Hello!

Try to heat up the DSP chip IC241 with a hot air gun to about 70°C and turn on the receiver while the chip is hot.
If the sound returns, the DSP chip is damaged and needs to be replaced.

podgrzewałem DSP chip IC241 i dźwięku nie ma dalej. Poprawiłem na wszystkich układach luty

What does that mean?
If these are measurements, the measurement units are missing.
If you write just "11,87" it could mean 11.87µF, 11.78A, 11.78MΩ, 11.78mH, 11.78V, 11.78kg or anything else. Always write the measurement units to make the things clear. Also edit your first post with the units.
