MadskpThen I used the Beo4 to press SHIFT 9 0 2 5 8 and was surprised when this opened the Service Menu – very strange because this is not how the Service Manual says that the Service Menu is entered. (The manual says MENU GO, then 0 0 GO.)
(The SHIFT 9 0 2 5 8 sequence is actually the button sequence for Service Mode on a BeoSound 1, and possibly other systems).
Great work thinking out of the box, but very weird that this works. Maybe different software version did change something, but nok very smart in regards to servicing.
On thing that came to mind in this regard is, could it have been updated with a wrong software? Do you have a history of it being used before not working anymore?
NVEM: TP_MODULE_HW_ERROR_APOS (keeps re-appearing, even if I manually clear error)
VMEM: As above plus MLSL_STATUS_ERROR (VMEM errors are cleared by unplugging)
I also looked in the BS4 servicemanual but could not find anything either. Then I tried a google search, and some references to the Beocenter 2 servicemanual came up.
Looking at that the MLSL_STATUS_ERROR seems to be ML related, but have different error types, so you might want to look that up to see if you can spot anything usefull.
Also a thread here with a BC2 with a similar error message, but no solution https://archivedforum2.beoworld.org/forums/t/36631.aspx
Being in the ML mindset I would suggest taking a good look at the ML connector to see if any legs are bent and touching each other. If not a survey of the ribbon cables between the socket board and the main board could be worth doing.
