    Why Mess With LED Drivers? Get Strip Lights.

    I've been replacing all of the fluorescent lights in my rv with little LED 12v strip lights, and a thought occurred (yeah, I know... an unusual thing for me).

    Why do we work so hard to get the LED driver circuitry working again on tv's, when we could just replace the entire function (LED's, driver boards, etc) with some of the strips? I got a 5m roll of them (from China, of course) for less than $10.

    I see a LOT of questions on here about getting the backlighting to work again on various tv's, so it's gotta be a big problem-area. When I was trying to find some replacement LED's for a Seiki tv, the best I could find was $45 for a single strip of 8 of them.... and a lot of places didn't have any stock.

    I'm sure you'd have to match color temperature, lumens, etc, but how bad could it be?

    Whatcha Think?

    But you cannot adjust the backlight level unless you modify or add circuit for that function, you can mod the circuit to turn the LED ON/OFF.
    Since the LED strip does not have diffuser LENS for each LED, you can see the light bands on the screen.
    For example:

      Yeah, you're right. I didn't think too far into the idea at the time.

      However, I did happen to run across some stuff on the Inet (Instructibles, etc). One guy had an O'scope with failed backlite, and he stuck some LEDs in there. Another showed a pc monitor, but you could kinda see the bright bands. Not good for quality tv, but what the heck. Guess it might work if one wanted to put enough effort into it, or maybe just to say: "Hey! It works!".

      I'm kinda like that. I built a sat-tv receiver & antenna from scratch, way back when HBO/etc weren't scrambled. Got a picture to prove it worked, then lost interest... til MDS microwave came along for metro areas.

        IMAC A1418 / MB: 820-00430-a / does not turn on, Lights 3 of the 4 LEDs and turns off.
        by gabrielA7
        Does not turn on, lights 3 of the 4 LEDs and turns off and stays like this, presses the power and repeats.
        I saw that the room LED lights up only when the screen is connected, so quiet.

        We have all the power supplies, even processor, 1.8V
        One thing I found strange, it has a very low resistance in the Vcore is giving 1 Ohm , work with notes and such, I know that this is normal in some processors but with this resistance only take video card so found it strange.

        I suspect that there may be some leak in the processor.
        Anyway, when I press the power, it...

        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 🙄...

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

        Need help replacing led strip on Iiyama Prolite XUB2390HS monitor
        by mikey5791
        Hi,
        Got this working ips led monitor by the brand of
        Iiyama Prolite XUB2390HS presumably a 23 inch type given to me with suspected bad led backlight. To test it, i unplugged the bad flat ribbon type connector and plugged it a good flat ribbon led connector scrapped from a HP Pavillion 27cw (led strip with 60 led). Good news is the HP led strip lights up but not fully, in between there are about 15 unlit leds.(as picture attached shows).

        Fyi, i had not opened and removed the old bad led strip. My question is whether is it possible to cut some of the extra leds(say...

        Replaced LED. Lights on its own but not in the strip
        by RooTV
        I had 1 LED out on a Bauhn ATVS58-0516.

        I had some spares so I took one of an old strip (after making sure it worked) and took the bad one off the strip.

        I then put the replacement one on the strip.

        Now all the original lights light up (same as before) but the new one doesnt.

        I put the backlight tester on each side of the replacement and it lights up no problem.

        What am I doing wrong? This is the first time I have tried this procedure and I thought it went well.
