Measure DC to ground on the output transistors to check for any offset. The protect circuit is the least likely to be the problem. Post the readings here and I'll guide you from there.

SOURCE: No sound at all. Power is on and all lights light

I do not have experience with this particular amp. Generic trouble shooting follows:

Might it be that you have headphones plugged in? (Unplug them, they turn off the speaker output) You are absolutely certain of the settings on your amp? (check them again) Are you certain you have an input? (AM, FM, CD, AUX, other) (Make sure the input is turned ON and the source is properly selected.

Is the output protected by a fuse or fuses? (look on the back panel for fuses or fuse holder)

Everything that is suppose to be plugged in IS plugged in ... all cables are intact? Did you check them for contunity? You can check contunity with a flashlight battery, the light of a flashlight and a paper clip.

Speaker selection switches are pressed as appropriate. Speakers are connected to the appropriate outputs and they are ON. Speakers are of proper rating - and resistance? 4 ohm - 8 ohm - 16 ohm??? Any controls on the speaker are set at a neutral setting?

I'm sorry your device is not functioning as you think it should. These things are designed to work and generally, they are pretty good at it. Sometimes, they just break (stop functioning) It may be that you will have to take it back from where you got it for repair or adjustment. But I am hoping you have the headphones plugged in.

Marantz SR19/U1B 5.1 AV Surround Receiver Unit powers on but will not play audio out of any of the speaker channels. Buttons respond. No further testing could be done with my knowledge.


The receiver could have gone into protect mode as a result of incorrect speaker connection in which case there should be some indication on the front panel.. Check all speaker connections as even a short between wire strands can shut down the receiver output. You may have to open up the receiver to check for open fuses in the output.

No sound from TV


check the fuse output line in the speaker! or maybe you are in protect mode! checkout the speaker, maybe you have defective speaker, thats why your unit in protect mode, thats why no sounds coming out!

Harman Kardon AVR 7500 Does not power up and can't find fuses!!!


Honestly, if you are talking about the speaker protection relay, the relay and associated circuits rarely go bad but instead respond to problems elsewhere in the amp. Anything from defective speakers, bad spkr. wiring to output transistors will cause this protection relay to not energize thus protecting the output stages and speakers.

My amp has a protection light on need to know how to fix. When I pull the fuses out the power comes in but when I put the fuse back in the protection light comes back on


From the description your audio output transistors or ic's have a short causing a load problem activating the protection circuit. Turn volume right down, power off, remove speaker wires from the back, power on! if protection kicks on it is the audio outputs in the receiver, if not! check speaker wires for shorts, hook back one at a time until defective wire or speaker is located. The audio outputs will need to be addressed by a technician since there is complexity involved.

My Sony STR-DG510 has quit outputting to my speakers (via stranded speaker wire). I suspect a blown fuse but no fuse is visible on the back panel. What's the secret to replacing the fuse? Thanks!


Sony strdg510 does not have fuses on the output, it uses an output relay. If you do not hear the second click about 6 sec. after powering it on, there is a problem in the output circuit. If you do hear that click, check that the speakers are on and tape 2 / tape monitor is off and that the speakers and wiring are good.

No sound out of left speaker


did the left channel work when u switched speakers, if so then the left speaker or wiring is a fault.if not then the output circuits on the amp are blown or the fuse is blown some amps have internal fuses in the output to protect the output transistors. unplug the power cord and take the cover off, look to see if u can find any fuses and check these for continuity u can hold these up to the light and u should see a fine filiment in one piece and not broken. these fuses sometimes blow just from age and use at high volume like a regular light bulb.If the fuse is blown replace with the same value else the output transistors will need to be replaced most likley along with the drivers.

All lights operate on front panel but no output to the speakers


Hello, your unit is in "protect" mode. The protection circuit is activated to protect your speakers from a shorted output IC or output transistors. If there wasn't a protection circuit then the shorted output would send it's operating voltage straight to your speakers and the speakers would literally fry.

Lost speaker output at rear of unit


Check the continuity of your speaker cables either by using them on another system or with a test meter. Could be that the cables got damaged in the move.

No output from outputs to speakers.


Usually the outputs are not fused, but you can go thur speaker white noise test and see if that works first. If it does, then outputs are probably fine, IF not then the output transistors are most likely bad. Let me know and we can try some other things thur live chat if you would like. Good luck Guru Jay
