Hi-Fi Walker H2 player repair with a problem - overheating and doesn’t turn on.
Noises are heard when shaking. Means components inside have fallen off.

After disassembling, I figured out that the screws were loose.

After unsoldering the battery and de-energizing the player, the battery was soldered back. The player had turned on and the charging cycle was completed correctly.
Because everything started working as it should, I decided not to explore pcb further. Although it is not known what exactly was shorted.

The player was assembled, the screws are tightened with thread lock.
