Denon-Heos-AMP HS1 flashes red continuously after a factory reset that fails.
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

Lorta 75U-202S orosz erôsitô búg
Sziasztok Lorta (Amfiton klon) órosz erositoben egyik oldalaban kimentek a veg es a meghajto tranzisztorok, kicsereltem oket, de most teljes hangerovel búg, a zene pedig alig fellelheto benne.De ez mindkét oldalon! Tápja jó: +/-33V. Probara tapelko csere, gretz csere tovabbra is búg. A javitott oldalon minden kiselkót cseréltem.Tranzisztorok nem melegszenek. A bemeneti koax kabel halojan keresztul kapja a 0-at! (kábelspórolás?), ha ezt kicinezem a vedelem nem kapcsolja relen keresztul a hangszorokat. Ha csak a koax belsojet cinezem ki akkor is bug. Ha pincettaval hozzaerek az egyik TO-92-es tranzisztor kolektorahoz, egeszen elhalkul a bugas, de viszont errol a labrol csak 1 db ellenallas megy tovabb, de az ellenallas masik labanal mar nem halkul el a bugas. Más: Eloerosito potira (tobbfokozatú ellenallaskapcsoló) nem reagal a hangerô, de szerintem ez mar masik problema. Na akkor most akkor mi baja lehet?

Hi mindenkinek! Eme szörnyeteg kapcsolási rajzát keresem, közel annyi alkatrész van benne mint az USS Enterprise űrhajón ami nem is lenne baj ha működne:). Fél nap potyára guglizás után gondoltam még itt megpróbálom, hátha valaki épp egy ilyen dokumentumot őrizget. Előre is Köszi. Üdv.
