    thank you for this video , I got white spot on thr screen after replacing LED'S lenses , I think it was because of the wrong glue I used it called (Permatex super glue gel) ,
    I thought it is good adhesive to use as it's heat resistant, but unfortunately it will damage the lenses while drying on them making them foggy, I wonder if your UV light heat resident and doesn't make a fog after drying

    I had the same problem,, except after changing the back lights and testing, no power to the lights from the board. Bought a used board, same thing. All lights worked with tester. No voltage from power board. Too bad there isn't a simple test plug(s) rather than checking voltages with probes.

    Author: ????? ?????? says "Rapid cooling process is not recommended for the LEDs from the peak temperature… Hand soldering at the lowest possible temperature is desirable for the LEDs… The power dissipation of the soldering iron should be lower than 15W and the surface temperature of the device should be controlled at or under 230?… Use Teflon-type tweezers to grab the base of the LED and do not apply mechanical pressure on the surface of the encapsulant… etc."

    Excellent work, a question: what adhesive do you use? Do the lenses have a specific position? What is the blue device that you use and for what? What type of leds are … What are the characteristics?

    Dont try this watcher, the maker of this video do things wrong, he didn't unlocked the led/screen driverboard, het made too much mistake, and het could have cracked the screen easy. I dont recommened this to anyone to this way.You have to use suctioncups, first unplug all screen printboards and finally the screen. Look at his scary solder iron. I have a bad feelin about his professionalty.

    Nice video! I have an LG 32LB552A model. Does it also use the same 3535 6v LEDs? How do I find that out? Same problem with the one you are repairing and the TVs look identical even though the model numbers are different. I just need the specific LED bulb model number to be able to replace it. Thank you in advance!

    Probably you are a very poor master? You have no money for normal equipment for repairing the backlight.
