The phone appeared >to work, (made sounds), but without the screen it was useless.   You keep saying "dead". I can usually tell what killed the display if you would kindly provide a better description.   >I had a similar experience with a GPS, which got soaked.   That could have been saved. The problem is that standing water is sucked into the display through the pressure relief hole when the temperature of the panel drops. For example, if you warm up a display to something above ambient, such as 30C, and then dump it into 12C water, the liquid and air inside the panel will contract, creating a partial vacuum, and sucking in the standing water. You can heat up the panel in the hope that the water remains near the point of entry, but I haven't had much luck doing that.   What does work is turning the LCD panel upside down. For some dumb reason, the designers of most (not all) LCD panels put the pressure relief hole at the bottom of the display. When even splashed with water, the water will puddle near the bottom of the panel, and eventually be sucked in by the partial vacuum. Turning the display upside-down moves the puddle to where it can do less damage. However, there's a problem. If the panel has a metal frame, as in most laptops and LCD monitors, the water puddle will be trapped between the glass panel and the metal frame. I don't have a solution for this situation, except to turn the panel upside down while drying and hope for the best. Whatever you do, don't let the panel cool down until you're sure all the water has been cleared from the pressure relief hole (with an air compressor).   >Why dont they put some silicone sealer on the edges of those LCD >screens? Or something that will prevent water from getting into them?   Because changes in altitude, air pressure, and temperature will cause the glass panel to either expand or cave in. If thin enough, it will probably crack. Small changes in air pressure over large panels such as big LCD monitors will result in quite a few pounds of pressure on the display. A 0.1 psi change in air pressure, across my 270 sq-in LCD display, will exert 27 lbs of force over the entire glass area. Putting that much weight on thin glass will bend and possibly break it. So, there has to be a method of equalizing the internal pressure with the external air pressure, which is the pressure relief hole. The problem is less with small displays, but pressure relief holes are still used quite often.   -- Jeff Liebermann jeffl@cruzio.com 150 Felker St #D http://www.LearnByDestroying.com Santa Cruz CA 95060 http://802.11junk.com Skype: JeffLiebermann AE6KS 831-336-2558

Unicorns will go only to virgins - quite unlikely either with Olds... or with Faux Spews.   And, with that in mind, consider that Faux Spews is not an actual news organization, but an entertainment organization. They are unencumbered by any necessity as truth-bearers or tellers, as long as they continue to sell Viagra, Depends, 23 & Me, Ace Hardware and so forth. Deplorables make a safe and reliable audience, don't need any subtlety, nor any facts.   And, consider the side benefit is that they get to make US Foreign Policy as a side job!   Peter Wieck Melrose Park, PA

"pfjw@aol.com" <peterwieck33@gmail.com>: Mar 18 04:43AM -0700 As long as you understand that so-called "mosquito traps" based only on light do not actually attract mosquitoes, you will find that any light will do.   The shocking trap has been demonstrated to attract primarily beneficial insects. From: https://www.mosquito.org/page/faq   Do Bug-Zappers work? Black light insect electrocution devices (Bug Zappers, etc.) are purchased in huge quantities by homeowners due to their demonstrated ability to attract and kill thousands of insects over a 24 hr. period. One industry representative estimates that over 1.75 million of these devices are purchased annually in the U.S. But do they really control pest insects? Bug zappers do indeed kill some mosquitoes. However, the only two controlled studies conducted to date by independent investigators at the University of Notre Dame showed that mosquitoes comprised merely 4.1% and 6.4% respectively of the daily catch over an entire season. Even more important was the finding in both studies that there was no significant difference in the number of mosquitoes found in yards with or without bug zappers. What is particularly disconcerting, however, is the number of non-pest insects that comprise the vast majority of trap catch. Many of these insects are beneficial predators on other insect pests. They in turn constitute a major part of the diet of many songbirds. Indeed, reduced numbers of moth and beetle prey species have contributed significantly to the decline of songbird populations in many affluent suburbs. Insect electrocution devices undoubtedly bear some responsibility for this phenomenon. Mosquitoes continue to be more attracted to humans than to the devices. One study conducted in homeowners' backyards showed that of the insects killed by these devices, only 0.13% were female mosquitoes. An estimated 71 billion to 350 billion beneficial insects may be killed annually in the United States by these electrocuting devices.   Let your conscience be your guide.   Peter Wieck Melrose Park, PA
