    Lowrance LCX Repairs.... No bashing Lowrance on this thread

    Hey ya'll, I'm looking for some insight from anyone who has ever tried to repair an LCX unit by themselves. I know lowrance doesn't help and I'm not looking to start another argument about their customer service as that has already been done enough in other threads. My LCX 111c hd has had a problem with about 2in of the screen flickering about 80% of the time, some days it works perfectly though. Also, there is a problem with the sonar. You can actually hear it in the transducer (which is new). The pinging is very erradic and inconsistent (causing poor readings). Just wanted to know if anyone has ever had these problems/ tried to fix their own units with success.

    The ping noise sound right. it clicks real fast few times, then it slows down for sec or too. As for your screen flickering are you getting enough volts to your unit when this happens?? Next time it does this take a snap shot on your phone and let us see what you are seeing and talking about.

    Depends on how much you use your unit, but alot of the time when the screen starts flashing like that it means the pixels are starting to die. Unfortunately the only way to get that fixed is if you get another LCX-111 and get the screens replaced since Lowrance doesn't work on the old units anymore. As for the transducer, is it just a normal transom mount, or a shoot thru the hull?

    As for the screen, its definately not a power issue, its something internal. I havent taken it apart yet to see if anything is out of place b/c I dont know exactly how those screens work.
    The transducer is a trolling motor mounted puck. I wasn't having problems with it until recently and here is the crazy story why. Everything was working fine, then I bought a refurbished hds8. The sonar wouldnt work at the console so I took the hds and plugged it in to the front (where I have the LCX). The sonar wasnt working on the hds there either, so I sent it back got a new one. Now when I plugged the LCX back in it wont read sonar. I took someone elses unit and plugged it in and it worked fine, so all my transducers are ok. Something happenned to the LCX when I plugged it in after the faulty HDS and screwed it up. No one has ever heard of this happenning and lowrance was baffled. I think it may have fried the transmitter inside the LCX somehow. I'm reading temperature fine so its getting power, and occasionally i will get a depth number, but no bottom reading (extremely faint reading if anything). So thats where I stand on that situation.

    Your only hope is to find another unit with a different problem and use the parts to make one good one. Parts availability is the reason nobody works on them. All custom parts and most are obselete technology.
    Stay strong Lea!

    May have found the problem for the sonar. Took the unit apart today and noticed a severed terminal to what i believe is the transmitter for the transducer. Little bit of solder and i think it'll be right again. didn't notice anything wrong with the screen connnections so still stuck there. hopefully i get a chance to test in the next couple of days.

    I had an Eagle 480 on my small lake boat and it had a problem with the backlight coming on and off at random. Since it was way out of warranty, I opened the case and found the keypad ribbon cable was barely seated in the socket. Pulled it and firmly reseated the cable (did the same for the other ribbon cables too). Been working fine for years ever since.

    Since it's not like Lowrance is working on them, what do you have to loose by cracking open the case if you are even a little tech savy?

    I know some of the items are proprietary, but I'm surprised no one is working them on the secondary market (other than the guy in China on Ebay). Seems there would be a demand and there must be plenty of parts donors and dead units to be had for cheap.

    My thoughts exactly. The only problem is finding people that arae getting rid of bad units.

    I agree! I've been able to fix a few small issues over the past years by cracking open my units and making sure a connection hadn't come loose.

    Some units had moisture intrusion issues which obviously cause a lot of different symptoms. If you have the case open...(don't laugh at this point :)), if you have access to a dehydrator like you make jerky in...put the unit in the dehydrator for a day. It will allow any hidden moisture to evaporate...if it already has problems it sure can't hurt.
    Electrical contacts and corrosion are the favorite culprits....while apart, spray those with Caig Deoxit electronic cleaner. It is a professional product; carefully apply to only the electrical conductors and will it chemically clean electrical contacts. I have found it on line and sometimes at Radio Shack but they are pricey. Do not use WD40! Just a couple ideas....GL
