    Corsair K70 LUX RGB dying LEDs
    by Pipolups
    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 🙄...

    Insignia NS-37D20SNA14 intermittent LEDs
    by THE GTC
    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...

    Replacing Mode Indicator LEDs
    by VitalComputing
    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...

    just a quick question do all qled leds appear blue when fault finding ?
    by jimbofz
    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?

    Finding the wrong part at a loooong led strip, part works fine, part flickers, all parallel...

    Hi There!
    I'm trying to help my friend who owns a restaurant be just bought.
    He has a very long LED strip running along all the walls and columns. The strip is attached facing down 2in above the floor, using a wall panel that ends in a metal rail that finishes the panel underneath
    It's stuck using, I guess, the 2 sided tape that comes with the strip
    The issue is that like 1/2 of the full length, including 1/2 one wall, another entire wall, and one column, flickers after 4 or 5 minutes ON. Particularly it flashes staying OFF most of the time and flashing ON for 1 tenth...
