Russound 6.6 Lightning storm blown unit?

577 Views 2 Replies 3 Participants Last post by  rekbones
Had a lightning storm a few months ago, and ever since unit has not worked. Recently took cover off and noticed 1 of the 2 fuses had blown. Changed both out for new ones. went to turn on, this fuse blew and sparked. It's labeled in the D row. House was under surge protector and wondering what could be the cause of this.

That isn't a fuse. That looks like output transistor module. Time to get a new amp or find a rare bird that still knows how to diagnose / solder.
Surge protection has very little protection against lightning damage. Only if lightning strikes the the power lines will it help and this very rare. 90% of damage to electronics during lightning storms is caused by ESD (electrostatic discharge) and effects the low voltage drivers where an external wire is connected, the longer the wire the more like an antenna to the pulse. The fuse blows because you have a shorted component and the above looks like a driver IC.
