Television manufacturers produce TVs now with one or two HDMI input on their sets for catching up with the trend of widely HDMI applying. HDMI technology has realized the synchronous transmission of audios and videos with one cable and one interface, which is more advanced than the DVI or VGA technology. However, as most TVs have less than two HDMI input, and if you have more than three HD devices home, you need an HDMI switch to connect all these devices to your TV.
You have got your HDMI switch and used it for a long time. No electric products can ensure they have no problem when using. Thus, if your HDMI switch has a problem of complete signal loss, which no audio or video reaches the television, here gives you a solution. This problem is typically caused by poor-quality or damaged HDMI cables, which sometimes lead to a total signal loss. A non-powered switch can also cause signal-loss problems, as can excessively long HDMI cables.
High-quality HDMI cables and an HDMI switch with an independent power supply can rectify the problem. When doing any type of HDMI switch troubleshooting, the switch should be removed from the set-up to see if the problem continues. If the problem does not continue, then the switch is likely defective and the manufacturer should be contacted about a replacement.
