I just resealed 5 windows myself with the help and advice of the good folks on here. Is your water actually leaking inside through the window, or around the edge of the frame. You need at least 2 people to reseal them. There is a trim ring which is the inside frame of your with 20 to 30 screws. This is what holds in the windows. You need about 15 ft of 1inch butyl tape, a torque bit end for your screw driver, a heavy duty putty knife, some rags and mineral spirits.
Just Google TV window reseal, there is a good utube video that shows you the process.
Sometimes, the windows leak at the frame and they need to be reglazed. This is a much more expensive and time consuming process and is best left to vendors that are in the. Business of doing this.
