Hi Sense LEDN50K20DGP Dim picture Repaired

[Grunder]

Hi guys,

Another dim display solved by repairing the lamp house.
photo 1 shows dim illumination with the last led on strip 8 not burning.

Photo 2 shows that i swapped strip 8 with strip 12, putting the faulty led in the bottom right hand corner. lamps still burning dimly.

Photo 3 shows the faulty led have been replaced with a 1n4148 (i dont know if this is "legal")

Photo 4 shows leds now all burning brightly.


The faulty led read about 1.5 megohm either way.
A good led showed no resistance either way on my dmm's resistor setting, but illuminated when i foward biased the led on my dmm's diode setting.

Thanks to the guys who posted the information on led & flourescent illumination.

You should use 5 1n4007 in series to simulate one white LED, 1N4148 is not going to last.

Thanks Budm, I didn't know the Led's handled so many amps, in future will use the stacking method as demonstrated in ReeceyBurgers video.
