I've had a M260 feeding my Navnets since 2006 - never an issue except for topping off the non-tox a couple of times. This year it sprung a leak and since it was almost impossible to reach I had the Marina reseat the box. They did what seemed like a nice clean job with 5200. It no longer leaks.
But - I got on the boat last week once it was "done", and I get no depth. Figure they just did not top it off, so I made sure it was filled. Still nothing. I go fishing Thursday, no depth reading, but I fiddle around in 80' or so and in manual (I almost always use Auto/Fishing) I can get bottom if I crank the gain up to 80+. Well, I can see a decent bottom picture, but no depth number displayed on the screen dedicated to FF, and no depth on the data field on my other screen. "Auto" returns absolutely nothing.
Fiddled all day today - I tried switching to LF, and that works. Whoopie. Works fine in auto mode, depth displayed on both screens. But HF is still fubar. If I display as two frequencies, LF is fine, HF is dead.
Any thoughts on where to poke next?
Thanks.
