Sony STR-DE405 "receiver output transistor check" Questions

...output transistor and the resistors, capacitors. When I opened the receiver, I couldn't discriminate the protection circuit. But I can discriminate the elements such as transistor (BJT/MOSFET), ...

Replace the shorted transistors..... and any bad components in the bias / output section of the amp. That is the most likely the trouble with your receiver although there could be many other problems

...output stage. Noisy transistor? No circuit diagram. I have a Pioneer VSX-D503 surround receiver. It has a scratchy sound coming from the LH speaker only. The problem is in the power stage because it ...

output transistors. Sherwood have used these transistors in their older model receivers. I just replaced those transistors in my Sherwood RX-4105 Receiver, and they work good as well. Before I install

the output channels is probably bad you can check for a short on the output transistors using an ohm meter. Make sure that the receiver is un-pluged. The ouput transistors will be on a large heat sink

...receiver I saying overload and switc power off Disconnect all speakers and see if you get the same error. If you don't , get an ohm meter and start checking the speakers and wires. Anything les ...

...receiver and it goes into protect mode when turned on. Is this something that can be fixed by myself or does it need to go to repair shop. If you have a volt meter you may try and repair it yourself. ...

...receiver. May occur when the output diver transistors of any of the amplifier become shorted. if the output transistor get shorted this will lead to flow of current through the speakers. To prevent ...

RECEIVER IS 5 YEARS OLD.BUT HARDLY USED. Can You help today. Steve The symptom you described can be caused by any number of things. I always start with the output power transistors which are the first

...receiver. May occur when the output diver transistors of any of the amplifier become shorted. if the output transistor get shorted this will lead to flow of current through the speakers. To prevent ...
