I have and found most of the voltages as indicated on the circuit diagram, till op amp M 5218P; are near those specifed. The output on the centre of the two power transistors of both the channels are also alright.
While looking at the voltages on test points as mentioned on the page 7 for setting up quiscent current, these cannot be set.
Bit of history, the amplifier was lying unused for long time. Nothing in it has burnt. It was never opened earlier than this time, couple of days back.

While I was probing for voltages with DMM, with probe on collector of TR413 one of the fuses blew up. Later same thing happened on the other channel as well.
With the above as background can a Good Samaritan figure out feasibility of repair.

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. Adott egy DENON PMA-260 eroszíto..Kaptam...Sajnois nem kapcsol be, megmértem a tekercset sajnos nem kap áranot. Esetleg valakinek kapcsolási rajz? Koszonom szépen
Sziasztok!
A cím már sokat elárul, és gondolom sokan mondják majd azt hogy NEM!
A helyzet a következő, megkaptam ezt a rettenetet több más készülékkel együtt, hogy villámcsapás érte.
Belenézve megint elment a kedvem mindentől.
Én K.O.-ra gyanakszom, mert bedugva/bekapcsolva semmit nem csinál.
Készenléti trafó megy, 5V körüli feszültség kijön belőle, de semmi több.
Én processzorra gyanakszom, mert egy led sem nyikkan meg rajta...
Érdemes vele tovább foglalkozni?
Üdv,
Krisztián
