If it doesn't show you anything when you turn it on, probably terminal.  It it goes through it's normal display junk and then goes blank it may be the  transducer.  Either case, unless you could find a used transducer cheap, it's not really worth fixing.  There are several better units for less than $200.  Some that actually have some resolution.

Take all the Torx crews from around the outside edge, open it up, unplug and plug all the connectors on the board just to make sure you're not getting a bad connection and look for anything obvious.  If that don't work, s***can it.

ty for reply, i know its outdated, but penny saved, lol.  Now what happens is it turns on, as in push on, beeps, but no LCD, if you put your face right to it, turn head sideways and squint, than can faintly see a screen.  So your suggesting that i take the back off and look for loose connections?  Not at the base where it click in?

Sounds like the problem is inside the sonar, not the base mount.  Sounds like the display drivers are not working.  Maybe all the blue ink leaked out (just kidding).    You've got nothing to loose opening it up and just giving everything a little wiggle, tap, shake, unplug and plug.  

Too bad you didn't post two weeks ago.  I just dumped a number of old units, a good 300TX and a 400TX off my sons boat was among them, they both needed transducers.  Gave several complete, working Lowrance and Eagle units to Salvation Army.

as i wipe the tears from my eyes!!! LOL, well ty once again, thats what I was going to do, was hoping maybe some other ideas. Love this site, dont know if moderators read all posts or not, They should do pike as well. Early to bed, and rise, dont forget to fish like hell and make up lies!  And a quick edit, since hardware store is closed this time of nite,(i need a torx) the light works, lol, maybe its the black ink

LOL

Oh ya, I read 'em.  ;D

[lakeman14]

glad to hear you do.  Any ideas on fish finder? or is it a euchre?

[Bassattackr]

sounds like a faded out screen. Common problem for humminbird fishfinders. In one phrase - SOL. Time to look for a new one. For $299, you can get an excellent unit a Lowrance X125.  Or a X135 for $399.

Lakeman- Pike covered in "other species"

ty, will check for pike there.  Now as for fishfinders, I got a Hummingbird100wide, just the monitor, but thats all, anyone know how old this is, or its capabilities.
