I also have a Horizon with a backlight issue. I took it apart and found the part numbers (panel: LTA400FJ01, LED strip: 2015SLS40_FCOM_BNO_REV0.5_150902), but I haven’t been able to find a supplier since these seem to be custom parts. So now I’m stuck and considering replacing the LEDs instead.
I was quoted £1,400 for the repair, so your price sounds pretty good!
How did you identify the correct type of LED?
Best,
Stefan
