What causes PDP failure?

[Skipfinder]

Besides the obvious cracked screen, what causes a plasma display panel to fail?
And yes, I'm curious about failure modes of the panel itself.

Re: What causes PDP failure?

There are address drivers bonded along the bottom of the panel: these drive the data onto the panel. When they fail you get stuck lines/blocks. Not repairable. I'd estimate around 90% of panel failures due to this.

There are scan ribbons along one side of the panel: these can de-laminate (extremely common on 2009 and 2010 Samsung sets) causing horizontal lines to appear. Not repairable. I'd estimate <5% of panel failures due to this.

You can get a short between the scan and sustain electrodes, causing the buffer/drive board to fail (extremely common on 2007 Panasonic 1080p plasmas.) Believed not repairable, though I think it may be possible to "blow out" a short, I have not yet tried this theory. I'd estimate <3% of panel failures due to this.

You can get maldischarge due to ion implant damage in the panel. Causing a permanent misdifussion or sparklies which clear after warming up. (Extremely common on LG 2005~2008 plasmas.) Somewhat repairable, but never completely. I'd estimate <2% of panel failures due to this.
