I had a rather high end receiver given to me. It stopped working and the repair shop just opened it, verified the fuses were good, and told him to buy a new one...
It will turn on, then shut right back down with a blinking light. After some fishing, I did find what "might" be a concern. Testing + to - on all the speaker outputs, I found that the center channel is a dead short. One might immediately assume the transistor is toast but they are all testing fine. I am thinking the issue might be right near the output for the center ch. There are a few ceramic caps and a few power resistors and a relay that I am not quite sure about yet. I have never seen a ceramic cap fail but I guess it is possible.
I do have the manuals for the unit but not real sure what to think of this low resistance on the speaker output just yet.
