FIx Lowrance x125?

Tucker has a lowrance x125 that will not shut off and beeps and light flashes continously. Problem started after last big heat wave. We keep his boat tarped ,but after reading some reviews online sounds like this unit could not take the heat. Tucker called Lowrance to see what could be done. Customer service said will not do anything including fixing it on Tuck’s dime. Well Tuck’s only 15 and spent most his ching on this boat so getting a new depthfinder seems out. Does anyone know of a place Around Rochester ,MN Tuck could bring unit to to get fixed ? Otherwise Tuck is in the market for a used depthfinder.

Can’t help with the current sonar, but when he finds himself in the market for a used one, try bass boat central.
