ok, so I guess I have to buy a new one with a better cover.. I don't remember any pressure, hits etc but if you say so..

so, what's the prognosis?

The straight lines could be controller failure. What indicates a broken substrate are the curved lines across parts of the screen, which only happen with a break in the glass substrate.

I can't see the impact point though - often in these cases there are radiating curves. So perhaps the break was through a twisting action instead of an impact.

there hasn't been an impact point

don't know what could it be.. could it be just some kind of electric "thing" that broke everything (screen and motherboard together)?

No, the picture you posted is definitely a broken substrate. If you disassemble the unit, you will be able to see the broken glass. I see the curves in the picture, and it looks just like the screen on my husband's broken Kindle, which I did disassemble back in 2009.

As I said, it didn't look like a point impact to me, so perhaps it was a twisting action.

I really don't think it was just plugging it in to power that broke things. Unless you plugged it into 240V directly

That would cook any gadget this side of the pond!

as I said the problem happened after that plug-in into the wall charger. Even if it is the screen, how is it possible that at the same time both the screen and the motherboard got stuck? I'm more and more thinking about some "electric - mess " happened.. it was for sure not 240V

Surprisingly many (NOT all) electronics/small appliances are rated for 110-240V so pretty good odds you wouldn't cook it with 240V. Very handy when going overseas to only need an adapter for the plug end rather than a converter to take the voltage down.

locus · 01-13-2016, 04:13 PM

well I guess I cooked it with less, I had a special recipe

Once the screen substrate has fractured it will basically keep whatever image was on it when it broke (won't change when you do something that should result in a different screen i.e. if you hit a home button). E-ink maintains a static state (image) without any continuous input whereas an LED screen requires constant refresh (redrawing) of the image or else it disappears. You may get part of the screen changing to lines after you broke it because part may still be getting signals to change where most of the screen isn't. The curved line in the image is the giveaway that the substrate it broke. Not sure if the device can detect a broken screen and go into an error state, but that could explain flashing -- is it the screen flashing or a power light?

interesting explanation. It's just the power light flashing and as I said I'm unable to see the Kindle's content via my PC.

Is it still under warranty?
If yes, contact Amazon.

unfortunately not :/

In that case,
I don't think there is much you can do.
However, Amazon may still be running that special where they will pay $5 for a non working kindle and $20 towards a new Kindle.
