Now TV boxes have become the chasing artifacts of many families with their high price/performance ratio and rich content.

Now Xiao Bian will teach you a few tricks, and it's easy to get a set-top box without a signal. 
ã€Solution】
1. The most basic method for no signal in the TV box is to check the power supply and plug problem to see if it is loose. If it is a connection problem, you can reconnect directly.
2. If there is a start-up image of the TV box on the TV screen but the message “No signal†is displayed, this phenomenon indicates that the audio/video cable (red, yellow, white) connection between your set-top box and the TV is basically OK, but It may be that the network is not connected successfully. Check the network connection again.
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., there is a possibility that the set-top box is damaged. Both of them are unable to solve the problem and can only be contacted by a qualified professional.
