    New T.V.!!! $60 60inch Vizio Smart T.V. Burnt LEDs, Easy Fix!!!

    Sup Bros!(PewDiePie voice) Just picked up a 60 inch Toshiba E60-C3. I has bright spots, so I could tell that it had Bad LEDs. The pictures on Craigslist and the previous owners description made it sound like a bad LED driver.

    I opened up the TV and Tested the LEDs by trying to use what looked like test points near the LEDs... But those were connected to nothing!!!

    So after scratching the solder mask between each LED I found out that only 10 of the LEDs were burned, out of 12 strips, with 8 LEDs each=96 LEDs!!!

    Fortunately I will only need 10 LEDs.

    I looked online for strips. I thought I saw that shop jimmy and ebay had them for $65 for a whole set. Unfortunately I must have skimmed over it too quickly. The only place that has a set of 12 wants $120!!! And everyone on ebay wants about $20 a strip!!!

    I found a guy on ebay that sells a set of 20 bare LEDs for $15. So I ordered that and I should have this 60 inch beast fixed around the Dec 1st!

    My dad has a 55" vizio smart tv and wants a 65"-75". I told him that he'd get a little bit bigger tv, and when he's ready to get the one he wants he can sell it and help fund the new one!

    The only other concern I have is that I popped a few lenses off some of the LEDs and they all look like the silicone(?) on top/inside of each LED looks dried and cracked. If I had to replace every LED I'd need 5 sets of 20 from that seller. Unless I can find them on Digikey(I looked a little, didn't find quite what I think they would be rated. I could be wrong). Which would cost $75.

    What do you guys think? Should I just replace the burned ones and not worry about the others unless/until they burn out?

    Well, you bounce from Vizio to Hitachi, so we have no idea what your TV is. Replacing individual LEDs is fairly simple, provided you have the proper tools. Your best bet in finding nearly exact replacement LEDs is on AliExpress, although ebay will sometimes have what you need (they just bought theirs from AliExpress and are reselling them - for a huge profit). You can usually pick up 100 LEDs for less than $10 including shipping from Ali, so the risks aren't very high. It takes about 3 weeks for shipping.

    Just replace the burned out LEDs and don't worry about the rest. Once your TV is working, turn down the brightness. I find that the difference in brightness from 100 to 60 is virtually undetectable. This alone will greatly extend the life of the LEDs.

        I just replace the damaged ones. Simple job with a hot plate and identical LEDs
        Whilst there are plenty of "compatible" LEDs on Ali it's the colour you need to watch.
        I recently fitted a single replacement in a Panasonic smart TV. It's ever so slightly warmer, and if you know where to look on a white background the colour is slightly yellow rather than white. I paid about £3 for 100 rather than £80 for a replacement edge strip.

          I'm guessing for even preheating of the work piece?

          Never heard of that before but now I'm curious.

                  It's a Honton 2020, a bit oversized so I'm making a small one.
                  Not for preheating, I place the LED strip on top of it, the solder melts and I drop on the replacement LED.

                    Make sure to verify the footprint of the LED first.
                    Most LG has large pad for the ANODE which is soldered to the large copper pad of the strip to dissipate the heat.
                    The second link (LG LED) in post 8 is what I use for LG panel.

                      I do mine with hot air. I do them while still on panel. Just make sure nothing underneath to melt. To replace I heat up pads till molten then drop led on and heat for couple seconds. I replace lens with led lit. Makes it easy to center lens. Which is very important or you will get half moons of light. I also run them for awhile before replacing panel. If they flicker after they heat up you need to resolder them
                      I assume no responsibility for any stupid suggestions I might post.

                        I use this hot plate as a preheater:

                        https://www.badcaps.net/forum/attach...1&d=1511820629

                        I bring the item to about 250 F, then use an SMD air gun to take the temp up to reflow. If you use the hot plate to reflow, you run the risk of over-heating the board - its temperature isn't well controlled.

                            A lot of VIZIOs use heat conductive double sided tape to attach the LED strips to the chassis. If you try to repair these strips in situ, you run the risk of ruining this strip of tape. If you do, it will no longer conduct heat efficiently and it will possibly lead to further failures down the road.

                            I use a hair dryer to remove the strips from the tape (leaving the tape in place) and repair the bad LEDs at my bench.

It will be the one on the left side-the one they use is puny! I stuck a much better aluminum one in there ans used good heatsink paste. I don't think they used ANY!

                                    I was given this TV from my great uncle. He said it just wouldn't turn on one day out of nowhere, replaced the TV, and gave it to me to possibly fix and use for myself.

                                    Upon bringing it home and plugging it up, it showed a standby light.

                                    I powered it on and without a flashlight, the display showed the "V" but the lighting is very dim, but visible.

                                    The screen seems to blackout and stay black, but with a flashlight I can see the display.

                                    With my Playstation 4 connected via HDMI, and running a game I can hear sound.

                                    Assuming...

                                    Corsair K70 LUX RGB dying LEDs

                                    Hi there !

                                    I'm having an issue for several weeks with my quite old K70 LUX RGB keyboard. I haven't used it for few months, and once I setup up again my desktop computer, I got several dead LEDs on that keyboard. I tried the Corsair troubleshooting thing (disabling options in iCUE, ...) but nothing changed so I conclude that for some reason some LEDs went in retirement...😅
                                    Decision taken to change these LEDs as I have access to desoldering iron and binocular magnifier, I wrote a ticket to tech support, hopping to obtain the LEDs reference and... They refused to tell me 🙄...
