If holding the power button does not force the device to turn off, there is probably something malfunctioning at a very low level. It's unfortunate if this happens out of warranty, but regardless of tricks to recover, the device should probably be considered broken.
There is a special challenge with e-ink devices. If it becomes truly unresponsive, you can force it to shut down with the long hold of the power button. However, the screen won't actually change!. If the light is off, the only thing you can do is take it on faith that it's shutting down, wait 10 seconds or so, then try turning it on again.
