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

DENON PMA480R erősitőhöz keresek kapcsolási rajzott
Sziasztok!
Áram alá helyezve a bekapcsoló gomb zölden világít, de másra nem hajlandó. Tápegység jónak tűnik!. Mintha processzor hibás lenne. A kijelző is sötét. Feszt kap. Javított már sikeresen valaki ilyet? Köszönöm!

Üdv.Ezen típusú erősítőnek (Denon PMA-757)vagy(Denon PMA-777)kellene a kapcsrajza mert a felelőtlenségemnek köszönhetően tönkrement az egyik oldali végfoka.A két végtranzisztor (2SA1303,2SC3284)
ment zárlatba meg 5db ellenállás szakadt meg.A multkor vettem bele a HQ-tól és az is szintén (sanken) gyártmányú volt mint az eredetiek.Átmértem a panelt majd kicseréltem a tönkrement alkatrészeket és fejhallgatóval índítottam.Be is indult szépen majd rákötöttem hangfalakra negyed hangnál és kikapcsolt loudness és hangszín mellett szólt egyformán de ahogy rákapcsoltam a loudness gombot abban a pillanatban zárlatba mentek az új tranyók és füst szált fel belőle.De nem értem mi okozhatta főleg ilyen kis hangerőnél?Kérem ha valakinek van valami használható ötlete azt is szívesen venném mert nem szeretném tucat számra venni a tranzisztorokat bele.Válaszát erlőre is köszönöm... Tomi
