Ok guys I have a sony stereo that the output transistors blew out in. The unit used to just stay in protection mode but now doesn't work at all and last time I plugged it in the relays just clicked rapidly and I believe a transistor got smoked. Now I am not really good with electronic trouble shooting so this is kind of a learning experience in hope of getting it back working also. I know it is more cost efficient to just buy a new one but like I said its a learning experience.
I found some heat spots on the board where it looks like a transistor burned and another piece I dont know what it is. The resistors look fine and so do the capacitors. I plan on removing most of the parts from the board and testing each one to see what I can find thats burned out. What are the chances of me fixing this stereo?
Also it has 3 chips on it, do these normally fry. I dont think they could be replaced very easily.
Here are some pics.. I marked the burned spots and what is that piece I put in the red box?
