a problem with the output stage of the amplifier and has shut down to prevent further damage. Usually this is caused by defective output transistors. Expect a parts cost in the range of $15-$40. Add in the local labor rate for the total repair bill. Dan more...
Most likely the output transistors are shorted. This causes the output stage to draw too much current and blows the fuses. Expect a parts cost around $20-$40. Add in more...
that a problem was detected in the final output stage. Try removing the speaker connections. If it still behaves the same way, the output transistors are most likely defective and will need to be replaced. The parts cost should be around $15-$25. Add in the local labor rate for more...
and that stage was shut down to prevent further damage to either the amp or the speakers. The typical problem is either the output transistors on one channel or the output amp chip for one of the surround channels. Expect a parts cost of about $25-$40 plus hte local more...
problem was detected in the final stage of the amp section. It could be as simple as a voltage regulator problem or the output transistors have failed. If you can provide the make and model, I should be able to give you the most likely parts. Dan more...
control or switch, working them back and forth could prove that. Other than that, It's likely bad outputs. A unit that old may have transistors for outputs but might be IC's. Transistors can be tested with an ohm meter to see if they're good or not. Also if it more...
