Perfect

Feels cheap in your hand with inferior materials. But it does the job well. Accurate readings but not sure if or how long it will last.

I had a renter that left a LED TV with me, so I attempted to repair it. The tester told me that a lot of the backlight LEDs were bad, and that was the problem that was causing the TV picture to come on, and then go off repeatedly. Unfortunately, when I was taking the TV apart I cut what I thought were pieces of tape off that were attached to the LCD screen, but it turned out they were ribbon cables going to the LCD boards that were glued to the frame. I should have just removed the boards from the frame. Anyways, I ended up trashing the TV.

$17 tester + $30 replacement backlights + YouTube tutorial + a bit of patience = several hundred dollars in savings over the cost of buying a new TV!I'll start by saying that I was, early in my career, an electronic technician, so I'm very comfortable working on electronic gear. That said, I believe that anyone with a bit of DIY aptitude could use the tools listed above to inspect and, as needed, replace a bad set of LEDs in a TV. The purpose of the tester is simply to confirm that the original LEDs are bad. You could skip that step and assume that replacement will correct the issue, but if you're like me and tend to apply your skills to help out friends and neighbors, then the $17 spent can become more of an investment in good will.In any case, it worked, and if you need it, buy it!
