Hi tobiastv you have reason kapo prove voltage in + of led and mass as you said, without giving power it has 11.9 v when pulse power goes up to 27v which is when it turns on and off it goes down the voltage to 11.9v. 3 strips. I did not understand the polarity reversed well. I do not have the LEDs on hand I will have to travel to the city one of these days of the week possibly on Wednesday the LEDs have to be 6 v?
Hello, I change all the LEDs and modify the source, if you want you can put new strips, modify the source and forget
I show you a case of source modification so we advance, any doubt here I am

I will have the good vibes of adding that you are before the finest display that manipulates, thinks and is very delicate, breaks from nothing
luck
Thanks tobiastv a good contribution it is always good to find people as a voice that give you their connoisseurs I buy the LEDs if I get them in the electronic stores because they were on vacation and if it is the very finite display and I will be careful, I tell you when
perform
sorry I tell you when I make the changes of LEDs a big abrasive and again thank you infinite thanks
Hello tobiastv sorry for the delay, I tell you that two of the 6 led bars were burned 3 LEDs in each bar, a single bar lit all the LEDs, what I did is with a colleague is to change the three LEDs of each bar, I cost less than a new bar that cost me 650 pesos each bar, I put them on, 2 hours ago it's walking with image and sound, I also canceled the resistances at the source. I wouldn't have fixed it without your help, thanks to voice and everyone from the forum community, a hug and a handshake at a distance.
