Awesome. And timely. I have an led tv that has a fault. It has a faint picture that shows up if you shine a flashlight on the display, which I think indicates either a bad led backlight or the board for it. I'd like to fix it if possible. I'm tired of throwing away simple devices because nobody thinks it worth fixing things anymore.

@jenniferwhitewolf37842 жыл бұрын
There is no need to crush/break the LEDs, as mechanical stress has more potential for substrate damage than heat. You may need a smaller exit tip to keep the heat concentrated, and perhaps less air speed.
@TheGuitologist2 жыл бұрын
In this case, I wasn't doing it with damage prevention in mind, only speed. It's very fast removing them by breaking them off and then coming back with the iron. You could be right in your assertion generally, but out of all the ones I replaced, no substrate or pad was damaged using this method.

It's better to heat from underneath. You can preheat, then place the LED on top and heat it again. If the pads match well, the LED will automatically slide into place and flatten itself when the solder melts. And it won't blow it anywhere.
@TigredelMar10 ай бұрын
I've tried this method,however instead of a heat gun, i used a hot plate, it does save you money, but the amount of time its not worthy since some of the brand new strip sets are cheap enough, also, if you just replace the band LEDs on each strip, eventualy the other ones will go bad, its always better to replace all of them with brand new strips. Lastly, those LED lenses are a pain to glue back and some strips if they are just a bit crooked you'll end up with white spots on the screen.

I've fixed two TVs, a Panasonic and an ALDI 'Bauhn'. Both had single led failures which stopped all other leds glowing [series circuits?]. I tracked down the failed led and removed both lens and led. Then I snipped a working led from a spare backlight strip, about 1 1/2 inch of strip either side. Then I 'jumper wired' this in place and stuck it down with double sided tape. Unfortunately in the Bauhn a further led burned out shortly after reassembly and I had to replace it also. I salvaged the backlight strips from a 'broken-screen' tv I found dumped nearby.

Sometimes with backlight failure the screen is still operating. If you shine a light onto the screen you can just make out the picture. If you see that picture then you'll feel more confident that it's just a backlight failure.

Start by buying a proper soldering station like Weller ,jbc or if you are on a tight budget start with a universal 80w soldering iron (80w seems allot but your dealing with a cheap iron)proper tweezer and you need to calculate your led that your gonna replace otherwise after 2 months you gonna replace the same led on that row of line for example you have a Samsung backlight system that requires 3v per led you can replace it with another 3v led universal but you need to know how much what you backlight circuit draws If you backlight uses 3v 1w led I would use a 3v 1.5w led instead by trial and error I found that they last longer than if I would install regular 3v 1w led
