Köszönöm.

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

Hozzám került egy Nikko R400 rádió erősítő.Hibás volt az STK4171X. Cseréltem, de a tápellátásban van hiba. Jól jönne egy rajz, hogy tudjam a feszültség értékeket. Minden ötlet jól jön.
Sziasztok!
Vettem A Vaterán 2 db komolynak tűnő hangfalat amiben szalagsugárzó van. Sajnos az egyik szalagsugárzó hibás lett a valamikori tárolási körülmények miatt. A pára tönkretette a fóliát. Ennek a javításához kérek tőletek ötleteket, mert új nincs. A 3. képen látszik a hőre lágyuló fölián a hibás rész. (Forrasztás kizárva.)
Köszönettel Karesz.
