HOW TO Quickly Test a LED (including SMD LEDs) #testing #electronics #DIY

What do you think the dark spot is on the first one? Also, does the whole strip not turn on based on these individual LEDs not working?

Great video. I use it to test my backlight. Can you give me an expect answer for few short questions?
1.Few LED on my string are broken, one have dot, but t he other look great and have 860 Ohms resistance when measured in the wrong way (just like the working leds). What's the deal with that?
2. The LED with a dot have no resistance in the wrong way, 100% burn. Could I bridge the path with a resistor or a wire for temp solution until replacement unit arrive?
Thanks, happy new year :)

OMG that music is sooo annoying.. cant concentrate

so tired of chinese leds

I would assume the light has to be plugged in to test?

Vid on new types would be cool

Having the same problem with higher wattage bulb not lighting the led with multimeter. Thank you for confirming need more voltage

can i do this on bare component without any soldering?

But with tester you can check only 3V Leds?
