Hi, anyone with experience fixing issues with a B&O MX4200? Over the past month mine has been switching itself to standby more and more frequently. I don't use it as much as I should and the issue seems most common after it's been switched off for several days.
Once switched on the green LED illuminates, then goes red for standby. After waking it up with the remote I had no issues tonight for around 15 minutes before it switched to standby (red LED). It usually wakes up again using the remote but tonight refused after a couple of attempts (no LED illumination).
Found a repair video for the MX4002 (dry solder joint on J5), but the PCBs are very different to the MX4200. I had a good look on the board with the PSU input on but couldn't see any obvious dry solder joints or bulging caps. I gave it a decent clean out whilst I had it opened up as it was very dusty and it was fine for the 90 minutes I tested it after.
Just wondering if anyone else has had this issue and can suggest a fix for if it persists - appreciate it could be any number of things!
Thanks in advance.
