Top 20 Lowrance Lcx 28c Hd 7" Gps Fish Finder Combo With 200 Khz Tm Transducer Questions & Answers

From your crank battery...

Same thing happened to my older model. Going to research it today. Mine was on a hot day and Matt have over heated. After recharging the battery it no longer comes on at all. Let me know what you find out if anything

I install these and other Lowrance systems. For me there is no specific amount of tourque, it's primarily your best judgment. You want the bolt tight enough so that the transducer doesn't pivot while on plane but if it were to collide with something it would pivot up out of the way.

The manual is here... http://www.lowrance.com/en-US/Products/Fishfinder-Chartplotter/LCX-28C-HD.aspx and you can contact Support here... http://www.lowrance.com/en-US/Contact-Us/

the unit will pick up anything in the water. Btw, I’m available to help over the phone in case u need at https://www.6ya.com/expert/sean_54c3a3dc48a7773c

Make sure it is completely powering down and you are not just dimming the brightness.
Are you powering off by holding down the power button until shutdown, or are you choosing power off from the popup menu and pressing ENT. Go with pressing ENT on the power off option. If you are completly powering it down for sure, there is probably a malfunction and you'll need to get it taken care of.

Unplug the power cable, and then plug it back in...does the HDS-7 turn on by itself now? If yes, there is a probably short in the keypad, likely due to water intrusion. You'll need to contact Lowrance support at 800-324-1356 or you can email them by going to http://www.lowrance.com/en/Support/Product-Support/Contact/ to get it taken care of.
Give them your serial number and name and address and phone number in the email to hopefully speed up the process.

You need to purchase a EP 60 fuel flow meter. Once you have it installed in your boat, you need to monitor it. You set it up under NMEA DEVICES on your setup menu,

Does the image come back by itself if you slow down or stop and wait? If not, make sure you are not leaving the coverage area of the chart you are set to. In the LCX-20, that Navionics chart is split up into several sections, if you have one section selected and are on the border and then leave that area, the map usually goes all white depending on your zoom level. If you are on a border like that you will have to learn to quickly switch the charts from the MAP DATA menu.

If the map does catch up when you slow or stop, and just can't redraw fast enough...

Make sure the LCX-20 has the latest updates which can be downloaded from http://www.lowrance.com/en/Downloads/Product-Software-Updates/
These updates often add additional Navionics support.

Most likely though, this is just going to be the way it is with that particular map and the LCX-20. If you zoom out it will be much much better. So if updating doesn't help, zoom out. Experiment to see how close you can be zoomed in while running above 20mph. If you can get a good zoom level to where the map can keep up and you can still see the information you need then you should be good to go. If not, use the LakeMaster card or go get a different mapping option...or upgrade your display unit.

I had the same problem with my handheld Lowrance Hunt C. After installing the card and locking it in place, I had to slide the card "out" toward the locking mechanism. It barely moves, but worked after that. Whenever I load the card, I now slide it out or wiggle it and it works every time.

"GPS Module Not Responding" is the display units way of telling you there is basically no GPS module connected. You didn't say which unit you have, so I am assuming this is something like an LMS-520? The GPS module is the LGC-3000? If this is the module you have, make sure that you have powered the NMEA 2000 network. The display unit's power cable has a set of red, black, and sheild wires that need to be hooked up to a 12VDC power source. There is a power diagram somewhere in the manual that should show this.

Make sure that you have the NMEA 2000 network connected properly. If it is a newer version, it should just be a single 15ft cable that has two female ends, the module plugs into one end, and the other end plugs into the back of the display. If it came with some T connecters and 120Ohm Terminator caps, then make sure you have that hooked up correctly. There should be a diagram in the manual for that as well but you just connect the two T's together like TT, put the 120Ohm terminators at each end, and run the extensions to the display and GPS module.

There is a decent troubleshootin guide for checking to make sure power is getting to the module at http://primus.lowrance.com/support/resultDisplay.do?gotoLink=92&docType=1000&contextId=426%3A92.273%2C600.639%2C92.113&clusterName=ClusterPublic&lang=english&docset=%2FDocuments%2FTroubleShooting%2FNew+Utility&contentId=42296cce-4f9b-40c8-9dcf-33d5df754009&responseId=135ccbe2cfd4f608%3A1fe88d%3A1225c5cc17c%3A-bac&groupId=4&answerGroup=1&score=986&page=http%3A%2F%2Fprimus.lowrance.com%2Ficr%2FTroubleShooting%2FNew+Utility%2FNU_GPS_ModNR.htm&result=0&excerpt=Module+Not+Responding+The+GPS+module+not+responding+(early+GPS+products+may+also+indicate+coupler+not+responding)+indicates+that+the+unit+and+module+are+no+longer+communicating.&question=gps+module+not+responding&resultType=5000#Goto92

If this doesn't tell you anything, most likely the GPS module is bad.

