Hey there! Welcome to the Forums @pmh62! 
When you're working out it is normal to sweat and obviously your body gets warmer, but even though your Surge shouldn't be having hardware issues; since it is not normal to have fog in your screen and if the backlight is not working either, it's best to contact Customer Support, so they can give you the next step for this situation.
In case that you have any questions about it let me know, I'll around!
