So, I finally was able to procure an 840AV - the seller telling me, he recapped it - to no avail.
No offence, when I did have a look the solder job was not optimal.
De-capping, spending a night in IPA, recapped ... connected - the 840 sprung to life, chimed and presented me with a disc symbol and a question mark .
So far so good ... after that, I noted that it does not boot "each time", sometimes you have to multiple start - recently mostly, it starts to chime for "1/2s" and then stops.
Any ideas other than then PSU? The board actually is very clean and I didn't see any bad traces.
(Which PSU can be used to test? the PM8100 is using the same - any models with maybe the same connector?)
