    Help Finding a Replacement LED Strip

    Hello Everyone

    I've spent hours looking at Chinese (mainly) websites offering replacement LED strips for backlighting monitors, TVs etc but I can't find one to replace mine.

    Mine goes into a BENQ GC2870, it contains 32 LEDs and is 355mm long. It is marked E117098 94V-0 on the front and NLM144LL077BDBKALB00751R901LGA on the back. I have attached some pix in case that helps.

    If the matrix in it is M280HKJ-L50, then such a backlight.

      Really kind, much appreciate your help.

      I've been on to their website but I don't think they've got any stock which doesn't matter because I can't find any way to pay them. Spent about an hour trying to setup an Alipay account (I'm in the UK) without success.

      I think what I'll try and work out is how to use a strip of the right length and width (355mm & 5mm) even if it has more LEDs.

      Wish me luck and thanks again for your help.

        More, fewer LEDs - it may not turn on, the led driver will not work correctly (current protection)
        There, in my opinion, 4 channels of 8 led.

          I think the strips I am thinking of come with a driver board which needs a 12VDC supply and which takes the place of the integrated LED driver circuitry within the monitor?

          I would need to find a place from which to tap a 12VDC supply and then use double sided tape to attach the replacement driver board to the monitor chassis.

          I think

          I don't know how I would integrate the panel controls that control the picture, brightness etc. Another problem!

            Meant to add that you are right about the 4 banks of 8 LEDs making up the 32 in total.
