    I have the same problem. I am trying to update the software to see if this fixes it, but don't have a serial port on my laptop. I am running ver 3.7.

    I have the same issue, I can remove the battery to reset, the unit will work for 3-4 minutes, then the unit hangs again.

    I have the same problem. I haven't used the the GPS since Sept. 08.. it worked fine ten. Now Nov 2, 2008 I encountered the same problem (unit locks up and dispalys a fine vertical line on screen) twice within 5 minutes while navigating to a waypoint. Replaced the batteries and the problem was back within 5 minutes while navigating.

    I'd been using my ETrex Legend GPS for more than a year without any problems, and just as you all have described, it locks up where you have to remove the batteries to reset it, and it locks up again within 4-5 minutes or so. I don't know why we would all experience this problem within a couple of weeks of eachother unless it is a software problem. I have a usb to serial adapter, but it's been lost in my move here, so I'm going to have to search for it to see if a software update will fix the problem. It's annoying to say the least especially when I'm geocaching or out on a hike and it blinks out several times like that.

Disable the WAAS on your unit. A new satellite was launched earlier this year and is causing a problem. This is why Garmin issued a new software update version 3.9.
Menu > Setup > System... scroll down to WAAS and disable it. This should get your unit working again but with less accuracy.

Update the software to version 3.9 and leave for about 20 minutes in open area (clear view of sky) so your unit can download the full almanac. This should permanently fix your problem. Once you finish upgrading, go back and enable the WAAS.

to mhotz: You can purchase serial2USB connectors at a computer store. You will have to install the drivers which come with it before it will work. That should solve your upgrade problem.

Wiring diagram

I would have the battery tested. The security alarm normally draws power when the car is not running. If the battery is not fully charged or will not fully charge, the onboard computer and the security system may drain enough power to make a bad battery go dead.
You could check the wires at the fuse block to see if more than one wire is attached to the output side. Most connections are made in the wiring harness and would be difficult to find. Are there any hidden light bulbs that could stay on? Do all the systems on that fuse work properly?

Batt. installed started fine now will turn over but not start

Sounds like the computer is in lock down. My sister has a 99 cavalier and used a cut key to start her car and a couple days later the car would not start. Tried everything then had to get a gm computer to reset the ecu. I have heard about the anti theft systems in GM cars that can cause this as well. Look into it if you cant figure anything out. There might be a code to input into the radio to take it off as well.

My kodak digital camera wont stay on!

Your problem could be the result of corrosion on the battery terminals inside the camera. Remove the batteries and clean the battery contacts inside the camera with a soft cloth (a heavy buildup on the contacts may require cleaning with a fine wire brush, steel wool, or sandpaper). Remove any residue that the cleaning leaves in the camera, clean both ends of each battery, and then reinstall the batteries. This clears most power-on problems, but if yours persists, check the Kodak troubleshooting guide at:

Curved blue lines on screen.

You have a completely different problem. The screen voltage for the blue picture tube is slightly too high on your set. This will put fine lines in the background of the picture, called retrace lines. This is very common and easy to correct. Remove the front speaker cover and the access panel behind it. Look inside and you will see a black box with six controls, each control having a little white glue on it. This is the Focus/Screen block. Three controls are labeled Focus and three are labeled Screen. The screen control in the center is for green but I am not sure if the screen control on the left or right is for blue for your model. With the TV on, set it to VIDEO 1 but do not connect anything to the VIDEO 1 jacks. This will produce a pure dark picture, showing any faint lines in the background. Choose one of the screen controls and increase (turn clockwise) it slightly. If the blue lines do not get brighter it means you are turning the red screen control, so put it back where it was and choose the other screen control. When you find the blue screen control, decrease (turn counter-clockwise) it until just when the blue lines are gone. If you want you can check that the red and green screen controls are set to just below the point where their faint lines are visible. When done, replace the panels and your picture will be back to perfect.

Tiny blue dots and ablue cloud at the bottom

There is a possibility that the symptoms that you described is covered under an additional warranty, even if your set has been out of warranty for years. Sony has a site that describes this repair at no cost to the consumer: If this is not covered, then, the blue light panel is going out and that means it needs a light engine. Good Luck
