Replacing all the LEDs individually is time consuming and there's a bit of a learning curve involved, plus you'd need a big bag of donor lens (I have thousands). Upside to this is that it costs virtually nothing. Downside is that it takes a lot of time and precision alignment of the donor lens.
Put your model number in the ShopJimmy website, and if they have the strips, you can get them there. They will also have high res scans of the strips so you can often use those numbers to check with Aliexpress if you don't mind waiting 3-4 weeks.
If you do replace the strips, be ****very**** careful putting the screen back in the plastic guides. If one corner is just a smidge over the frame, it will crack when you snap on the outer bezel.
If you do get new strips installed successfully, send me the part number of the power board and I'll tell you how to modify the drive current to the strips that will extend the life of them by at least 4X minimum.

I'd be interested in that lifespan-lengthening mod. Does it work for most/all makes? I'm seeing an increasing number of LED backlight sets with failed LEDs.
