I have seen quite a few online videos and instructions on how to test LED TV backlights using 9V batteries instead of a “costly testerâ€. 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 a 55-inch LG HDTV I was repairing. 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 output required of however many LEDs are tested at the same time. In contrast, a series of 9V batteries always provide full power and can easily damage LEDs.Build quality is decent but I’m not sure how long this will last on heavy-duty repair shop use. This tester is best suited for DIY, hobbyist, students or technicians training. Anyone looking for an easy and effective way of troubleshooting any LED issues including TV backlights this would be your tool. It’s actually more economical in the long run than a series of 9V batteries.

Shipped quickly and arrived without any issues. Plugged it in, It energized to 300V and then I used it to test the LED light strips in my 65" TCL TV. I had a strip that showed open, and all but 3 strips of lights had 1-3 of 7 lights out.Saved me a lot of time and guessing. It was also reassuring that I was able to test the newly installed light strips prior to reassembling the TV. I definitely recommend this product for the home hobby/do it yourself type of person.

I was able to diagnose my 60 inch led tv using this tester, it worked good enough for me to find I needed to replace my back light I also used this tester to find out that my outdoor lights are good just need to replace the power supply

I had a tv where the backlights went out. Was it the light strips or the circuit board?This tool helped me determine the power board that feeds the backlight was fine and there were strips that stopped working. Once I had the TV disassembled (not a job if you are not electronics inclined as you are removing the lcd panel and if that breaks, you are done) I was able to use this tool to isolate three light strips that had one or more bulbs that were not working.It’s a bit of a niche diagnostic tool, but when you need it, this is the right price and does the job.
