FAQ:
Q: How do you test a LED strip with a DMM?
A: On a set of LED strips I salvaged, there are actually test points that are just openings in the solder mask. By setting your DMM to diode test mode (or resistance at 2000 range), and touching the test points, the diode will glow if working. Switch the polarities if it doesn’t seem to be working.
Q: How to tell if LED strip is good?
A: LED Strip with Test Points which are just openings in the soldermask. The diagonally opposing dots are fiducials. Test with DMM. It is good. Scratched LED Strip since it has no test points. Test with DMM. It is good.
Q: How to test LED backlight on led (laptop) screen?
A: Now you can test LED backlight on LED (Laptop) screen with MS438EXT. IT02 is our newest Inverter tester; the advantage of this custom built tester is that you can apply any input voltage through DC Jack to the test inverter from the laptop to the LCD TV inverter. It is very simple to use.
Q: How do you remove soldermask from LED strip lights?
A: If you don’t have test points, you can scrape a bit of the soldermask away on one side of the LED. You just need to expose the copper underneath. Since the LED’s are in series, you don’t need two scrapes for every LED, just one between each LED. With a series circuit, one LED going out will take out the whole strip.
