How to fix hdmi cable?

     When most people find that the HDMI signal is interrupted and the picture flashes, the first reaction is to change the new cable. In fact, common faults often come from loose and dirty interfaces. The interface is exposed for a long time, which is very easy to accumulate dust and hair, which hinders signal conduction. Prepare a soft brush and anhydrous alcohol, gently brush the interface, and then carefully wipe it with a cotton swab dipped in alcohol to remove impurities. In many cases, the picture can be "resurrected" in an instant.

     If there is a broken circuit inside the cable, don't give up in a hurry. Professional electricians revealed that breakpoints can be found with a mimeter. There are multiple wires inside the Hdmi Cable. Adjust the multimeter to the resistance gear and detect it segment by segment. The sudden change of the resistance is likely to be the breakpoint. After determining the position, peel off the outer skin, use an electric soldering iron with solder to accurately repair the broken part, and then wrap the insulating tape, and a "resurrected" HDMI cable can fight again.

    What's more creative is that the use of heat-shrinkable tubes and nylon bundles can also reinforce the vulnerable parts of the cable. For example, at the plug connection that is often bent, it is heated and fixed with a heat-shrinkable tube, which can prevent damage to the outer skin; use a bundle belt to regulate the direction of the cable to reduce daily pulling and wear.

   Repairing HDMI cables by hands-on not only saves the cost of replacing them, but also explores the exploration of electronic maintenance skills. Although complex faults still need professional maintenance, mastering these basic repair methods can cope with 80% of minor problems. In the future, let's have more DIY spirit, use clever tricks to "extend the life" of electronic products at home, and enjoy uninterrupted high-definition entertainment.
