Oh and by the way if my post has been at all helpfull
please press the little THANKS tab
Look here :measuring this voltages,If stabilizer ST2L05-3300 ( 1,25V ) not working good ,it can destroy the DSP.
If the stabilizer is changed and the DSP also changed ,and still not working then must change the CS42438 also.
You can visualized the stabilizer voltage with oscilloscope.
Send us results.

First change the stabilizer and do not solder the DSP,check the voltages 1,25V and 3,3V also and check also with oscilloscope ,the line must be stable without any noise when visulizing with scope,if it's ok only after that solder the new DSP.And if still not work then change the CS42438.

i repaired one with no tone. the solution from attilaa0 works. I replaced all 3 components

Hi everybody! Can you plz share a dump for 24LC256? my amp's DSP does restart 13 times a second, because DSP issues no watchdog signal to voltage regulator, thus the regulator forces reset. I had a look at EEPROM and there were almost only FF's, and, because DSP starts from EEPROM, I'm sure the dump might be damaged.

Hi!I don't know what model you have,i have 2 different dump.Trie it and send me result.
Hello guys, I have the same problem as OP. I wanted to order replacement chips, but the ones I find on eBay/AliExpress are with different numbers. But does it even matter? Please see image.
