Nedd to worry about display "burn in"?

[Larry Truesdale]

Hello,

I like the display on my squeezebox at the highest brightness level.
Should I worry about "burn in" or "fading" over time? Would it be
better to set the standby brightness to something lower to prolong the
life of the display?

Thanks,

Larry

Larry,

Burn-in is indeed a characteristic of VFDs but we have not had any
reports of it in SLIMP3/Squeezebox with over 3yrs worth of hardware in
the field. So I think the lifetime is quite long...

Of course it depends on what you've got displayed, and how brightly. To
maximize the lifetime you might want to use the 3/4 brightness level or
use the lineX screensaver. However I don't have any indication that
burn-in is really a practical concern for the displays we're using, but
perhaps it's too early.

I'll ask our vendor though...

Thanks for the info. I'll look forward to hearing what the vendor says.

Well, I have a SB3 that I bought in December that shows clear display burn-in. I have it configured to show the clock when it's off, usually at brightness 4 or 3 (and brightness 1 from midnight to 06:30).

You can see the burn-in where the clock digits are whenever large fields of pixels are lit, as when you adjust the volume or when the boot-up banner comes on.

It's pretty disappointing.

Can you post a pic? Thankfully, I don't see that on any of mine. Nor my
SliMP3 which I've had for two years and a SB1 too even. If it's bad enough
I would expect SlimDevices to take care of you (not like the mafia).

It's hard to photograph, but you can see it in this picture: http://topanga.ca.us/burn-in.jpeg

And yeah, the aluminum faceplate fell off when I picked it up to position it for this photograph. I tried putting it back on but I just ended up denting it. I fear my nice SB3 is ruined...

and that is what support (AT) slimdevices (DOT) com is for.
you'd be the first in many years of VFD displays and SD products to
suffer burn-in. I'm sure they'll want to hear from you directly.

I sent them email already. I don't suppose I'll hear from them until next week, though.

I'm pretty sure it's burn-in from the clock. In the dark pattern you can see the colon and vague outlines of what are probably the numbers. And the position of the clock digits lines up perfectly with the darkened area on the display. I've seen vacuum fluorescents burn-in before, but never this quickly/easily. I just checked my SB2, which is older and actually has the clock on more because I don't have AutoDim set to dim it at night.

In my experience ... VFD's will loose luminosity as they age - same as all other display devices (Barring LCD ... but they don't emit, just block!).

With this in mind my Squeezebox is setup to power off after 30 mins of inactivity (via a Plugin) and the VFD display on my HTPC will turn off between 00:00 and 08:00.

OK, that doesn't look like burn-in to me. It's more like burn-out. The
places that are on more frequently are slightly dimmer.
