LED TV backlight & constant current board (TD3H) is a high grade test and maintenance tool with three utility model patents.
This product has a powerful function: 1.Test any LED back-light strip and LED bead, 2. Test constant current board 3. Test voltages of multiple components.
This product uses AC-DC isolation Switching Mode Power Supply and a series of automatic intelligence to control the circuit, LED double table digital display ,safe and convenient.
The tester has adjustable current with loads,Default factory setting：output voltage 330V，output current 50mA
Plug in power，turn the power switch on，the tester is ready after the voltage rise to 330V and keep steady. You can test any size single LED bead, strip at default settings. If you need testing a single LED bead with unkown polarity, set the voltage to around 20V for safety (be safe as well if get the wrong polarity). And also you can turn to 1mA with the red switch if it is hurt your eyes.
Good product, quite possibly the best tester in the market. But there is still one issue it fails to address: Sometimes LED Backlight strips will only fail when working at their normal current loads, which can be as high as 700mA in some tv models. So it is possible that they will seem to be working when tested with 150mA, but fail when exposed to the current level provided by the TV.

I am testing this tool. Thanks for share this video.
If you encounter any problems, please contact me.
Great video and informative, I have the TKDMR Model TD 28, very handy. But I will get this new model as well.
hi can i use this to find short in the motherboard? can i set this to 3 volts 3amps like the tool called short killer?
I think I've been buying LED's from you on eBay. They have been working great and I gave you a great review on my latest video ✌
thank you very much! friend. If you have any technical questions you can contact me. In the future, we will update more videos.
@@tkdmrlong1781 I'm not sure if your drop shipping the LED's or sell from your own inventory. But would you be interested in selling a bulk qty? It doesn't have to be through ebay.
@@jeffescortlx yes I am the only factory. We can accept custom LOGO and adjust any parameters.
Brilliant, it does get better than this. Wonderful explanation of TKDMR.
Friend, if you are interested in machines, you can add my whatsapp
I blew mines on first use. Can you open the device and tell me what are the values of R16 and R17 please? Right next to the voltage button.
What's a typical current for a tv backlight??
5:47 Very few LED TV's power supply boards use the type of power supply connector included. Why not include different connectors so this feature can be used on more than one brand of TVs?
all brand，just led tv
@@tkdmrlong1781 Did you even look at the connector on the power supply board at 5:47 I was talking about? That connector also at 6:06 doesnt work with "all brand" tvs as you said or are you just saying random shit & have no idea what I said. Maybe get someone whos speaks english to handle your youtube account?
Is the KT4H your new model?
KT4H same TD3H
If you have any technical questions, you can contact me. I will do my best to help you solve the problem.
How is 300v not burning LED?
no problem
@@tkdmrlong1781 That wasnt a compliment, he asked you a a question (hence the question mark), if you dont know the answer, here in america we just say we dont know
I am also asking, 300V?
Good video. Crap "voice"
YOUR SOUND IS HORRIBLE.....

@@tkdmrlong1781 GREAT INFO THOUGH... WOULD BE NICE TO REDO WITH BETTER SOUND... RECORD IN A MORE CLOSED IN ROOM... THANKS FOR THE INFO..
@@renitaedmonds72 Thanks for your advice
