Love your lightbulb argument ... the problem is though there is another factor regarding the libby ... the very real chance that whichever way you do things, the screen will STILL outlast the rest of the libby anyway and/or that a blown backlight tube will be the least of your worries (you're more likely to damage the screen or blow the inverter or something like that). Put another way, in the case of the lightbulb the thing thats likely to render the whole lot useless FIRST is the thing you want to preserve ... in the lightbulb this is the filament however in the libby this is NOT the backlight tube. If thats the case then you'd be better off doing whichever is more convenient, in this case keeping the screen on. Now I dunno about the rest of you but I can't say I've ever seen a blown or degradated backlight (at least not the cold tube type ... seen some EL backlights go though) and I've seen a reasonable number of quite old LCDs. Anyways thats my $0.02 ... - Raymond --- /~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~\ | | "Does fuzzy logic tickle?" | | ___ | "My HDD has no reverse.