I too have lowrance unit which is the reverse. it is powering up by itself as opposed to not powering up,despite checking fuses/lines which are ok. If you are lucky enough to be under warranty, take it back. If unlucky, you too, like me have paid big bux for something that has perhaps lasted only a few years and should last a lot more, given what you perhaps paid for it.
Technical expert advise is that initially the unit will power up by itself but now has progressed to not powering up.You may have a problem with the keypad failing. the bubble type press pad. The wiring shorts and the unit jumps voltage across the keyboard which "tricks" the unit into thinking that you have pressed the power key. After a period of time the unit problem will just progress to not powering up at all. basically the unit has ulitmately failed with time. Short of perhaps definitely stating the unit hasnt been hit or dropped, i suggest if you are in Oz, contact lowrance service in Sydney who are happy to help. they have a possible solution whereby you send in the unit, and they check it.
Generally if not deemed repairable they will replace it with a new similar unit. the only catch is you are up for X (few hundred dollars). this might seem a bitter pill, but you are only charged about a third or half of what a new replacement unit would cost. they give you an updated current model similar to what you have. Im prepared to take that option as it is a cheaper alternative to starting again and paying top dollar. Ive never experienced a power up/down and short of yelling at my son thinking he was playing with the unit, i will have to eat pie and realise with these sort of temperamental gadgets they can fail in the un normal way. Hope it helps. Kahuna 430

Question edited for clarity. Make sure you got the correct transducer Your model comes in single frequency and dual frequency. Make sure the connection on the back of the unit is good and you have no corroded or missing pins. Make sure the software is up to date.

Not available online and one article says updates come from Lowrance. https://www.google.com/search?q=Lowrance+LMF-400+digital+gauge+software https://www.google.com/search?q=LMF400_Low_upd_v150.luf ..

It is a known issue with that unit. https://www.google.com/search?q=Lowrance+HDS8+fishfinder+comes+on+and+then+shuts+off ..

Question edited for clarity. The first thing to check is the fuse to the unit. The could be a fuse block for accessories on the boat, or it could be an inline fuse to the unit itself or both. The pull all the plugs from the rear of the unit and check for corrosion. Spray with WD40 and replace the plugs carefully and tighten the fixing screws evenly. If that doesn't fix it, it may be the transducer, but you should still get a picture for chartplotting. There is no way to check them for correct operation, but try this https://sportfishingbuddy.com/how-to-tell-if-transducer-is-bad/ so if all that fails, you will need to return it for repair. There are some troubleshooting ideas here. This easy fix is on the Lowrance site *Screen goes dark?: If your display turns on, shows the blue Lowrance screen, and then goes completely dark, most likely you have accidently shut your backlight off while powering off your unit. To resolve this problem, once the unit is powered on and the screen is dark, simply press the "Power" button a few times until the screen brightens back up. Do not hold the "Power" button down, just quickly press and release the button. To prevent this from happening again, when powering off your display, simply press the "Power" button one time and then select "Power Off." This will save all settings and features and safely shut down your display. https://www.lowrance.com/help-and-support/?guideTitle=Display-Problems&guideId=003-043 https://www.google.com/search?q=lowrance+HDS+12+repair ..

The model Elite 5x from Lowrance is a bit out dated, I currently have one on my boat, That model would require GPS signal to be able to read MPH unfortunately it does not. Not sure if they made a GPS puck for that model. That wire lead set can and probably is being used on a few different models that support that function. Hope that helps.. BTW I have had mine since 2013 and still works great. There is a GPS speedometer available through LOWE boats with 4 INCH bezel. I am a LOWE boat dealer, General Manager at Beacon Marine in Junction City KS.

Reset use a soft reboot. Or hard reset make sure you back up all your settings on fish finder with chip or home computer. OK guys so the first thing you wanna do when resetting your unit whether it's soft reset or hard reset we're gonna start with a soft reset which is gonna save any GPS data anything like that so we're gonna head over hold the Power & Page button press the power button we're going to go over and press power button but I'm at the unit but up until you see the warning screen where you have to except the depth on reset Can see we still have our Saved waypoints. OK now I'm gonna show you how to do a hard reset again turn the unit off you should always use the power key never just flip the main power switch to off then press and hold the plus minus key as well as the power key let go of the power key keep holding plus minus until the warning screen comes up in a hard reset your going to delete all data on this year it's gonna be like we just bought it went to the store and bought it and cam home with know data whatsoever no settings nothing OK I warning screen has came up we can let go of her buttons and press except start demo. OK now I'm gonna show you how to do a hard reset again turn the unit off you should always use the power key never just flip the main power so that our unit is off then press and hold the plus & minus key as well as the power key don't let go with the power key holder plus minus until the warning screen comes up and a hard reset is going to delete all data on this year it's gonna be like-you just bought it went to the store and bought it and brought it home no data whatsoever no settings nothing OK or warning screen has came up we can let go over buttons and press except start demo now. OK so now you should not see any saved data so that's how you do a hard reset and a self reset. Load your Data card and shut off the power key. Then turn back on and follow screen steps. This should fix you issues. Walld"

Make sure the transducer is pointing directly down when the boat is in the water. Also, this may help

Contact supplier for support and possibly replacement for a faulty unit.
