Lowrance 334c backlighting

[snoozebutton]

I turn it on and the bright light flashes for a second then goes out. The unit is turned on but no lighting so you can just barely see it if it's in direct sunlight. I tried both a soft reset and a hard reset with no luck. I also had a fully charged battery and even switched to a different battery and still nothing. Any idea what's going on with it?

It's probably a gonner.. call the factory. I know someone who went through 3 of these before he got one to work...

It's probably a gonner..

That's not what I wanted to hear but thanks for the response. I'm going to call Monday morning and see if there's anything they can or will do.

Well, good news. Just got off the phone with Lowrance customer service and they're sending out another unit. Should be here for the opener.

Yup and 3 days later my new 334 was delivered.

Not so happy today. First time out with the replacement unit and it did the same thing. Could it be the power source? Like maybe they didn't put a fuse in the line?

[snoozebutton]

I brought it in and had a voltage tester hooked to the front plug and it's 12.78 volts. Is it possible that I had 2 bad units? Doesn't seem likely since as soon as I plug them into the front power source, I get the same results. The original one worked great for 2 seasons until I plugged it in there.

Snooze, I'm sure you've done this but, have you pressed the power button more than once to turn the unit on, to change the lighting setting? off - low - high

Thanks for the suggestion minneman but yeah, I've tried that.

Is that a sonar/gps combo unit? Try disconecting all the cables except the power and see if it works. You may have a bad transducer or gps reciever.
