I live far away from US so even if Amazon sends new device and only charges for shipment that would still probably be more expensive than to buy some cheap Chinese device in local store. Is glued corpus really making repair impossible?

Kindles **are** a "cheap Chinese device" -
But I know what you meant, some off-brand e-book reader.
Since it is probably just a throw-away item for you now - try:

You might get lucky and be able to see the problem by eye.
But from the description of how it behaves, I bet the corrosion is between one of the BGA mounted devices and the motherboard.
(Very small clearances, very hard to get even dry air between the device and the board.)
There are (or at least where) board cleaning chemicals that might 'fix' it once you have the board free from everything else.
The really good ones are out-lawed here in the USA, they also kill the user (most often, from cancer).
But in your country (somewhere outside of the USA) .... I have no idea what you might be able to find as "board cleaning chemicals".
Those things might be worth trying.
You might also try packing the motherboard in dry rice and cooking it at 200F for awhile (any temperature below the point of boiling water should be safe for the board and parts).
But don't put too much hope on any of the ideas above being any help.
