Question about Lowrance LMS-332C GPS Receiver

3 Answers

LMS 332c Power cycles on own

Had problem intermittently end of last year, now can't connect power without unit powering self on and rapidly cycling through brightness levels. I saw in another site for 337c's that the owner contacted Lowrance and had unit repaired. Lowrance reportedly said not to expose unit to high temps. Ok then how about some cooling fins? Or a warning somwhere in the front of the 200page manual?!? Trying to call Lowrance now and getting busy signal at 10AM Central time. Not exactly happy right now. Considering self repair since out of warranty antway.

I've repaird this by installing a secondary powerswitch and disconnecting the power switch on the keypad. It's an involved repair but it can be done.

This is a definite malfunction in the keypad and it will need to be replaced/repaired. If you can't get a hold of Lowrance support by phone, try emailing them at http://www.lowrance.com/en/Support/Product-Support/Contact/.

The repair charges for an LMS-332 out of warranty right now is like $199.95...so you might want to look into just putting that money into a new upgraded model like the HDS-5.

Self fix won't work. Display heads are sealed with nitrogen from factory to prevent moisture from developing in unit. Local electronics firms may open it up and fix it BUT they cannot re-seal with nitrogen.

Before going that route - stick with trying to get a Lowrance factory repair - if they are still supporting that unit. My LCX -15MT died and they no longer supported it. Took it to local marine electronics tech shop and they couldn't fix it even after opening it up. I would have been OK and let it run until it died without "nitrogen" if they could have fixed it - but no luck.

Hello
I don't know whether you have made a factory reset to this device or not. If not, set it first and see whether it helps you. To make it factory settings:
[1] Press 'MENU""MENU" (down arrow to system setup) "ENT" (down arrow to RESET options/ ENT
[2] The unit asks if you want to reset all the options. Press [<---] to YES and then ENT. All options are reset, and the unit reverts back to map page at 4000 miles zoom range. Any recorded sonar logs of GPS data will be unchanged. OK.

I have a lcx 110 lowrance graph that wont power up at all. i replaced all the wiring to the unit and tested the plug at the unit all of that is good i also cleaned the connections still nothing. any ideas?


I have found several units that have the same problem. All turned out to be a defective keypad. And almost all are specifically the power button. Not something Lowrance will repair. I've been purchasing some of these units for parts. If you still have it I might be interested. jadamec@yahoo.com

Our unit will not power up


Hi urcvrdha,

You have an elaborate unit! I like these. Your problem sounds more electrical than software related. Try taking all power off the unit for about 30 minutes, then powering up again. Of course, check your fuses. If you get the unit back up to the main menu, and things are not working properly, go to the various "reset" options in your manual for that mode of operation.

If it does not succeed in getting power, I recommend contacting your local Marine/Lorrance dealer for service.

If you don't have your manual handy, download one here:

I hope this adds a little information to your problem search. Thanks.

Regards, Bill

Units flashes when turned on --won't stop

Here's my LMS 332c circuit board. I'm showing where the power source is on the lower right, and where I believe the first two ribbon cables that lead to the power switch on the front panel (upper left). Can anyone tell me how to disable the internal power switch and where? I want to install external switch and bypass the internal. I can solder and not afraid to try since this unit is out of warranty and is not functional as is with powering on/off and screen flashing randomly. Thanks!

Hi,when i switch on my lms-332c the map does not come up on the screen.If I remove and replace the map card it works perfectly. Can I fix this? regards nigel


I am guessing that the card you are using is a NAVIONICS chart? There have been some Lowrance units that were made around the same time that have had problems recognizing a Navionics chart right from power up.

Make sure the LMS-332 has the latest firmware version which can be downloaded from http://www.lowrance.com/en/Products/Marine/Full-Size-SonarGPS-Chartplotter-Combos/LMS-332C/Downloads/LMS-332C-Software-Update/

If the update doesn't help, this is going to be a compatibility problem with the LMS-332 and that particular card. You will need to replace the card or upgrade to a newer unit...but probably can just get used to removing and replacing the card when you turn the unit on.

The LGC-2000 is bad would be the most likely cause, but if this started right after you changed the cables, Try connecting the NMEA 2000 network to a different power source than the main power. If you still have the original cables, and you didn't have the problem before, try using those again to make sure there isn't anything wrong with any of the new cables.

But most likely, the LGC-2000 is toast and you will want to contact Lowrance support to see about getting it repaired/replaced.
