Transducer issues - Sonar/depth rarely works anymore

[Juzzbott]

Hello everyone, 

I'm just wondering if anyone has had their transducer suddenly stopped working/very intermittently stop working? I've got a Lowrance Hook Reveal 7TS, with the TripleShot transducer, and the last two times I've taken the boat out, the sonar isn't working, and I have no depth reading, or it's very intermittent in that it will work for 10-20 seconds and then no longer work. My sonar screen looks very similar to the picture I've attached. 

I don't believe it's a placement issue for the transducer on the transom, as it's worked great for nearly two years. 

I've checked the following:

• It's still inline and flat along the bottom of the hull;
• I can get a temperature reading, just no depth or sonar readings
• There doesn't appear to be any obvious signs where it's been hit or damaged
• Unplugging the transducer cable shows that it's disconnected and I lose the temp reading
• The unit is not in "demo" mode or "stopped" mode, and I can still record a sonar log
• It makes no difference if I'm stopped, moving slowly or at speed (I've had it work intermittently at all three)
• Its the same behaviour if I'm in 1m, 5m 20m water etc.
• Factory reset of the unit

I think I've come to the conclusion that the transducer has somehow been damaged and needs replacing, I was just hoping that someone might have something else to try before I shell out for a new transducer?

Cheers, 
Justin

After owning just one Lowrance never again.

Some other threads to look at

This might sound strange but check that the transduce plug is all the way in , as it may look like it is but I had a mate that was having the same trouble.

we found that the plug was a bit dry and wasn`t going all the way in so gave it a spray with some silicon spray.

if you can try another transducer and it still doesn`t work then it is definitely the main unit.

Thanks, I might try with some silicon spray, but it's definitely plugged in as far as it can go, past the two little o-rings for the pressure seal.

To me it sounds like a signal/connection issue, cable could be damaged , pins corroded, all of which will lead to this sort of thing, might be worth getting the floor up to have a look.
