My house was recently struck with a lighting surge...I have direct TV satelite..the two Sony SAT HD 300 units were OFF however the surge actually ran through the coaxial line into the Sony units and damaged them..Both were plugged into electrical surge protectors but the surge never triggered the electrical breaker..it ran directly through the coaxial..neither unit after being fried will detect being hooked up to satelite..I have sent both units back to Sony..but I'm looking for suggestions to keep this from ever happening again...Is there a quality protector for the Satelite in line??
