wszedłem w menu serwisowe i taki błąd mi się pokazał:
DST: 770F10FF90
T1 BUS: BOOT
EEPROM BUS: OK
więc nie ma komunikacji między procesorami (IC221) and TI (DSP, IC241)?

Hello!

Try to heat up the DSP chip IC241 with a hot air to about 50-60°C and turn on the receiver while the chip is still warm.
Check if the same error is still detected.

Check IC27 (NJM4565) on the bottom face of the main board/analog signal (it is the one on the bottom of the equipment)

Co jest źródłem dźwięku ? Jeżeli HDMI to sprawdź DSP czy się grzeje. Jeżeli tak to zamrażacz lub odwrotnie sprężone powietrze i ochładzasz układ aż pojawi się dźwięk. Zdiagnozujesz uszkodzenie DSP.

źródłem dźwięku był:
laptop,telefon rca>jack
telewizor hdmi (brak obrazu)
tylko szum słychać nic więcej
podgrzewanie i ochładzanie nic nie dało
dsp zmieniła się temperatura o 5 stopni
