I have enough sense to have tarps protecting stuff. Could have been surface water. My back yard occasionally floods too--it's a very pleasant place but is a former pond bottom.

I kind of think the water affected the LCD screens. >Is there any way to get them LCD screens to work (other than replacing >them)? No. LCD panels are not hermitically sealed. If it were sealed, the glass would bulge when the panel becomes hot. There is a tiny hole, usually near the bottom of the screen, to equalize the air pressure on both sides of the glass. If you immerse the panel in cold water, the air inside the glass screen will contract, causing a partial vacuum, which will suck the water into the panel. If you remove the frame from the panel, you can see the water inside the panel. I had the bright idea of heating the panel to build up internal air pressure and thus push the water out of the panel. That didn't work. I also tried using a vacuum pump on the outside to help suck out the water, but that also failed. Best results were to attach something that wicks water (cotton balls, rice, desiccant) at the hole, to suck out the water via capillary action. Even so, I was only able to extract a tiny amount of water, leaving most of it inside the panel. When the price of panels dropped dramatically, I gave up on trying to fix these. The GPS and radio scanner probably have corrosion damaged PCB traces. If you can find the damage and repair the traces, both can be fixed. -- 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 |
