Antwoord op "Half of the string of LED Christmas lights doesn't light up."Yes, I frequently use 'bad' string segments as sources of spares as most are usually still good. If the individual lamps are not removable then I splice them in by stripping 1cm off each wire, twisting them end to end and soldering, and finally covering the splice with a 2.5cm piece of dual-wall adhesive-lined black heatshrink tubing to seal the connection . The corroded-off LED leads used to be a big problem back when they used steel leadframes. For some years now they've been using brass so that shouldn't be an issue with newer strings. This can be verified by by pulling out an LED (if removable) and seeing if a magnet sticks to the LED wire leads.
Antwoord op "Half of the string of LED Christmas lights doesn't light up."Hello, i just found this thread. I have been doing Christmas displays for decades and LEDs since they came out. Since Christmas is right around the corner I figured I'd chime in. It is true these LED strings aren't as perfect as we'd been led to believe, but many of the issues can be resolved. The problems spoken of on this forum are many because the failure modes are many. Some problems are similar or identical to those with incandescent light strings, and new ones have been added! (of course.) 1). As mentioned by some, the only truly reliable way to fix a string that has a bad section is to take each lamp (LED or incandescent) out of the nonworking part and swap it into a socket of a known working string of the same type. You may have to do this with every last lamp in the bad section! Do so with great caution, as you're working with a live string. Work on a non conductive surface and make sure you are neither touching anything grounded nor any moist surface. If you doubt your abilities or the situation,...
