F75 acting Funny

#1
I just want to throw this out there to see if anyone has an idea what might be wrong.
I went to the beach the other day with my F75 (original not ltd or se) and all worked perfect. The next day I deceided to clean it because it was covered with sand. I hosed down the coil and shaft about half way up, unscrewed the base of the coil from the shaft and cleaned out the connecting parts, I dried everthing and put it back together. Water never came in contact or even close to the electronics.
I went to do some 4th of July hunting and everything seems to work ok except there seems to be alot of static sound now. I thought maybe it was the new location I was detecting but used it today at a local hunting ground and its still humming and buzzing. I checked the batteries and they are almost new, I did a factory reset and the noise is still there but it occasionally seems to quiet down only for a little while. Any Ideas? There is no coil cover on the detector. I'm thinking I may need a new coil.
Let me know what you guys and gals are thinking any help would be great.

you can try putting it in a hot dry spot...you dont want to get any condensation anywhere....how many coils do you have for it? if you have another, swap them out and it would tell you if its the coil or the control box........these coils are not cheap....im running my 5" coil now as the new 11"dd coil is $189 for a replacement...(ouch)....oh, by the way, first texas does not repair coils....all they do is replace the connector where it screws into the control box........was going to send mine in for repair, my warranty was nulled because i bought it used.....$25 fee just to send it in for admin. purposes.
