LMS 337c DF. The LCD backlight seems to jump from bright to off and back continually after the unit has been on for 10-15 mins. holding finger on the power/light button stabilizes the problem until the unit swiches off.

The lcd is going out and will cost more to fix it then the cost of the gps....my advice is to get a new one from bestbuy and get the 4 yr performance service replacement plan so next time you have a problem like this they will replace it for free.

How do I fix the backlight of my garmin 3205


The LCD display contains both the display and backlight. They are integrated as one piece. Therefore the entire display needs to be replaced. The backlight connections are soldered to the LCD connections. Replace the entire display.

The display is dim and hard to see.


First, make sure that your brightness is turned up. You can access this from the menu by selecting "Display" then adjusting the display between 50% & 100%.

If the brightness is at 100% and the display is still dim, this is an indication that there is a problem with the backlight that lights up the LCD display from behind.

The backlight is integrated into the LCD display, so the entire display needs to be replaced. Was the unit dropped? If so, perhaps the LCD flex cable pulled out of the connector, slightly from one side, disconnecting the backlight. We strongly suggest that you don't try to repair the unit yourself. Additional damage can occur.

Is there an external antennae for the lms 527 combo available


  • No it does not. Lawrance often makes either external or internal GPS units. This is an internal antenna unit only model. Hope this helps.

My Lowrance LMS-337c df keeps going crazy.


Normal 0 false false false MicrosoftInternetExplorer4 st1:*{behavior:url(#ieooui) } /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin:0in; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:10.0pt; font-family:"Times New Roman"; mso-ansi-language:#0400; mso-fareast-language:#0400; mso-bidi-language:#0400;}This could be caused by glitch in the operating systemsoftware or by low voltage due to a short in the unit or somewhere in the boatswiring. To troubleshoot the problem Iwould recommend the following steps.

  1. Try a soft reset
  2. If the problem resurfaces, try a hard reset
  3. Update the the operating system software

Soft Reset (Does not delete GPSData)
1. Turn unit OFF 2. Press and holdthe PAGES key
3. Press and hold the PWR key
4. Release both buttons when the USA map
Appears

Hard Reset (Deletes stored GPS Data
such as Waypoints and trails)
1. Back up any waypoints, routes,and trails that you want to save on a blank MMC card
2. Turn unit OFF
3. Press and hold the ZIN&ZOUTKeys at
the same time
4. Pressand hold the PWR key
5. Release both buttons when the USAmap
appears

Gps


I have a manual for this unit but i'm still using mine so not willing to sell it to you. I'm in Melbourne and you're welcome to borrow it for a week or so or i could probably photocopy/scan certain sections for you and email them if it helps. Let me know if you still need it by emailing me at joshklat@hotmail.com

Cheers,
Josh
