My sonar is only reading the surface and nothing else. I hit a wave and it worked properly for a couple of minutes then went back. The connections seem fine and the transducer is in the proper position. Could this be an internal problem or do I need to replace the wirrinig or transducer? Thanks, Ken
First, ensure that the transducer face is pointing down when the boat is level in flat water. You may want to do this step like a tv antenna, adjusting the angle of the transducer while watching the screen.
If that doesn't work, then try moving the transducer further into the water and repeat step one.
Sonar systems are (largely) directional, and will work best when parallel with the seabed (or lake bed etc)

Had the same issue with another brand. Turned out the transducer cable was picking up noise from other cables (power, trolling mtr. etc). Try moving the transducer cable away from any other cables. I put the cable in a 1/4 " plastic housing up to the point where it was above deck and it stopped all the strange stuff. Not sure about the temp issue??

MY XD510c works fine then flashes 2.5 and fills the screen with black red blue white vertical lines...then after an amount of variable amount of time goes back to working for awhile
SOURCE: LCX-25C seems to be cycling on & off when in the sonar mode.
I have a lcx-25 from year 2007 with same kind of problem. Service found o lot of condensed water inside. These devices are not water or gas proof. There was oxidized connectors etc. Maybe local electronic mechanic could help you.
