Problem with Denon-Heos-AMP HS1
Cause:
After a factory reset attempt that fails, the following problems occur.
PS
The unit worked just before the factory reset!
Problem:
The device tries to update the firmware automatically (online), but it fails.
The device then flashes red continuously.
According to the service manual, the only option is to load a new factory firmware using a USB dongle.
After many hours of searching the web, I have not been able to find this firmware file.
The service manual refers to an SD (service disk).
The Denon service office does not sell or provide service application software.
I hope for further information/help to solve this problem
Regards Mogens

Sziasztok Urak!
Hozzám került egy ilyen erősítő.A HA1370-es IC rendesen kipukkadt és nem találtam boltot ahonnan lehetne rendelni.
Esetleg valaki tudna segíteni,hogy lehet-e helyettesíteni és ha igen mivel.
Köszönöm
Üdv
Kedves Fórumozók!
Az alábbi aktív sub mélye szól ,bár halk és recseg kicsit, center nagyon halk, többi néma csend.
Van benne egy RSN311W64 B IC, én erre gyanakszok. Találkozott már valaki ilyen hibával, amit javított?
Előre is köszönöm a hozzászólásokat!
SONY STR DE 698 tipusú erősitőn nem lehet BEMENETET választani. Nem reagál egyik kiválasztógombra sem. Próbáltam RESET-elni az interneten megadott módon , de sajnos ugyanaz a helyzet, visszaáll a tiltott állapotba. Vajon elektromechanikai hibája lehet. esetleg valami védelem kapcsolja mindig vissza. Van valakinek valami ötlete ?
