You are probably right, the circut board is fried. I have had to send in numerous collars due to water damage.
Call Gramin, they will give you a confirmation order, & address to send in the collars. Turnaround is usually about 2 weeks.
Anytime you take a collar apart to either reset it or change the battery, make sure you use silicone or some other rubber gasket material. Other wise that collar will leak for sure. If you hunt a lot around water like I do, it is a real problem.
how much is it do you know
