Kindle 10th Generation Backlight dead

Well, the model # for the 10th generation (barely readable with a magnifying glass) is, or seems to be: PQ94WIF (purchased in 2019).

Model # for the older one (5th Generation?) is EY21 or FY21. Nearly impossible to read.

The serial number prefix for the 10th Generation is G000T6

Your model is known as a Paperwhite 4 or a Paperwhite 10th generation (not to be confused with a Paperwhite 4th Gen model).

The EY21 is a Paperwhite (#1 I think) 5th Generation model.

I would be very surprised if the screens were compatible as Kindles change a lot between Generations and more so if there is a gap of 2 or 3 generations between them, but I may be wrong.

I can't find any parts for your model but an option to consider perhaps and if the price suits is to purchase a donor tablet and scavenge the parts from it. (example only).

I also couldn't find a screen replacement video or guide for your model, but here's a video that shows how to replace the battery which may help, at least as far as getting into the tablet.

Around 1981 I had the idea of producing something like Kindle, when I was working with EPROMS. The idea is that you wouldn’t have the inconvenience of buying books all the time. But the fact that these devices break down and can’t be repaired conveniently, and cost an arm and a leg, it was probably cheaper to just buy books. At least they don’t stop working, though they will fall apart after 5 to 10 decades. I strongly suspect that this programmed obsolescence exists just to drive inflation, because without it we’d have a deflationary economy and the banking system wouldn’t be able to strangle the public. I just don’t feel like buying more of this expensive crap.

Libraries are cheaper still ;-)
