Re: [slim] SB3 reboots after soon after starting to play
Philippe, Many thanks for your good advice, and especially for the list of part numbers very helpful. I'll start looking for suitable caps after Xmas, and perhaps try to find Ta or NbO2 types with the same footprints, as they should last longer than Al electrolytics. I'll report back when the job's done. Season's Greetings to everyone!

I understand, but, from my experience it's a 100% proven cause on 4 SB3 that had this symptom (I saved 3 but on one I stupidly damaged was the CPU, but I still fixed the MB and verified it). One tip: because removing capacitor can be done using the "twisting method", it takes literally 5 minutes to remove them. I think you likely can take a pass on the 63V which is for the VFD, then you can replace the set close to the DC/DC, then the set close to the DAC if it still does not work. I use solder paste, put the capacitors back one by one, hold them with a plier, solder one leg pretty hot (300°C) to make it quick and handle the thermal capacity of the ground plane connected ones, then move to next one. Each capacitor is a 2 minutes job, so it's 1 hour in total. You might easily spend more time in investigation, unfortunately LMS 7.7, 7.8 and 7.9 - 5xRadio, 3xBoom, 4xDuet, 1xTouch, 1 SB2.

Oh boy, that's going to take some time, sourcing 23 SMD electros that are drop-in replacements (physically + electrically) for all those on the main SB3 PCA. The two THD caps will be easier. I might hook a 0R1 non-inductive resistor in series with the external supply first, and monitor the R's voltage with a DSO in peak-detect mode, to see if current spikes are indeed a symptom.

Some other threads suggest replacing only a few capacitors (@ralphy made suggestions). I personally replaced them all all 3 times, at the end of the day it's not too long and some are only accessible when surroundings ones are removed, so I took the brute force approach. Current draw is probably going through peaks that you don't see unless you've use a scope, so the voltage drops is sudden if the capacitors are not doing their job and the reboot happens, I assume LMS 7.7, 7.8 and 7.9 - 5xRadio, 3xBoom, 4xDuet, 1xTouch, 1 SB2.

Re: [slim] SB3 reboots after soon after starting to play
Have you tried with a PSU from one of the other SB3s. I would say that for a behaviour like that, more often than not a failing PSU is the culprit. alfista's Profile: http://forums.slimdevices.com/member.php?userid=32396 View this thread: http://forums.slimdevices.com/showthread.php?t=107412 ___ discuss mailing list discuss@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/discuss

[slim] SB3 reboots after soon after starting to play
HI there. I'm sure I have seen subjects about this, but my quick search did not return useful info. I was given a SD squeezebox 3 (ether/wifi) some time ago and decided to power it up. It has a fantastic looking VFD screen. Problem, it reboots or locks up a few seconds after starting to play anything. It's not the PSU, it checks ok and the SB3 reboots also with another PSU. I did a xilinx reset. I did not reinstall firmware (137) or reset factory settings. It's not the wifi card: the SB3 reboots the same with wifi card installed or not. I've pushed on the mezzanine connector, not that it looked any loose before that. It gets a DHCP address, so I suppose it has not forgotten its MAC address. On cursory examination, I didn't see a blown capacitor or anything strange. I've used analog out only (and not for long...) Does this behavior reminds anyone of a known defect?
