確認是數碼天線模式
部分電視會同時提供模擬、數碼、有線或衛星模式。請確認你正在使用正確的地面數碼模式。

重新搜台Channel Scan
搜台問題
重新搜台後仍然
找不到頻道
很多時不是訊號完全沒有，而是電視設定在錯誤模式、只做了快速搜台，或訊號本身太弱，導致掃描不到完整頻道表。
Scan Issues
No Channels After
Rescanning
Often the signal is not completely absent. The TV may be in the wrong mode, only a partial scan was used, or the signal is too weak for a stable scan result.
先排除設定問題
使用完整自動搜台
快速搜台可能略過部分頻道組合。若掃描結果不完整，應改用完整自動搜台。
重置舊頻道表
某些機型在多次搜台後會殘留舊設定。清除頻道清單後再重新搜台，通常更穩定。
更新或重開電視
特別是較舊型號，重開或重置設定後再掃描，有時能避開暫時性軟件錯誤。
Rule Out Setup Errors First
Use The Correct TV Mode
Some TVs offer analogue, digital terrestrial, cable, and satellite modes. Make sure the scan is running in the correct terrestrial mode.
Use A Full Auto Scan
A quick scan may skip part of the lineup. A full automatic scan is safer when results look incomplete.
Clear The Old Channel List
Some models behave better after the previous channel table is cleared before rescanning.
Restart Or Reset The TV
On older models, a restart or settings reset can remove temporary software issues before scanning again.
如果仍然掃不到
大廈結果偏弱
如果大廈本身屬邊緣接收，先檢查天線與線路，不要只重複搜台。
接頭或分線器鬆脫
掃描時對訊號穩定度要求較高。鬆脫接頭或損耗過高的分線器常會令搜台失敗。
只有一部電視掃不到
可先換另一條線或另一個插座。若其他電視正常，問題通常較接近單位內路徑或設備本身。
If Scanning Still Fails
The Building Result Is Weak
If the building itself is marginal, do not keep rescanning without checking the antenna and cable path.
Loose Connectors Or Splitter Loss
Scanning needs stable signal. A loose connector or excessive loss in the path can easily break the scan.
Only One TV Cannot Scan
Swap cables or outlets first. If other TVs work, the issue is more likely local to that room or that device.
下一步
想先查大廈結果，再決定是否需要天線檢查？
先搜尋地址，再把「搜台後仍無頻道」情況一併發給 Techiteasy，可更快判斷是否是設定或訊號路徑問題。
