase a new TV with DVB-T2 support or buy an additional digital set-top box.
Choose a TV with DVB-T2 to access more channels
3. Antenna placement and quality
TV failing to scan channels or losing channels partially can also be due to antenna placement and quality issues.
If your household is in a remote area, with poor coverage, far from broadcasting stations, the signal for various channels will be very weak. Additionally, using an old antenna for many years or improper alignment can result in fewer channels or lower quality signals.
You need to replace the old antenna if it's too worn out or select the appropriate direction for rotating frequency, adjusting the antenna's direction to scan for more channels.
Replace the old antenna and find the suitable rotating frequency direction to scan for more channels
4. Try manual channel scanning
TVs are always equipped with 2 channel scanning modes: Automatic scanning and manual scanning (manual mode).
Most of the time, you will choose to use the automatic scanning mode; the limitation of this mode is that if the signal is weak, it will not scan many channels.
If your TV is missing too many channels, you should try scanning channels manually to find more channels.

5. Restore TV settings and rescan channels
Resetting to factory settings (TV reset) is a simple and quick way to address TV channel scanning issues.
If you have tried various methods to fix the issue without success, try resetting the TV and double-check the antenna, input source selection, manual channel scanning,.. once again.
If you have tried all methods but the TV still cannot scan channels, contact the manufacturer's warranty center or reputable stores for assistance.
