LED tester

Hello friends greetings to all colleagues ..... I have a doubt friends I need to know if with the led strip tester that is in a video here that uses a bridge rectifier a resistor 330 an electrilitic 250v etc ... it serves me to test from the connector all the LEDs without disassembling the entire screen since they are delicate that is my doubt it works to test from the connector aver if it illuminates the entire screen? ... Thanks and Regards

Yes, it is useful to test one, the strip or all the complete strips. The red LED on the circuit must be canceled and the 10k resistor must be 4 watts.

ok but friend why should i cancel the diode and the r? I mean why can't I use it like this? regards

I did not say to cancel the resistance, no, it must be 4 watts. In the other circuit a red led diode appears in series with the 10 k resistor, for better performance of the tester you must cancel the red led diode, as it is in The circuit that happens to him.

ok friend one thing the rectifier bridge can I do it with 4 diodes? And the resistance of 10k that I have nose if it is 4wat is small and is the only one I have will serve the same colleague?

and the capacitor that I have is 400v 47uf anyway it works?

If you can make the bridge with common diodes. The resistance. Take tempwratura for the consumption of the LEDs. If you do not have a 4-watt one, use a smaller one but for less time

You must insulate everything and not touch the probes. Watch out for the discharges.

But if I can play some tips like the video? otherwise you didn't answer me is the 400v 100uf filter useful? and the 330k resistance is very small too ... does the same serve friend?

Do not put such large capacitors, they take a long time to download. 10 or 22 microfarads x 400v, there is plenty ... the 330 k r girl serves you.

ready friend ... you did not answer me if the tips one happens something? if by chance they join and trouble ....? well thanks colleague .... greetings

Thanks to the 10 k resistor they can be joined and nothing happens, so that resistance has to be 4 watts.

friend victor the tester does not work for me .... or do I have to bridge the connector where the LEDs go?

It has voltage on the tips, if it has voltage it works. The red must go on the + of the card and the black on the negative of the card of the LEDs. If it does not turn on it is because it has burned or open LEDs.

You can assemble the other Picerno tester which is basically a capacitive source: (220v AC) C1 is polyester, preferably 400v or 630v

I use the one that happens to him and I have no problems with any led tv, what happens is that if I arm it badly it will not work, besides it is too simple to not work and has the advantage that you can try a led, a LED strip or all together.

Friend if Victor E tells you IT IS TOWARDS I would try it with a LED New not of the strips And if it doesn't work it is because you made a mistake in making something Good Luck THE PELA
