Hi,

Garmin tech support said it was a problem with new WAAS signals that causes the freeze/black line. Disabling WAAS using menu/system solved it for now. They are working on a software update Real Soon Now.

I read an article in the GoodOldBoat newsletter about the Department of Defense
making changes to the WAAS satellites that have caused problems in Garmin 72
and 76. Garmin's tech support recommended to turn the WAAS function off on
affected units. So I got out my old 162 and turned the WAAS off and it works
fine. To make sure it wasn't a fluke, I turned it off and on several times,
and it always slowed down with WAAS turned on. With it turned off, the
position error or accuracy, increases 1-2ft, not a big deal. I hooked the unit
up on my truck and drove around. Not a problem. Further reading indicates
that other brands of GPS are also having problems with the new WAAS
transmissions.
So if you are having problems with your GPS and it is new enough to have WAAS,
try to turn it off

Thanks for contacting Fixya

My Acer Aspire V5-571 does not load up it shows acer screen when turning on the laptop then loading floating ball comes on screen for a few seconds then black screen ? can any one please help ?


Hi Jim,

this seems like a no boot / no video kind off issue and mostly is coz of corruptions in softwares or drivers, try booting the computer in safe mode. if it does, then take a data backup. i would not recommend experimenting in this issue as it can crash the computer.
hence call 1-877-805-1027 for expert help.

I had the same issue, It actually turned out to be the backlights themselves. An easy way to check this is by shining a bright light on the screen while its on. you should be able to see the picture.

Hello,

the problem is actually a software issue and since resetting does not solve the problem,I think updating the deice should solve the problem. Update is just like reinstall the system software of the unit and it might get things fixed.

To perform update, follow the below procedures;

1. Plug one end of the USB cable into your GPS and the other end into your desktop or laptop computer. The GPS device will load the appropriate driver automatically, and a message on your GPS tells you that it is connected to your computer via USB.

2. Open your Internet browser of choice and type in the following web address: http://www8.garmin.com/support/collection.jsp?product=999-99999-27

3. Download the appropriate version of the software for your computer (Windows or Apple) and Install the WebUpdater by following the wizard (accept defaults).

4. Click "Start," "Programs," "Garmin" and " WebUpdater" to update your firmware and your maps. Periodically check and make sure your software is current.

If the computer does not recognize the Gps, you can try the below procedure;

With the unit OFF, hold your right thumb on the Upper, Left part of the screen and plug the USB plug from your computer into the back of your GPS. The unit should boot up and stop at the screen where it shows a little computer, wire, and little GPS. Your computer should now show the GPS as connected. Only now you can pull your thumb from the screen.

Then use Webupdater to upload 4.40 to your GPS.

Hopefully, the above should be helpful

Good luck.

My monitor goes blank after a few seconds of turning my computer on. I turn off the monitor & turn it back on again and it only stays on for a few seconds thanks


It basically goes to Power Save Mode. Check for the same error in System Setup screen, if the Monitor goes off in System Setup then you better need a replacement. Else you would need to reseat the Video Card(If any) and the Memory Modules. Please keep posting for any further issues / improvements.
