Fish TV - moisture behind lens

[Iowabucks]

Hey everyone, i have a Fish TV, 7" model that i have used for 2 years. It has worked good so far, until yesterday i noticed moisture behind the lens. It does look like the lens has threads so i'm hoping it can come off and i can seal it up a little better. I did try to take it off with my hands while i was on the ice and didn't seem like it was going to go. I just don't want to break the lens trying to take it off. My next choice was going to be using some kind of soft jaw pliers to help the lens off, but i'm afraid if it has some kind of glue on the threads that it wont come off without breaking.

Has anyone ever tried to take the lens off, or fix this problem any other way with the Fish TV lens? Any other ideas?

I've never looked at it that closely before. But it appears to be threaded on at the lens cap with a inside silicone seal. Does it have anything in the manual about it or on the web site?

You will need to get that moisture out and well air dried to gain a clear view again, and resealed properly, that is a given.

If it will not come off, I would guess one may be able to drill a very small hole on the lower side to drain the moisture. Then seal the hole with a good silicone and seal all the way around the area where the lens is attached.

That should work but be very careful drilling so you do not cracked the lens.

I would try to unscrew it first as it looks like it should screw off. If not, the other way would be an option.

I put it under a lamp to warm it up and it has went away for now. It may continue to have the problem after using it again, but for now i don't think i am going to take it apart.

I've repaired a couple cams, none were Fish TV, but I'm willing to bet construction is similar.

The cover will screw off. They have a seal on the inside, but they also use a sealant when they attach the cap at the manufacturer. You will need to remove the cover to dry it out, but most likely it isn't the source of your problem. Most likely, it's leaking water in where the wires run in. So when you have it apart, add more sealant around that. That will save you the troubleof having to tear it apart again.

Most likely you hit the lens cap on something solid like a rock on the way down with out even noticing. The bad thing is that you may never be able to see the crack with the naked eye. It is possible that the leak is in the wires, so if you do take the lens cap off do try to seal the cable entrance as well. Im sorry to say but you will most likely have to by a new camea. And we all now that a new unit is almost the same price as a new camera. I now that Cableas has a unit on sale for $99, that is similar if not a little better than the Fish Tv ..sorry I dont have a better answer for you!

I had this exact problem last year and took all response actions that have been noted. The plastic is glued on and cannot be taken off. I drilled a hole in the bottom very close to the threaded area on the lens to ensure it would not be in the way. Lens cleared up nicely after it was dried, however once warm things go from 70 degrees to 32 in the water they condensate. I tried to aclimate it accordingly etc. Final consensus was to call the new FishTV company in crosslake and come to find out, cheap to get it fixed prior to rigging the unit to try to make it work. New camera = 75$ new unit =150. You could call them up to see if they could do anything about it because I would be it is becoming a common problem with the unit.
