Hey,

bought an LED strip for the balcony, but won't work. It worked originally when we hadn't cut it yet - so the entire strip was lit. There are cutting marks which we used, too. The start of the steip is still lit, up until the cut, the connection seems not to work.

Where's the problem?

Hmm,
Pete

Is there nothing you should do to close up the ends with an endcap or something? Logically it seems you'd have to do something like that to make the system work.
The new Mac Pro has up to 30 MB of cache inside the processor itself. That's more than the HD in my first Mac. Somehow I'm still running out of space.

Huh? We did use the connectors for connecting cut parts of the strip...

perhaps the ground and hot have been switched, which would keep the LED's from lighting.

Depending on the size of the strip itself, it may be difficult to see the "+" and "-" markings at the ends; many strips switch them from one end of a segment to the other. Disconnect the power and check really closely to see that the connections between the end of the working part and the start of the non-working part are "+" to "+" and "-" to "-".

If that's correct, the next thing to check is that the connectors were applied correctly. Polarized or not, it's possible to incorrectly connect the ends to the connectors and wind up with either a reversal or one side not being really connected at all.

Again, do all of this with the power disconnected to avoid damaging anything, including yourself.

Peter,

Can you give us some more information as to what the brand/model is of the LED strip?

I use these LED strips a lot. Can you take a picture of what the connection looks like? If you're using they are quite finicky. Is this the RGB or one color model?

Solved. The cuttings were so inaccurate that the connectors apparently could't work. Gosh, it took ages...
