So, I had my PS2 plugged into the front of my Yamaha receiver when lightning hit not too far from my house (I didn't see it coming, honest). Well, a bit of the electricity got through and zapped my receiver. Oddly enough, it works flawlessly except for one thing: All the different inputs are crossed. I can hear the FM, DVD, TV, etc all at once no matter which one I have selected. Is this fixable thing for not too much money, or what?
