LED Christmas Lights: Half of the string of LED Christmas lights doesn't light up.

Sun, 29 Dec 2024 15:00:44 -0700

A bit of a low-tech, although seasonal, question for you:

I have a bunch of Noma LED Christmas light strings, each with 70 LEDs. With one string, exactly half of the LEDs don't light up when plugged into the AC. The whole string used to work, and it's only about a year or two old.

My understanding is that Christmas light strings like these are often two independent circuits, with fuses built into the plugs at either end. I notice that most of the way through the string there are three wires—but at the middle-point of the string, there are only two wires joining the 2 halves. So, this idea that there are actually two independent circuits seems to make sense to me. There must be a fault in the 2nd half of the string, or the fuse in that half must have blown.

My question is this:

Has anybody ever tried repairing this kind of LED Christmas light string? Is it worth it to try replacing the fuse? (Of course, it would only make sense doing so if there wasn't some other more serious fault in the circuit—but how would you debug the cause of the failure?)

The plug at the end with the problem looks like it has a small catch you could push in with a small screwdriver, but it appears almost impossible to pry open the plug without damaging it. Even if I did get the plug open and find the fuse, I'm wondering if the fuse is even some standard size or type that can be readily replaced. Is this just a one-shot type of fuse?

Failing repairing the 2nd half, I might cut the string in two and just insulate and seal the cut end with heat shrink. Has anybody done this to a broken string of LED lights?

Furby: How can I fix for my furby does not speak?

Sat, 14 Feb 2026 20:35:56 -0700

My Furby doesn't not speak and only does the movement.

I thought that it is because of low battery.

Then I changed with new batteries.

But it still doesn't speak.

Incandescent Light: I can't change the lightbulb by myself!

Fri, 24 Jul 2015 12:11:09 -0700

I have a bulb out in one of my lamps. Can someone come over and change it, please. Please be sure the wattage is consistent with what the lamp can handle. I prefer soft white and am a GE fan, but any manufacturer will do. Also, I don't really like the energy saving flourescent as they cast a ghastly green shadow on my otherwise ghostly complexion.

Bicycle: How do I straighten a bent wheel rim?

Fri, 05 Jun 2020 10:18:30 -0700

One of the rims on my bike is very bent; it stops after 1/2 a revolution because the bent part hits the brake pads.

I've heard that I need a spoke key, and also read that the best way to get a rim straight is to just take it to a pro, since it is somewhat of an art. Is this something I can tackle on my own?

Fan: Fan blades turn slowly on Electric Window Fan-- how to fix?

Wed, 18 Aug 2021 19:58:51 -0700

The W B Marvin Mfg Company (of Urbana, Ohio) made wonderful window fans flanked by screens. The frame could expand sideways, so these fans fit into any window with a width of 22" or more (up to about 37"). Circulated the air, but kept the bugs outside!

I really like these fans, and I have several. One is not working well: the fan-blade assembly turns very slowly -- a single go-round takes about 3 seconds. I'm guessing that the motor needs to be oiled or to have some gunk cleaned out. Or maybe the problem is a bearing gone bad. Or...? Ideas? suggestions? instructions on how to fix this? I'm handy, but I've never done any repairs on small motors.

Too bad that Marvin Mfg went out of business.

Mr. Christmas Musical Carousel: Why is the carousel not turning?

Wed, 24 Dec 2025 22:28:42 -0700

I have a Mr. Christmas Carousel, and it stopped turning. Now it just plays music. I tried to open it up, but the bottom wouldn't come off. I have a soldering iron and any other tool that would need. I took the screws out of the bottom and I tried prying it off, but that didn't do anything. If I can get the bottom off, I can fix the problem. I am guessing that it is a disconnected wire. Any ideas on getting the bottom off or an alternate method is greatly appreciated.

I bought some ceramic knives when I had my steel one sharpened. Loved them—for say 6 months. Then—well, steel knives I sharpen with the steel, and then have them ground. With ceramics—sharpening professionally is $$$$.
