Title: Arcam AVR300 bad caps
Post by: Finderbinder on April 11, 2023, 07:10:24 pm

Anyone has a list of electrolytic capacitors (and maybe other components) to be replaced?
Just replaced bad caps in main board but I see some bad ones in other boards too. Disassembling it isn't an easy task. Do not want to disassemble it completely and leave so for a long time while I would be acquiring all necessary caps.

Now it plays analog audio in Direct stereo mode, but no sound in digital mode. However it detects digital signal when I supply it from DVD player ("Audio" changes to "Digital" when I connect cable with digital sound), but still no sound from speakers.

Solved. Issue was with DSP pins - surprise from manufacturer using shitty glue where it shouldn't:
