I purchased this BeoPlay A9 MK2 for cheap, as it had an error with amber blinking lights at startup.
I have measured the drivers, and midrange and tweeters measure within spec, comparing to the MK3 service manual.
The woofer however, measure 6ohm, compared to the 2ohm in the service manual.
Can I trust the MK3 service manual, or did they change drivers between MK2 and 3?
I also measured the NTC resistors, and they all measure 0.6 MOhm, which is higher than the 470 kOhm shown in the MK3 service manual. However as all the NTC resistors measure within +-2% of each other, I don’t think they are the problem, and B&O must have changed the spec on these between MK2 and 3.
Anyone else had this error, that have had success fixing it? It does not make sense to get repaired professionally, as it would be too expensive, and as I only paid 150USD for it, throwing much more money at it, doesn’t make sense, when I working used model goes for 700USD.
