Hi guys. The problem with the receiver is as follows: - there is no sound output to the speakers. There is sound when PURE DIRECT is pressed. Diagnosis( info+tone+main zone) showed that no checksum and version DSP1 . DSP2 - OK. What could be? Chipboard DSP1 supply voltage is normal. Need a chipboard DSP1 replacement? disk.yandex.ru/i/p-YISDx-Fr39Og Service manual

Hi . Heating the chip did nothing.
Made it similar to this video.

Usually the BGA ICs have the solder ball issues.

cant you see serial output to check if system is booting? maybe it cant boot because of FW issue?
