我家中的電視機沒有了轉制式的功能。無論轉到PAL或NTSC或AUTO, 電視祇有黑白影像而沒有色彩,聲音背後有很大的噪音,好像轉錯了制式時一樣。
怎樣才可以重新設定電視機之功能?
我的電視機是21吋Skyworth CTX- 21NXN...保用期剛過,可惜。
請問有冇人可幫助我???

✔ 最佳答案
You TV set tuner part or tuner control problem , you MUST call TV technician to solve it . (Received signal may not be select correctly it depend on the control is selected system is correct .) You can also try to use AV input to observe the picture has normal (if you have a VCR ) If the picture OK the above problem have 95% in this section . But if picture still NG the Digital signal process circuit have 99% problem
參考: I know the theory of TV circuit

Color signal can be seen via the AV input. The problem maybe on digital control. No matter what TV-sys selected, it always the same and no change at all. This problem happened a year ago & the technician can fix it by using the TV remote controller.

你應該用auto，重新搜一次台看情況如何，因你的情況可能是台訊號不對所致！
