When you supply the 18 volts, do you need to limit it's current with a power supply setting or does the internal resistance in the LED's limit the current to a safe level?
Thank you very much for sharing this information. What is the supply DC voltage for the led stripes? Is 19 volt as you measured it? Thank you again for your time and effort?
best regards and special thanks for your valuable comment voltage value depends on the LED type, the voltage are maintained by the monitoring the current by the LED driver
From my RepairCafé experience I can say, the LED backlight strip is the most common failure on Flat-TVs nowadays. It will last shorter and shorter, often not more than 3-4 years. Often these TVs will be thrown away in my country. What a waste of resources. Thank you for your repair video.
yes sir you are right. the main reason is that the LEDs used in LED strips are poor quality, which have very low operational hours life. this technique is mainly used to reduce the life and increase the sale best regards and special thanks sir
Sir mery pass 32inch led i thi uski backlight kharB thi.. Aik strip se 2 led jali hui thi main ne sme voltage ki led se replace kia.. Jo kharab thi wo 6 volt ki thi main ne Led bulb se 6 volt ki led lagai to laght theak se chal rahi thi.. Led bnd kr k on ki to chalny lagi lekin kuch dair bad phir screen black hogai . Sir 2bara kesy led jal gai
After replacing the LEDs. Some Emmitts yellowish light and reflects on the screen. What could be the problem sir. I fail to it out. I tried using white spray, but no difference.
Gentleman you used flux for soldering LED but did not bother to clean it with IPA. Flux is acidic in nature, so copper on track will be eaten away by flux in few months, again problem will reoccur. This is from my past experience, I'm active in this field from last 45 years.
What causes Backlight to get spoiled .. I replaced a single Backlight, 2 months later the same backlight which was replaced is already burnt and spoiled... All other Backlight are working
Not to mention in some places shipping is expensive, and they are better off swapping g out parts from old tvs. You'd be surprised at how creative they are! We get lazy in the US and such. With things so easily available.
Always great to watch your work. Thank you

When you supply the 18 volts, do you need to limit it's current with a power supply setting or does the internal resistance in the LED's limit the current to a safe level?
each led consumes 3 volts, so its the right amount of power for a 6 led stripe,

Do you need LCD TV backlight belt?Our manufacturer can provide you with a large number of products.
What causes Backlight to get spoiled .. I replaced a single Backlight, 2 months later the same backlight which was replaced is already burnt and spoiled... All other Backlight are working

It is not worth to rework 3 out of 6 Leds.
you are right, i just demonstrated how to overcome some issue when we don't have the spare one

@GrumpyOldFucker another 3 will be dead soon. Who will pay to open entire layers of TV? This is call thukpatti kam.
Nice sharing
