Bugzilla – Bug 15305
backlight comes on while off with "Screen off" as screensaver
Last modified: 2010-04-08 17:25:22 UTC
PB2 currently at 7.5.0 r8212, using MySB.com. My When off screensaver is "Screen off". The screen always goes completely dark when I turn the player off with the onscreen power button on the home screen. But usually within several hours the screen goes to "black but on" -- nothing on the display, but a very dim backlight, as for an LED screen that is on and attempting to display an all-black fullscreen image. This has been the case for a while now (several weeks at least). Sorry for not reporting it sooner.
I don't know when the screen last "lit up" when off, but /var/log/messages has many sets of lines like these Dec 14 16:20:16 squeezeplay: INFO net.comet - Comet.lua:627 Comet {oldbox}: _handshake error: HTTP/1.1 401 Unauthorized Dec 14 16:20:16 squeezeplay: INFO net.comet - Comet.lua:997 Comet {oldbox}: handleAdvice state=CONNECTING Dec 14 16:20:16 squeezeplay: INFO squeezebox.server - SlimServer.lua:745 failed auth.

Perhaps at some point my fab4 is giving up on MySB.com and trying to fall back to a local server, and that's triggering the problem?
I think I've seen similar behaviour when the update screen was popped while the device was powered off. Does this sound familiar?
No, I'm afraid not. It happened again last night / today -- got home from work and the backlight is on. No announcement of a software update, and Settings > Advanced > Software only offers "Cancel". I'll see if I can dig up a spare SD card to capture more from syslog.
Peter - there was a bad firmware being pushed out yesterday (one based on 7.4 code). Please update to 8224 and report back. Thanks!
OK, I'm on 8224 now, and have manually tweaked syslog so I should get enough data (see bug 15311 -- even with the SD card, fab4 wasn't keeping more than about 1.5 hours of syslog messages). I'll keep you updated.
Since updating to r8224, I got over 30 hours without seeing the problem, which is far better than I've seen in a while, so I think this may be fixed. I'll reopen if I see the problem again.
This bug has been marked fixed in a released version of Squeezebox Server or the accompanying firmware or mysqueezebox.com release. If you are still seeing this issue, please let us know!
