o3DS don't work

[Sinore]

Good afternoon. Problem with 3DS

Today, during the game, the console abruptly turned off and after that refuses to start normally. First, the blue light came out, and the console turned off. After reinstalling the boot files and deleting the Luma settings, seemed to start up, but after half an hour - hour, turned off again. Now nothing comes out, only a black screen and blue light , after a sharp sound and shutdown. Tried all the same as before - does not help.

What I have tried:
1. Formatted the SD card
2. Tried to use another card
3. Installed the latest version of Luma
4. Installed Luma 7.1 (gives an error)
5. Deleted the Luma settings on the SD card. The console turned on, asked to configure Luma, and then turned off again

I apologize in advance for my poor knowledge of English.

Probably hardware damage (ribbon cables to the upper screen starting to tear). Software problems don't give a popping sound.
Open the 3DS only partially (less than 90° angle), sometimes this works.

In the long run the only real fix is replacing upper screen and/or loudspeaker cable.
