Should I just buy another one or could it be fixed
Electronics Technician: Electrotech2017, Technician replied 23 days ago
If you have disconnected all speakers from the Sony receiver and the receiver still goes into protect mode, then unfortunately it means that the Amplifier circuit suffered a failure. Sometimes it can happen due to a shorted speaker or speaker wire. But in some cases it fails prematurely on its own. One of the channels has a shortage or high DC offset voltage. The way to check that is at turn on, for the 3-4s it tries to turn on you can measure on the emitter resistors at each channel and check for DC voltage higher then 1-2V. The channel that has the high voltage is the defective Amp. Most likely the output transistors. Average the repair with parts and labor is around $150-160

It is a nice AV receiver. I would definitely recommend to get it fixed. Only HDMI issues are more expensive to fix, since the entire board needs to be replaced. But if you have only an Amp issue, I would get it fixed.
