Question about Sony STR-DA90ESG
I'm trying to repair the same model receiver. it shorted out during a storm and no surge protector was used. while i am not experienced as the rest of you, i would like to determine the cause of the problem. i took the top off and there are three circuit boards relating to power; the first has 3 fuses, the 2nd two fuses and the 3rd i believe 2. All of the fuses are fine. what else could have shorted out -- the output transistors? i don't know what they look like or how to test them. what should i look for?
