Plasma Panel Storage

[gearyt]

I was asked a question about storing plasma's on their backs
so I contacted our Panasonic Rep.. His reply...

Yes, maybe not immediate but the panels flex when flat and the center pixels become fatigued and will eventually lose colorimetry compared to the surrounding pixels.
The boxes are not rated for horizontal stacking which is also a concern.
The factory specifically specifies vertical storage and transport except for short periods of time as when installing slot boards.
