Timor set-top box no signal solution

1, Timor set-top box no signal The first solution is to check the power supply, plug problems, see if it is loose, etc., if it is re-inserted from it.

2. If the start-up image of the set-top box appears on the TV screen and the “no signal” message is then displayed, this phenomenon proves that the audio/video cable (red, yellow, white) connection between your set-top box and the TV is basically OK, but TV RF input signal lines (note: do not refer to the red, white and yellow) do not receive the set-top box RF input port, or TV RF input signal line is not connected to the terminal box on the wall, or in your room where there are other open circuit.

3, if the TV screen does not appear in the start-up image of the set-top box, and then only the blue screen and there is no text prompts, then there is a problem with your TV's channel settings, please use the TV's remote control press source button or AV / TV button to convert the TV from analog TV channel to video channel.

4. If there is no abnormality in the wiring, etc., it may be that the cable TV network is damaged, or the set-top box is damaged. Both of them are unable to solve the problem and can only be contacted by a qualified professional.

5, find the TV signal source button, switch the TV signal to HDMI or AV signal, switch to the corresponding signal, wait a few seconds, the TV will appear the default image of the Internet TV set-top box. Through the above signal settings, your TV screen still shows no signal, this time not too worried, we now replace the connection line and then test it. Generally, there are AV cables and HDMI cables in the box. If you are using an HDMI HD cable, we will replace it with an AV cable. This can help me determine if there is a problem with the cable. After replacing the line, it still cannot solve the problem. At this time, we need to replace the box after the sale.
