      Thanks for the link. I think there is also another type of leds that is used on LG, 6v. Do you have a link for that?

          As so far as colour goes...I think WHITE is the standard colour for LED backlights for TVs and Monitors.....Some displays like temperature guns and other Instrumentation equipment, where you have to read off a panel, use BLUE LEDs for their backlights.

            Re: LED types?

            sorry i should of worded the above post better regarding colour, i see some list cool white, warm white, etc etc its just which one but as you say looking at the panel specs or led strip it self may give a indication on which type is fitted

              Yes...I would go for the WARM white though, if I had to make a guess.

                anyone know if the shopjimmy led strips are new or pulled from smashed screen sets i was just curious as if pulled from sets these may fail shortly after fitting hence i would rather buy the leds and replace all in one go yes takes extra time but should last longer if backlight etc turned down

                  Re: LED types?

                  So far I have been lucky. In that I have repaired all of my backlight issues using the 'ReeceyBurger123 Stacking Method' from LEDs salvaged from TVs with broken screens. I would turn down the backlight setting to 70% and return to owner. Even with LG edge backlights. So far I've had no call backs. I never had the cause to buy 'new' LEDs, thus far.

                    Cool white I think is what you want. They are on the bluer side. Warm white are on the yellow side. Color match seems to be a problem though. I have bought two batches and one was a good match and the other was noticeably yellower. Also note that anode and cathode can be reversed. At least some Samsung have there anode on small pad.
                    I assume no responsibility for any stupid suggestions I might post.

                      I use Cool white. The large pad-small pad is also important since the large pad is where the substrate is at for heat dissipation to the copper pad, so make sure to use the correct one, the SAMSUNG LED is the reverse of the LG LED.

                          I use the same method, but I have run out of led's and new vestel strips cost 12$ (10-12 led), with that money i can buy 200 individual leds.

                            I have gotten those above. I found them problematic as the pads are wavy and hard to place without shorting out. You might look at these. https://www.aliexpress.com/item/UNI-...498642457.html Worked good for me but haven't done long test on them yet.

                              I have been using SAMSUNG on the SAMSUNG panel and LG LEDS for other LCD panel and so far so good on both of them but then it may have something to do with setting the backlights @ 60~70% range.

                                I started with the stacking method but then went to replacing individual led's. With just a few different types you can repair a lot of different strips. Plus I get more satisfaction replacing led's instead of whole strips.

                                    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 🙄...

                                    So I use this TV daily as a second monitor for my PC or my Playstation - at one point a few months back I tried to fix the problem - but in the process, I figured out something that works so I haven't posted this for awhile. It is an annoying trick to have to do though, so I decided to post about it to see if anyone could spot what's wrong. It baffles me because it works on it's own half the time.

                                    When I first got this TV, I was told it wouldn't turn on, and of course I did the flashlight test, and the image was there. Also, the red LED on the front indicated that it had power (it...

                                    Hi all,

                                    I have what should be a simple job but is causing me issues. There are three LEDs (yellow, green and red) on the indicator panel of a solar PWM controller and these have broken off. I need to replace them but I am unsure of the voltage drop across these. I don't want to replace with random LEDs in case they blow.

                                    I took one of the LEDs out of circuit, put 19V across it with a 500 ohm resistor in series and there is a drop of about 13V across the LED, and this seems to increase as I increase the input voltage.

                                    I thought I could just put a resistor...

                                    i have replaced many leds strips that have changed blue when they are worn
                                    and the new replacements are perfect white
                                    but when fault finding do quantum leds always look blue?
