2Frank: Used it to test LED backlight for my 5 year old Samsung TV. Simple to use. Red to the positive and black to the negative. If the strip has no bad lights, then all of them light up slowly to their max voltage. However, the strips I have comes in two forms that need to be connected together when installed in the TV. I find the front strip need to be connected to the back strip for the LED tester to be able to work on the front strip. I can test the back strip without connecting it to the front strip but not vice versa.

Jr.: I have seen quite a few online videos and instructions on how to test LED TV backlights using 9V batteries instead of a “costly tester”. Unfortunately, testing LED TV backlights with 9V batteries is not as economical as it may seem. At 3V per LED, testing a strip of 6 LED would require at least two 9V batteries. Testing an array of twenty LEDs would require about six batteries. Where I'm from a 9V battery is about $3.50 each (x6 batteries) = $21 plus tax. That in addition to wires plus time and effort assembling it.
This LED tester is $19 delivered to my door. It comes complete with test probes and is designed for one specific purpose only – Test LEDs. Whether it’s a single LED, a strip of six or an entire array of twenty plus LEDs, this tester will test them all. I used it to test the top and bottom half backlight arrays of my 55-inch HDTV. Not only I was able to identify the defective strip from the entire array in seconds, but I also zeroed in on the actual bad LED. For individuals with even the most basic electronics background, this tool is simple to use with virtually no risk of damage to the LED since the output is adaptive and automatically adjusts to the...
